do we get fatter with age yes between 20

0:03

and 50 years old the average person will

0:07

gain about 15 kilos in weight I don't

0:09

want to be that guy what can I do okay

0:12

so Dr Giles yo he's the world leading

0:15

expert on fat and how to burn it his

0:16

book is called why calories don't count

0:19

what you eat does matter let's talk

0:21

about how we fix the Obesity how we burn

0:24

fat how we all get into a healthy weight

0:27

everyone's brain hates it when they lose

0:30

weight we're talking even a few pounds

0:31

it goes this is reducing my chance of

0:34

survival the moment you stop the diet

0:35

the weight will come back on calories

0:37

are not accurate what's the truth the

0:40

calorie tells you absolutely nothing

0:42

zero so if you actually look at a stick

0:45

of celery Raw it's got only six calories

0:47

if you cook the celery that's six

0:50

calories becomes 31. understand the

0:53

limitations and caveats of calories

0:56

veganism what are the general

0:58

stereotypes that need addressing

1:00

veganism plant-based in particular is a

1:02

diet for the privileged people who can

1:04

choose to do so we do not need everyone

1:07

to be vegan sustainable weight loss what

1:10

is the way that you would suggest to do

1:12

that the simple way hey it is the set of

1:15

numbers that you can apply to whatever

1:16

diet you like so the first is

1:20

let's talk about something else which I

1:21

feel like I was lied to about oh God

1:23

which is juice oh yes

1:28

I just want to start this episode with a

1:30

message of thanks a thank you to

1:32

everybody that Tunes in to listen to

1:34

this podcast by doing so you've enabled

1:36

me to live out my dream but also for

1:38

many members of our team to live out

1:40

their dreams too it's one of the

1:42

greatest privileges I could never have

1:43

dreamed of or imagined in my life to get

1:45

to do this to get to learn from these

1:46

people to get to have these

1:48

conversations to get to interrogate them

1:49

from a very selfish perspective trying

1:51

to solve problems I have in my life so I

1:53

feel like I owe you a huge thank you for

1:55

being here and for listening to these

1:57

episodes and for making this platform

1:58

what it is can I ask you a favor I can't

2:01

tell you how much you can change the

2:03

course of this podcast the the course of

2:05

the guests were able to invite to the

2:07

show and to the course of everything

2:08

that we do here just by doing one simple

2:10

thing and that simple thing is hitting

2:12

that subscribe button helps this channel

2:14

more than I could ever explain the

2:15

guests on this platform are incredible

2:18

because so many of you have hit that

2:19

button and I know when we think about

2:21

what we want to do together over the

2:23

next year on this show a lot of it is

2:25

going to be fueled by the amount of you

2:27

that are subscribed in that tune in this

2:28

show every week so thank you let's keep

2:31

doing this and I can't wait to see what

2:32

this year brings for this show for us as

2:34

a community and for this platform

2:36

[Music]

2:43

Giles hello a pleasure to sit with you

2:46

I've been a big fan of your work for a

2:48

very long time and I've consumed many of

2:50

your YouTube videos conversations you've

2:52

had interviews and these fantastic books

2:55

you've written but I want to I want to

2:57

start by asking you to give me a bit of

2:58

an overview of your academic Journey as

3:03

a as a researcher

3:06

um as a graduate of Cambridge and an

3:09

overall flavor of the work you do the

3:10

experience you have and the expertise

3:11

you have

3:13

so so I am uh I'm from San Francisco

3:16

um that's where I did my high school I

3:18

did my undergraduate where I studied

3:20

um genetics that's what that's why I

3:22

studied as an as an undergrad then I

3:24

came to Cambridge to do my PhD

3:27

um and I worked on the genetics of the

3:30

Japanese puffer fish Fugu Rupert Peas I

3:33

I know I know so there's a long reason

3:35

why I did that but I was looking at

3:37

molecular evolution

3:39

um so and I was well trained as a

3:41

geneticist but then I realized that

3:42

genetics of pufferfish was not going to

3:45

pay my mortgage and was at this point I

3:47

needed a job so I finished my PhD I went

3:49

knocking on doors actually I didn't look

3:51

at any adverts or anything I just went

3:52

the department I said you know what I'm

3:53

just going to see if anyone has a job

3:54

and the second door I knocked on was a

3:57

guy named Steve O ratley and he had just

4:00

identified the very first obesity gene

4:03

in humans when mutated cause really

4:05

severe obesity This was 1998.

4:09

um and I joined this lab I was I was

4:11

from a famous lab I was a geneticist he

4:14

needed

4:15

um he had just found the first obesity

4:17

genetics genes he needed a geneticist

4:19

that's how I got into genetics of

4:22

obesity so that's how I started and then

4:24

I started with the genetics of severe

4:27

childhood obesity so

4:29

um kids who are three years old but 100

4:33

pounds so so this is not we're not

4:35

talking just a little bit chubby just

4:38

just drink too much uh Coca-Cola type

4:40

type of things I mean these are

4:41

mutations which cause really really

4:43

severe obesity that's what that's where

4:44

I started my career where they can't

4:46

stop eating they can't stop eating

4:49

because in particular

4:51

so because they lack the signal between

4:55

fat and the Brain there is a signal it's

4:58

a hormone which lets your brain know how

5:00

much fat you're carrying that's

5:02

important because how much fat you're

5:05

carrying is how long you would last in

5:07

the wild if there was no food so if your

5:09

food sources stopped today so it's an

5:10

important piece of information

5:12

but if you lack that signal like some of

5:15

these children do this is one of the 100

5:17

pound kids I was telling you about then

5:19

what they have is a brain that thinks

5:21

that they're starving because now

5:22

there's no signal so the brain thinks

5:24

they have no fat when don't you have any

5:26

fat when you're starving and so these

5:28

poor kids who we think and we judge look

5:31

at that fat kid what's that look that

5:33

their parents don't care about them

5:34

right because there is a mutation

5:37

the signal is broken the child cannot

5:40

control their diet that's what I started

5:44

studying um 30 years ago 25 years ago if

5:47

meeting what happened next in terms of

5:50

your academic journey I began to move

5:51

away from extreme obesity

5:54

to look at all body weight whether or

5:56

not you are skinny medium-sized or large

5:58

and secondly I also began to think I

6:01

can't just hide myself in a lab and do

6:04

this because otherwise there are going

6:06

to be people thinking that this kid's

6:09

fault that he is 100 pounds or someone

6:11

might be a BMI someone might be 10

6:14

pounds overweight and think it's their

6:15

fault as well

6:17

um that was for me a big turning point

6:19

to change what I was doing when I was

6:22

studying to make it more General

6:24

um and to also begin to do things like

6:27

uh to podcasts or to speak speak to you

6:30

and write books and do so do things more

6:32

broadly and speak to people outside the

6:34

academic environment and you've done a

6:36

number of shows on the BBC and

6:38

documentaries right I I I found three at

6:41

least

6:42

um the first one in 2016 called why are

6:45

we getting so fat in 2017 clean eating

6:48

the dirty truth and in 2018 vitamin

6:51

pills Miracle or myth

6:53

and obviously as well you've written

6:55

these two fantastic books called why

6:56

calories don't count and Gene eating

7:00

so my question becomes why why did you

7:02

focus on food why did you care

7:03

personally enough to pursue with such

7:06

persistence the topic of food why is

7:09

that personal to you could have done

7:10

anything with your with your

7:11

intelligence why food

7:13

so well first of all I love food so so

7:16

does that I do I do love food but

7:18

actually no we followed the biology so

7:20

we now understand more broadly that when

7:23

we study the genetics of body weight we

7:25

are by its very definition studying the

7:28

genetics of how our brain influences our

7:30

feeding Behavior so there was an

7:32

academic reason for uh um for this so

7:34

just as an example why do some people

7:36

respond to stress by eating whereas

7:40

other people respond to stress by not

7:42

eating it's exactly the same hormone but

7:44

people literally respond in diametric

7:46

opposite Fashions okay why do people

7:49

love food some people use food as fuel

7:51

etc etc and so on my academic side I

7:54

began to try and understand the

7:55

mechanisms I was interested in that but

7:57

then it got me thinking about food it

7:59

got me thinking well hang on a second

8:01

when I travel just as an example

8:04

um particularly pre-covered and I end up

8:06

in an airport somewhere International

8:08

O'Hare in Chicago or something like that

8:10

and I'm transferring planes for whatever

8:12

reason I have to I find myself having I

8:17

get stressed a little bit I find myself

8:18

having to eat a big bowl of carbs

8:21

particularly rice or noodles and I was

8:23

thinking about this this became a habit

8:25

whatever airport I'm in particularly if

8:27

I was transiting I would try and find

8:28

the closest place I could get a big bowl

8:30

of noodles in fact just before I came

8:32

here what I had for what I had for lunch

8:33

I went to Bone Daddy's to have Ramen so

8:36

so that's exactly that I wasn't no I

8:38

wasn't stressed but but I was trying to

8:41

relax okay and so that was what really

8:44

got me into I said well hang on a second

8:45

what is it about food that makes me

8:49

relax and calm and that I love and then

8:53

what is it about food that makes some

8:55

people so angry you know we're almost

8:58

religious almost Evangelical about it

9:00

and that is where I started thinking

9:02

there is a link here between what I do

9:05

in my day job in the lab and I teach and

9:07

I and what have you and what I think

9:10

about you know from broadcasting from

9:12

writing and that is when I said you know

9:15

if I'm going to do something I want to

9:16

enjoy it I love food I research food I I

9:20

you know I write about food that's the

9:21

reason why because because I love it and

9:23

I thought that it was an I wanted to

9:25

know more about myself and hence then

9:28

more about other people as well your

9:29

reference to a day job there what is

9:31

your day job as we sit here today so my

9:34

day job is I'm a professor at the

9:35

University of Cambridge and I teach and

9:37

I research there so that's my day job

9:40

um and I have a I have a group and we

9:41

study how the brain controls food intake

9:43

through using cells using molecules so

9:46

that's the day job I say that I mean

9:48

this is obviously I mean the writing is

9:51

is also a job obviously but it's it's

9:53

what I do in my spare time and actually

9:57

what's interesting is it's what has made

10:00

me I think a better scientist I think

10:03

too many scientists

10:06

lose perspective and that no that's fine

10:08

right I mean I mean I'm not more

10:10

brilliant than than they're many more

10:12

much more brilliant people than me but I

10:14

think people do lose perspective and I

10:16

think you need to go out out of the lab

10:18

you need to speak to do you need to ask

10:20

what people are interested in in a

10:22

broader broader Society what they

10:24

understand about what you do and so

10:26

that's that that's the reason why I do

10:28

what I do and why I say the day job

10:30

versus this even though I merge it all

10:31

together you've been studying food

10:34

genetics these topics for almost three

10:36

decades is that accurate since 1998 25

10:39

years okay

10:41

where are we in terms of culture

10:44

um as it relates to our opinion and

10:48

perspective on food you know what I mean

10:49

by that like if you started 25 years ago

10:52

when you observe how Society views food

10:56

the relationship it has with it versus

10:58

your perspective today where are we

11:00

today

11:02

I think it depends I I think there is a

11:06

polar response to food but we are in a

11:09

polarized Society we're living today and

11:11

I think the same is true about food I

11:13

think I'm I would like to think there

11:15

are people who enjoy food who love food

11:17

we we watch MasterChef we watch cooking

11:19

programs we love the food you know we

11:21

everyone loves Nigella that kind of

11:23

thing but then equally I don't know of

11:26

the same number of people there are also

11:27

people who fear food okay now I study

11:33

obesity I do study obesity

11:36

um and I know that most of the

11:39

non-infectious diseases we suffer from

11:41

today is because of poor diet most of it

11:43

obesity diabetes high blood pressure

11:45

certain heart diseases cancers Etc okay

11:48

this is true and so undoubtedly we need

11:51

to know more about our diet and we need

11:53

to fix the diet that we actually do it

11:55

but I don't do it through fearing food I

11:57

do it about understanding food about

11:58

loving food about learning how to cook

12:00

food better sourcing better food that

12:01

kind of thing right whereas there are a

12:04

lot of people in society who are talking

12:07

about restriction of food removing

12:10

entire food groups

12:11

um saying that this is the only way to

12:13

eat if you don't eat this way it is the

12:15

not the right way

12:17

um so I think we are in a polar

12:19

situation where in one on the one hand

12:21

we cannot consume enough food uh tallies

12:25

and cookbooks and and everything but yet

12:28

there is a huge section of society that

12:30

fears food so much that they that diet

12:33

has become this toxic word whenever we

12:35

talk about diets so I think that's where

12:37

we are at the moment we are in a polar

12:39

situation I read I read this word over

12:41

and over again in your work called

12:43

orthorexia what does orthorexia mean so

12:47

orthorexia is

12:50

a type of eating disorder people would

12:52

have heard of anorexia okay people would

12:55

have heard of bulimia

12:57

so anorexia clearly is a is a

12:59

controlling thing where you don't want

13:00

to eat bulimia is there's the binging

13:02

and there's the purging orthorexia is a

13:05

fear of not eating properly

13:07

it is another

13:09

I think it's an look I'm not a

13:11

psychologist and and a psychiatrist and

13:13

I'm not an eating disorder expert but I

13:16

think it stems from the same and from

13:18

the same root there is an there is an

13:20

effort to con wanting to control

13:22

something that you feel like you need to

13:24

control some people try and control

13:25

their diets other people pick something

13:27

it doesn't have to be I mean

13:30

you could say I want to be vegan or

13:32

plant-based or I want to be keto or I

13:34

want to do Carnival whatever it is you

13:35

want to do but then you become so hung

13:37

up on it that if it's not exactly

13:39

perfect if it's not exactly like right

13:42

you don't eat it so that is orthorexia

13:45

where suddenly you have to have

13:48

the burger but it's only cooked this way

13:50

it is a for lack of a better term it is

13:53

a

13:54

analogous to obsessive compulsive

13:56

Behavior but specifically with regards

13:59

to the way you prepare and are willing

14:01

to eat that specific food

14:03

I read something

14:05

um in your first book about orthorexia

14:08

Gene eating I believe it was this book

14:10

um in chapter 10 where you cite a study

14:14

of hundreds and hundreds of

14:17

women that follow food eating accounts

14:20

on Instagram and I think the study

14:23

concludes that about 49 of the women

14:25

that follow food eating accounts or food

14:27

accounts on Instagram have

14:29

what you would describe as orthorexia

14:33

um which is startling because that's 50

14:34

that's half the half the population that

14:37

follow these Instagram accounts have

14:39

this fear of messing up with their diet

14:42

but if you look I mean Instagram I think

14:44

is a very interesting thing I mean first

14:46

of all I as far as I understand someone

14:48

may correct me if I'm wrong the majority

14:50

of Instagram users are female yeah I'm

14:52

I'm not still and actually the biggest I

14:55

think probably what what are the two

14:57

biggest Instagram

14:59

um uh styles that are that we talk about

15:02

food or you talk about Fitness those are

15:04

the two big things there's many other

15:05

things as well and you're absolutely

15:07

right when you actually look at in fact

15:09

if I look at my Instagram followers okay

15:11

just just when you go to the little

15:13

things 89 are women there is no reason

15:16

to follow I just want to point out

15:17

there's no reason to to follow me other

15:19

than the fact that I talk about diets

15:20

all the time 89 really I mean I mean I

15:23

think that so if you consider me and I

15:25

talk about food okay and suddenly I'm

15:28

some you you know Joe Schmo nobody from

15:31

Cambridge who just who writes about food

15:33

and 89 are women then what happens if

15:35

you actually begin to talk about diets

15:37

and and it is it's it's it's true and a

15:40

huge number of them

15:42

it's easy

15:44

you know I look I look at Instagram too

15:46

and clearly my pictures are going to be

15:48

a little bit blah but there's some very

15:50

very well curated Instagram pictures the

15:52

the food is beautiful the people are

15:54

beautiful

15:55

um and but that's the purpose right it's

15:57

it's sort of like a little advertisement

15:59

campaign but I think there are many many

16:01

people even though they know because

16:02

people know I'm looking at a curated

16:04

curated item which I think deep down

16:08

inside think that this could be real and

16:10

this could be them and I think when you

16:11

take people who are susceptible to this

16:14

obsessive compulsive who are susceptible

16:16

to eating disorders and you suddenly put

16:19

that in front of of someone that I think

16:21

you you it can be triggering for some

16:23

people for me I

16:25

my sort of confusion with food and

16:28

dieting and weight loss and all of these

16:30

things stems from almost getting too

16:32

much advice and I think if you hung

16:33

around on Instagram for long enough if

16:35

you hang around just for like maybe a

16:36

day or two you would hear so much

16:38

conflicting advice on what the right

16:40

thing to do is this diet paleo keto you

16:43

should eat these plants and not eat that

16:45

don't eat meat and you've eventually you

16:47

go

16:48

[ __ ] I can't eat anything you know if

16:50

you listen to that much advice you'll go

16:51

well I can't eat anything and that

16:53

stifles you to a point where you're like

16:55

you're eating lettuce but then you

16:57

realize you're like you know and it's

16:58

just what can I eat the more food advice

17:00

I've consumed the less confident I've

17:03

become and what I can eat interestingly

17:05

I think when I was naive and ignorant

17:08

I was happier in terms of the orthorexia

17:11

you described that like fear of messing

17:13

up on my diet

17:15

I I think that the the real answer is

17:18

this the reason there is so much

17:19

conflicting advice is because there is

17:22

no One Singular right diet I think

17:24

there's some general principles we can

17:26

probably agree with okay we probably eat

17:29

too much sugar we probably need to not

17:31

eat so much uh um we need to a little

17:33

bit less meat and we need to eat more

17:34

vegetables okay so look if I say those

17:36

three things is anyone going to and if

17:39

anyone going to argue with me no because

17:40

it's a it's it's and that's probably one

17:43

of the Gen some of the general rules

17:45

but if you then begin to apply it into

17:47

your own self then the problem with

17:50

eating the problem with eating is

17:52

everyone is an expert at eating by its

17:54

very definition you're an expert at

17:56

eating I'm an expert at eating long

17:57

enough for us to be sat here having this

17:59

conversation and so when I eat a certain

18:01

way and I look at someone else and

18:03

eating is a very visible thing every

18:05

it's an open event and not only that you

18:09

then see what the person looks like okay

18:11

then in your head and we are human

18:13

beings simple we are nothing but mammals

18:15

we think Red Berry poison blueberry lion

18:17

whatever right and so you look look at

18:19

that fat person eating he's eating

18:21

something and so we begin to judge other

18:24

people based on what we're talking about

18:25

and now the major issues most people

18:28

keep their mouth shut mind their own

18:29

business and eat and do what and do what

18:30

they're doing but then you get loud

18:32

opinionated people who go on to

18:34

Instagram and say that look at that

18:36

person they're eating the wrong way the

18:37

right way is the way I eat look at me I

18:39

have a six pack you know etc etc and I

18:42

think that's the problem so the reason

18:43

why the information is conflicting is

18:45

because There Is No One Singular right

18:47

diet so it is going to be conflicting

18:48

you have people have to find the right

18:51

diet for themselves not only

18:53

biologically psychologically but also

18:56

lifestyle wise because because if you

18:58

don't find the right diet for you you're

19:00

never ever going to be able to stick to

19:02

it and and Thrive from it because you're

19:05

just not so I think that is the major

19:06

problem that's my biggest message if

19:08

anything is there's no right diet so on

19:10

this on that point if there being no

19:11

right diet a lot of that I guess is

19:13

because we have genetic differences

19:16

that's one element of it there are

19:17

genetic differences let's start there

19:19

then with my genetic makeup yep

19:23

um how might there be differences in my

19:25

genetic makeup that make my relationship

19:27

with food and eating and weight loss

19:29

different from yours

19:31

oh okay I I probably don't have as good

19:35

an answer genetics does not have as good

19:37

an answer about why different people eat

19:40

differently aside from cultural

19:42

differences at the moment okay so so the

19:44

genetics the reason behind that is

19:47

because it's very difficult to

19:48

accurately determine what someone has

19:50

eaten in order to Do genetics

19:53

what we do know because we can actually

19:55

observe is how people of different

19:57

ethnicities have are susceptible to

20:00

different diseases so famously

20:03

um East Asian people people that look

20:04

like me South Asian people Indian

20:06

pakistanis uh bangladeshis cannot get as

20:10

large

20:11

bmi-wise before becoming at risk of type

20:15

2 diabetes right compared to white

20:18

people Polynesians famously okay who can

20:20

get pretty large before they actually

20:22

end up get getting diseases so that's a

20:24

classic example where this is why South

20:26

Asian people East Asian people have a

20:29

higher predisposition of diabetes even

20:31

though obesity is not particularly a big

20:35

thing in their um in in their cultures

20:37

but then you then begin to look at body

20:39

shape that does that does matter as

20:41

matter as well where do you put your fat

20:43

do you tend to put a fat on your bum on

20:45

your tummy you know what is your um how

20:48

tall are you how short are you and all

20:51

of these things which we can see

20:53

visually we we can see

20:56

um there are people who are then

20:57

susceptible or not susceptible to

20:59

specific diseases other things you can't

21:00

see okay why are African Americans for

21:04

example more likely to end up with

21:05

cardiovascular heart disease okay less

21:08

likely with diabetes whereas why are

21:10

Indians you know more and so did you

21:12

then begin to ask the question and there

21:14

we have genetics what about in terms of

21:17

um this obese Gene I read in chapter two

21:21

of your book that there is a gene for

21:23

obesity there are more than a thousand

21:25

genes for body weight the obese Gene in

21:28

chapter two which I talk about is this

21:30

leptin Gene is this Gene which lets your

21:33

brain know how much fat you have so

21:35

that's the exact Gene leptin is the gene

21:36

that I talk about in chapter two with

21:38

the obese it's called the obese Gene

21:40

because the mouse was called obese there

21:42

was a lack of imagination

21:43

um because the mouse was a naturally

21:46

occurring Mouse

21:47

um that that had a mutation in the same

21:49

gene scientists found out what that was

21:51

and then found out that it was conserved

21:53

in humans and that's where my boss

21:55

Steven ratley then came in and found

21:57

that that Gene was also mutated in in

22:00

some humans so that's the obese Gene

22:02

it's the it's the fat Gene fat Gene

22:05

meaning Gene from fat

22:07

that lets your brain know how much fat

22:09

you have and is that possible to to be

22:11

not just on or off but slightly

22:14

defective so some people can just get

22:17

a little bit more hungry than others or

22:18

is it a binary thing where it can be on

22:20

or off so leptin

22:22

for whatever odd reason

22:25

is pretty much binary so if you have a

22:28

little bit of it you're fine if you have

22:29

none of it you're not however there is

22:31

obviously there is obviously a pathway

22:33

leptin signals to the brain which

22:34

signals to something else and there is a

22:37

another Gene that I looked that I looked

22:39

at called mc4r

22:41

it's part of the pathway it's part of

22:43

the same fat sensing pathway that is a

22:46

rheostat it's like a thermostat and so

22:48

for example we have found thousands of

22:51

different mutations in this in this Gene

22:53

and you can imagine that depending on

22:55

the severity of the dysfunction some are

22:58

completely dead some are 70 functional

23:00

you we can predict

23:02

how much someone will eat in a test

23:05

Buffet meal scenario

23:07

um if they have a 50 functioning Gene

23:10

versus a zero functioning Gene and we

23:12

now know that point three percent

23:16

okay in this country at least so point

23:18

so 200 000 people in the UK a million

23:21

people in the United States will carry

23:23

mutations in this mc4r Gene okay making

23:26

them more likely to end up with obesity

23:28

so that at 18 years old at 18 years old

23:31

if you carry a mutation in this nc4r

23:34

Gene you are on average

23:36

18 kilos heavier 40 pounds heavier at 18

23:39

years old on average and that's 200 000

23:42

people in this country so it's it's not

23:43

super common right it's still 99.7 of

23:47

the people's body weights not determined

23:49

by this but there are a lot of people's

23:51

body weights who are dependent on this

23:53

specific Gene but it is a it is a

23:54

tunable system so it's a little bit or a

23:56

lot means that you're either slightly

23:58

heavier or a lot heavier to does our

24:01

brain like us losing weight I I did the

24:05

keto diet recently for about two months

24:07

and why did you do it why'd you come off

24:10

I did it because I wanted to okay this

24:13

is interesting it shows how much of a

24:15

neanderthal I am

24:17

um I I thought I was allergic to gluten

24:20

hey so I thought I'll cut out all of the

24:23

things that have gluten in them and I'll

24:25

try that and so I then watched this

24:27

video online and it talked about the

24:29

keto diet so I thought oh that sounds

24:31

good and I this guy had lost so much

24:33

weight doing it so I gave it a try now I

24:35

lost so much weight more weight than

24:37

I've ever lost in my life like I extreme

24:41

um I did it for about eight weeks I lost

24:44

about a stone in weight the reason I

24:46

came off it

24:47

was because it was hard it was hard in a

24:51

in a simple word it was difficult and I

24:54

I don't know I felt like I was fighting

24:56

against something

24:58

how long ago did you come off it and the

25:00

crucial information piece of information

25:02

I'm interested in is have you gained any

25:04

weight back

25:06

um 45 days ago none of your business I'm

25:08

joking

25:11

no um I gained so much weight back I

25:14

gained I didn't just gain the stone I'd

25:16

lost I think I gained a little bit more

25:18

back I think I gained a stone and a bit

25:20

back uh I mean I'm not in bad shape but

25:22

like for me I went from being absolutely

25:25

lean like I'm ready for Men's Health to

25:28

being like back to being like you know

25:30

like um I'd say athletic now but I

25:33

gained back the way I lost and more

25:36

so this is why I asked the question

25:38

about the brain my brain didn't seem to

25:40

be on board with me it didn't seem

25:42

taught the best for us and it seemed to

25:45

want to return me back to my

25:48

default base state

25:50

your brain everyone's brains hates it

25:53

when they lose weight it doesn't matter

25:55

your starting point you could start from

25:57

a point where you are Athletic versus

25:58

someone who's not athletic Couch Potato

26:00

type type phenotype the moment you lose

26:03

a little bit of weight we're talking

26:04

even a few pounds I'm not even talking

26:06

you're talking about a stone even if you

26:07

lost five pounds what happens in your

26:10

brain is your brain is used to you

26:12

carrying you or me carrying a certain

26:14

amount of weight the moment your weight

26:16

starts to go down as an adult it goes

26:19

hey oh you know this is a big flag comes

26:21

up this reduce this is reducing my

26:24

chance of survival this is what the

26:25

brain thinks and so what it does is it

26:28

begins to use strategies not conscious

26:32

nothing to do with our brain anything

26:33

like that to drag us back up Kicking and

26:36

Screaming to where we were before first

26:38

of all it makes us hungry okay so so it

26:40

makes us it makes us hungry and second

26:42

it actually very very secretively lowers

26:45

your metabolism ever so slightly so that

26:48

even without think even eating exactly

26:50

the same thing you are now storing more

26:52

than you're burning even eating exactly

26:54

the same thing part of the strategy to

26:56

get you back up to where you were before

26:59

so once you were on that keto diet and

27:01

we can debate how it talk about how it

27:04

works and whether it's useful but once

27:06

it's on the you're on the diet your

27:08

weight goes off you're able to keep it

27:09

but you said man I can't do this and so

27:12

you stop and the moment you stop your

27:13

brain goes comes back on and starts

27:16

dragging you back up this is going to be

27:17

true for pretty much every single diet

27:20

that is that is out there the moment you

27:22

stop the diet

27:23

the weight will come back on eventually

27:25

why does my brain hate me

27:27

it's what look this is the brain you

27:30

have to remember

27:31

um that that's what's kept us alive I

27:33

mean we have lived aside from probably

27:36

the last 40 years

27:38

we probably most of the time never had

27:41

enough food now clearly over the past

27:44

hundred years we've had sufficient food

27:45

compared to beyond that but you know as

27:49

well as I do when you turn on the TV and

27:51

watch Only Fools and Horses from the

27:52

from from the 70s or whatever you know

27:54

people are all skinny they think oh no

27:56

they're not skinny they don't look

27:57

skinny they look they look normal weight

27:59

for the time that they're that they're

28:00

there whereas we have clearly over the

28:03

past 40 years now have too much food so

28:05

this is now a different problem okay

28:07

that we have too much food and so our

28:11

brain is trying to respond to this

28:13

environment but it's responding in a

28:15

natural fashion because what used to

28:17

happen was because there was not a food

28:19

when there's food there you made sure

28:21

you ate it otherwise why would you why

28:23

would you not do that right so

28:25

we have a brain that's wired for a feast

28:29

famine environment Feast fam and feast

28:31

famine the problem is we live in a feast

28:33

Feast environment at the moment and

28:35

that's the issue we have a mild adopted

28:37

brain for a feast Feast environment and

28:40

this is because of how you set up

28:41

Society because of supermarkets fridges

28:43

preservatives that keep food lasting for

28:46

longer and Foods more available and

28:47

cheaper than before it's more processed

28:50

Etc right so so this is true now now

28:52

without going all food Nazi I mean you

28:56

have to remember that the all of

28:58

whatever you just said preservatives you

29:00

know pickling cooking you start with

29:03

that then you say oh we're gonna do

29:05

highly processed foods we're going to do

29:06

pre-packaged foods frozen foods

29:08

microwave Foods etc etc supermarkets it

29:10

has kept us alive okay we're seven and a

29:13

half billion people and Counting we need

29:14

to feed all these people and this is

29:16

fine the problem is we've now got to the

29:20

point where the efficiencies the scales

29:23

of efficiency and how fruit production

29:25

is now so high we can now get calories

29:28

have never been cheaper so this is this

29:30

is the

29:31

um the the the the the issue today you

29:35

can on uh um in this country for example

29:37

in the UK people have calculated that

29:39

you can get about a thousand calories

29:41

for 90p now how good are those calories

29:45

what the quality of the food or those

29:46

calories we're not talking we're just

29:48

talking pure calories because of

29:50

efficiencies of scale calories have

29:52

never been cheaper and we don't have to

29:53

go run after an antelope in order to get

29:55

in order to get the calories this has

29:57

kept us alive until it is killing us

30:00

which is now over the past 10 years that

30:03

have been an important inflection point

30:05

in in human history you know previously

30:07

we never had enough food whereas now

30:09

since the the past 10 years more people

30:12

are dying from over nutrition

30:15

than under nutrition and over nutrition

30:18

in a bad way because you can be you can

30:21

have loads of calories but still be

30:23

malnourished because you're eating the

30:24

wrong kind of foods and can you believe

30:25

it we are now in a world where there are

30:27

more people dying because they eat too

30:29

much than because they because they

30:31

don't eat enough is the worldwide Trend

30:33

that we are getting

30:34

skinnier or fatter we are getting fatter

30:37

as a worldwide Trend and and and true

30:40

that the the problems are more obvious

30:42

at the moment in higher income countries

30:45

okay because

30:46

because either they studied more and be

30:49

the kind of food that's available but

30:51

you are good but what is the goal of of

30:55

um of a country that is less developed

30:57

than us for example they want to pull

30:58

their people out of poverty they want to

31:00

make sure that their poor people don't

31:02

die of starvation they want to make sure

31:05

that fast food and and good food you

31:09

know and crab food are available to

31:11

everybody uh there as well now the

31:13

problem is the moment that happens you

31:14

don't switch from being dying of under

31:17

nutrition and starvation to then now

31:20

dying of over nutrition so we are at

31:21

that infection point where the whole

31:23

world very soon will get into a severe

31:27

obesity problem and and we do need to

31:30

fix the food environment in order to fix

31:32

that do you consider it to be an

31:34

emergency it is definitely an emergency

31:36

oh it is definitely an emergency and

31:37

it's an emergency because because

31:41

let's ask the question why is it a

31:44

problem to have obesity why is it a

31:46

problem to carry too much fat okay so so

31:48

that doesn't you might think well it's

31:49

obvious well is it because the the there

31:53

are issues with gravity when you're too

31:55

heavy um arthritis Mobility sleep apnea

31:58

you can't breathe at night but that is

32:00

that isn't what kills us okay if what

32:02

kills us is all the diseases that are

32:04

associated with obesity diabetes high

32:07

blood pressure certain cancers etc etc

32:09

that is what kills us okay heart disease

32:12

and and so it is an emergency because

32:14

with obesity at a population level as it

32:17

goes up then you have millions upon

32:20

millions of people

32:21

um that that end up you you know with

32:25

diseases so the the estimate is that

32:27

direct cost to the NHS direct costs for

32:32

treating obesity and related illness is

32:34

six to seven billion a year okay pounds

32:37

that's the direct but the moment you

32:40

take into account the bro economy days

32:42

sick

32:43

etc etc it's estimated we are running at

32:46

27 billion a year just on economic

32:49

effects on on Obesity so it is an

32:52

emergency because because many people

32:55

are getting ill many people are dying

32:57

you know

32:59

and actually it makes economically no

33:01

sense we have to fix the Obesity because

33:03

then we would save ourselves a lot a lot

33:05

of money so let's talk about how we fix

33:07

the Obesity how we burn fat and how we

33:10

all get into a healthy weight now I know

33:13

you think that bmis are largely [ __ ]

33:16

and unhelpful is that an accurate

33:18

description of your opinion

33:19

okay look before I I don't want to end

33:22

up um with my colleagues throwing shoes

33:24

at me so I think

33:25

awesome so BMI for those of you who

33:28

don't know BMI is obviously

33:30

um your weight in kilograms divided by

33:33

your height a meter Square it's a way of

33:34

controlling for your height and your

33:35

weight

33:36

um now on a population level okay it is

33:40

actually a remarkably effective why

33:41

because a it's free to measure it

33:43

doesn't cost anything

33:45

um and on average in a population sadly

33:48

um the higher your BMI the more fat you

33:50

carry and we know that the more fat you

33:52

carry the more likely you are to be

33:54

unhealthy okay on a population on a

33:56

population level all this is true you

33:58

might argue rugby players different this

34:00

and this is this is true

34:02

on an individual level however

34:04

it is not particularly useful for for

34:07

your for your health other than tracking

34:09

your weight it's about as useful as that

34:11

because each of us are different shapes

34:13

different sizes

34:15

can carry different amounts of fat uh

34:17

can carry different amounts of fat

34:18

safely so so that is the problem with uh

34:23

um with with obesity right it's it

34:26

depends on who you are

34:29

um how heavy is heavy before it actually

34:31

begins to actually influence your

34:33

influence your health

34:35

so let's talk about food a little bit

34:37

um I'm

34:38

currently

34:40

doing some kind of version of

34:42

intermittent fasting right detail

34:45

details version well I just don't let's

34:48

call it time restricted okay yep right

34:50

you know

34:51

um basically I don't I I don't have

34:53

breakfast I actually don't really get

34:54

hungry at breakfast to be completely

34:56

honest with you I tend to get hungry a

34:57

bit later in the day so I haven't eaten

34:59

anything today and God forbid uh it's 3

35:01

30 p.m

35:03

um wow I know but I just don't I just

35:05

don't seem to get hungry yet

35:08

um and then I read your book and in

35:11

chapter three of Gene eating you talk

35:14

about front loading your food in the day

35:17

now I was like [ __ ] hell you know I'm

35:21

trying my best here Giles and they told

35:24

me to eat later in the day to skip

35:27

breakfast we don't need it and then to

35:29

time restrict your eating and then I

35:30

read your book and then it says front

35:32

load your food have a big breakfast

35:34

medium lunch small dinner

35:36

what's the truth okay so so that is the

35:39

I mean I think most societies have a

35:42

similar saying the Chinese have a

35:43

similar saying as as this as well so

35:47

um a couple of things I was saying eat

35:49

like a king at breakfast a prince a

35:51

Princess lunch and a pauper at um at

35:53

dinner time and so the Chinese have have

35:55

a similar have a similar saying because

35:57

I think people kind of work this out now

35:59

there is some truth to this but then

36:01

I'll come back and explain what the

36:02

truth or the truth is so the sum truth

36:04

is that actually clearly we are

36:07

metabolically our metabolism is highest

36:09

during the day because we have to avoid

36:12

becoming food and we have to look for

36:13

food okay so so that's the thing whereas

36:15

at night when we're asleep our

36:16

metabolism drops so if you eat your

36:19

biggest meal at night

36:22

and then a couple of hours later you go

36:24

to sleep then clearly you you are

36:26

loading your calories and then going to

36:28

sleep which is in storage mode whereas

36:30

if you eat your biggest meal during the

36:32

day you have the whole day left in order

36:33

to burn it now homeostasis it does

36:36

balance itself out so it's not the

36:37

driver of obesity but undoubtedly it

36:40

will make a little bit of a difference

36:41

there okay but then a friend of mine

36:44

um Alex Johnstone Alexandra Johnstone

36:46

Professor Alexander Johnstone up at the

36:49

Robert Institute in in Aberdeen just

36:51

published the study I think probably

36:53

only three months ago okay which is very

36:55

interesting so what she did was she got

36:57

um people

36:59

um a cohort of people and got them to

37:01

eat exactly the same number of calories

37:03

they supplied the food so they knew what

37:04

they were going to do okay and they did

37:07

it either by front loading all the

37:08

calories at breakfast or back loading

37:11

all the calories at dinner but everyone

37:13

I ate exactly the same thing and then

37:15

everyone then swapped okay so everyone

37:17

did the did the whole thing and what she

37:19

found was that there was no different

37:22

reference in body weight change whether

37:24

or not you were eating most of your

37:26

calories at breakfast or most of your

37:28

calories at dinner it was the total

37:31

amount of energy during the day

37:32

but

37:34

the difference was if you ate more at

37:37

breakfast you felt less hungry during

37:40

the day

37:41

then you if you ate more at dinner so

37:44

while if you

37:46

ate exactly the same Foods thought at

37:49

breakfast or dinner dinner or lunch it

37:51

doesn't actually matter but for some

37:53

people it may very well be easier to

37:56

have the big breakfast because it means

37:57

particularly if they love food in

37:59

particular because it means they get

38:00

less hungry throughout the day so that

38:02

is the truth that is the Nuance but does

38:04

that mean you know I've got a first-hand

38:07

experience in this that if I'm not

38:09

hungry throughout the day then when it

38:10

gets to midnight

38:12

I'll be thinking Hmm no but it doesn't

38:14

matter right because because it's not

38:16

like it's not like well it depends

38:17

depends how much if you suddenly ate

38:19

3000 calories at dinner then then then

38:21

maybe they're no I'm not talking dinner

38:23

I'm talking midnight snack

38:26

so I I think the reality the the reality

38:29

is you have to eat when you have to eat

38:32

uh is is the answer now if you were

38:35

trying to lose weight so if you were

38:37

actively trying to lose weight because

38:38

you are active because if one was

38:40

actively overweight then you might begin

38:42

to think about when you wanted to eat

38:44

more I would probably cut the calories

38:46

from your dinner rather than cutting the

38:48

calories from your breakfast but if you

38:50

are surviving during the day and this is

38:52

true about many people right nurses

38:54

doctors who work shifts firemen police

38:56

police officers whatever they do you've

38:58

got to eat when you gotta eat so these a

39:00

lot of these um pieces of advice are

39:03

fine until they smack into the reality

39:07

of Life your job and what you actually

39:09

and what you actually do but it's

39:10

general advice for the general person

39:12

who isn't constrained by night shifts or

39:14

anything like that eating late

39:17

closer to when you fall asleep is bad is

39:20

not going to help you lose weight

39:22

correct okay everyone says this you know

39:26

Tim Spector said this to me I need I

39:28

need people to keep saying it and then I

39:30

will cancel the midnight Buffet

39:33

but I love my midnight Buffet too yeah I

39:36

know but every so often only not every

39:37

night yeah yeah not all the time you

39:39

know five nights a week

39:41

um

39:42

your general stance on keto you know

39:45

much of your feedback and much of your

39:47

writing is more about how it's

39:48

unsustainable

39:50

um is that is that accurate well it

39:53

depends so so the original keto diet

39:55

keto in its original form was oddly

39:58

enough it was designed for epilepsy okay

40:01

that was what it was originally designed

40:03

to do it's only in its most I would say

40:05

the past 10 years that suddenly people

40:07

have realized there was a weight loss

40:08

element to it as you as you personally

40:10

firsthand uh actually actually found it

40:12

so I think the original versions of Keto

40:15

were actually very very very

40:17

unsustainable because of the really

40:19

super high levels of fat that were

40:22

involved they were unpalatable and and

40:24

and and with absolutely almost zero

40:27

carbs they were very unpalatable they

40:29

they're difficult to stick to if you

40:31

have inflammation related diseases is

40:32

keto often a diet that's recommended if

40:35

there's like inflammation related

40:37

depends it depends where the

40:38

inflammation is so so if it's

40:40

information in a gut you need a

40:41

different type of diet is so so that

40:43

there is no one for a given information

40:45

right so it then it depends on the diet

40:47

that you're actually actually own but

40:49

keto in this extreme form is difficult

40:51

to stick to because you know because of

40:54

the really really high fat to protein

40:56

ratio so it was designed for epilepsy

40:58

because I think there was some reason

41:01

just to say that when you force your

41:03

brain to use ketones which is rather

41:06

than glucose which is where the keto

41:09

diet comes from it reduces the incidence

41:11

of epilepsy so leave that aside but what

41:13

then people found as well is that with

41:16

the keto diet you ended up feeling

41:18

Fuller

41:19

and so more satiated and so therefore

41:21

you lost weight because you ended up

41:22

eating eating less weight sorry eating

41:24

less food but also because you were

41:26

having less carbs then it was easier to

41:29

control your blood glucose so keto I

41:32

think is probably good

41:34

safe thing for some type 2 diabetics

41:37

looking to try and a milder form of Keto

41:40

because now there's different types of

41:41

Keto that you can stick to to try and

41:43

control your blood glucose if you're

41:44

type 2 diabetic

41:46

just make sure you don't eat

41:49

as much of the fat as animal fat trying

41:51

to have more olive oil and fish fat and

41:53

vegetable fat rather than animal fat

41:55

then there probably is a case to be made

41:57

for for for keto not as extreme for a

42:02

healthy uh individual such as yourself

42:04

you found how difficult it was to

42:06

actually stick to it I think that's

42:07

probably a case to be made for

42:09

introducing a little bit of

42:10

carbohydrates but high fiber

42:12

carbohydrates in there so that makes it

42:14

more sustainable

42:15

the issue is and I think one needs to be

42:17

careful is certainly in its most extreme

42:19

forms they haven't been many studies

42:21

looking at the safety say over five ten

42:24

years if you stick to keto all the time

42:26

how healthy is it for you and so that's

42:29

the only

42:31

um caveat that I want that I want to

42:32

point out the studies need to be done as

42:34

it becomes more popular the studies will

42:35

be done because there are many people

42:37

millions of people who swear by keto and

42:40

um and inherently as long as you don't

42:43

eat too much animal fat only and so you

42:46

have vegetable fat and fish fat and

42:47

olive oil and things as well then it can

42:50

be relatively healthy

42:52

you reference there that

42:55

um the protein makes you feel Fuller

42:58

that's that seems to be a really

43:00

important point that if you have a high

43:01

protein diet you're going to end up

43:04

eating less which will result in weight

43:05

loss right in what order does like

43:08

protein fats and carbohydrates make you

43:10

feel fullest

43:12

so a calorie of protein makes you feel

43:14

Fuller than a calorie of fat than a

43:16

calorie of carbohydrate in that order so

43:19

and and the reason behind that is

43:21

because protein is chemically the most

43:24

complex compared to fat and carbs

43:26

so so it takes the longest to a digest

43:29

and be metabolized so and because it

43:31

takes the longest any food which travels

43:34

further down the gut

43:35

makes you feel Fuller that's just a

43:37

general it's a it's a general

43:39

um um thing of how how our body works

43:42

so that's the first thing so protein

43:44

takes longer to digest travels further

43:45

down the gut you feel Fuller but then

43:47

not only that protein gets digested into

43:49

amino acids amino acids transfer across

43:52

the gut wall into our blood and they

43:55

again go to our cells and organs where

43:56

they then metabolized now during the

43:59

metabolism stage it then takes a lot of

44:02

energy to metabolize protein compared to

44:05

fat and carbs so for example

44:07

for every 100 calories of protein that

44:10

you eat

44:11

we are only ever able to use 70 calories

44:14

so 30 of the protein calories we eat

44:18

are spent dealing with protein it takes

44:21

money to make money right and so at 30

44:23

so protein calories everywhere this is

44:26

not reflected on the side of the package

44:27

protein calories everywhere are 30 wrong

44:30

just off just just just off the bat

44:31

because of the amount of energy it

44:34

actually takes to sort out to sort out

44:35

Protein that's another reason why it

44:37

makes you feel Fuller

44:38

super interesting that point about

44:39

calories obviously I talked to Tim

44:41

Specter a lot about that and um it

44:43

really is a kind of a narrative Buster

44:45

that calories are not accurate

44:49

so look I I I I speak a lot about

44:52

calories I understand that 200 calories

44:55

of chips is twice the portion of 100

44:58

calories of chips

44:59

but so is 200 grams of chips twice the

45:01

portion of 100 grams of chips and no one

45:04

is trying to compare 200 grams of chips

45:06

to 200 grams of carrots broadly speaking

45:08

that's what it is the calorie is a very

45:11

useful tool

45:13

um to give you a general idea how much

45:16

you are eating during the day that is

45:17

true okay how much you're eating but it

45:20

tells us nothing zero about the quality

45:23

of food you're eating about how much

45:24

protein how much fiber what type of fat

45:27

how much sugar the calorie tells you

45:29

absolutely nothing so it gives you a

45:32

piece of information how much food

45:34

you're eating and that's yes I can see

45:35

how that could be important but I would

45:39

like to see a world we live in where we

45:41

were more concerned about the quality of

45:43

food we are feeding ourselves our kids

45:44

other people they're necessarily just

45:46

the pure caloric content because I've

45:48

got a friend that said to me won't name

45:49

him but he got a friend that said to me

45:51

that um you can basically as long as you

45:53

count the calories you can eat whatever

45:54

you like so you can have the Domino's

45:56

Pizza you can have this but you just

45:59

gotta make sure the calories are under

46:00

your sort of calorific allowance and

46:03

then it's it's all good

46:05

so now if your depends what your

46:08

calorific allowance is and it will

46:10

clearly if you stick to a purely calorie

46:13

counting diet

46:15

of say 2 000 calories and you stuck to

46:18

that religiously okay you probably the

46:21

chances are you probably would lose

46:22

weight because we probably burnt burnt

46:24

more than that but how healthy would you

46:26

be I think is probably the question

46:27

whereas if you had a healthier diet but

46:31

a 2 500 calories of a healthier diet

46:34

would you would you be healthier and

46:37

that's that's the more important

46:38

question I think you've asked because

46:39

there's two things you're trying to look

46:40

at you're trying to look at the number

46:41

on the scale and that probably would

46:43

work or you're trying to look at your

46:45

health your blood glucose levels your

46:47

blood pressure your ability to be

46:49

energetic during the day you know how

46:51

fast you want to run whatever it is

46:52

whatever metric can you lift your

46:53

grandkids up whatever you want to do and

46:56

so I think it's a it's a it is a measure

46:59

clearly it is I'm not I'm not denying it

47:01

that it is not a measure but it is a

47:03

very blunt tool and I don't think it is

47:06

measuring what we need to measure which

47:07

is the quality of our food what is

47:09

calorific availability in fact reading

47:12

your work is the first time I've even

47:13

heard that phrase before but it seems to

47:15

be to be important so calorific or

47:18

caloric availability is the amount of

47:21

calories that you can extract from a

47:24

food versus the total number of calories

47:26

in a food so the example which I cite in

47:29

in both books actually is if you had 100

47:31

calories of sugar just just pure white

47:34

sugar you would probably end up getting

47:36

98 nearly 100 calories out of it nearly

47:39

100 okay because sugar is our base fuel

47:42

we chop once we absorb it there's no

47:43

digestion that's involved the one

47:45

example which I give is imagine if you

47:47

ate sweet corn corn on the cob

47:50

and then you looked in the loo the next

47:51

day it is quite clear you haven't

47:54

absorbed most of the sweet corn because

47:56

you can see it okay but if you take

47:58

sweet corn desiccated convert into

48:01

cornmeal make cornbread or corn tortilla

48:03

do something else with it suddenly

48:05

exactly the same source of food gives

48:08

you a different amount of calories okay

48:10

but yet it starts on corn it's exactly

48:12

the same thing so that's caloric

48:14

availability you can start with a

48:15

sourced food but depending on what you

48:18

do to that food different calories are

48:20

available there's nothing wrong with

48:22

cuantotia there's nothing wrong with

48:23

cornbread and there's nothing wrong with

48:24

sweet corn I'm just saying that the

48:26

calorie counts make no sense because

48:30

you will extract different amounts of

48:32

calories from the food even though we're

48:34

working with exactly the same food

48:36

that's crazy so if I I had um call on

48:39

the cob

48:41

like you I'm just mimicking your action

48:43

there um and then I had a corn tortilla

48:46

yes if both of them sell in the package

48:48

this is a hundred calories the truth is

48:51

my body might with the corn on the cob

48:54

only have

48:56

50 of the calories available because of

48:59

the

49:00

the nature of the the food versus if I

49:03

had the corn tortilla Which says 100

49:05

calories in the package as well

49:08

I might get 80 calories from it yes

49:11

so so let me give you another example

49:13

celery is probably something that's easy

49:14

and and we've actually measured this so

49:16

if you actually look at a just a typical

49:18

medium-sized stick that you might get

49:20

with some buffalo wings or something

49:21

like that okay of of celery raw okay

49:25

people say that celeries have an uh has

49:27

a negative calories not really but it's

49:29

got only six calories it's nearly

49:30

negative okay for that if you cook the

49:33

celery

49:34

chop it up put into a stew whatever the

49:36

hell you're gonna do with it

49:37

that six calories becomes 30 calories

49:40

because you've cooked it exactly the

49:43

same food and this time I'm just cooking

49:45

it all right because the cooking you can

49:49

almost consider cooking as an extension

49:51

of your stomach it does some of the

49:52

digestion for you right because you're

49:54

cooking it but it's gonna even stew it's

49:55

just an hour two hours and then you eat

49:58

it so then all that energy the reason

50:00

why we only extract six calories from

50:02

from a raw celery is you know it's CR is

50:05

99 fiber and water and so you

50:09

whereas if you cook it then what happens

50:11

is some of the fiber breaks down we're

50:12

able to do it that's a class another

50:13

classic example exactly the same food

50:15

you cook it suddenly six times the

50:18

number of calories you get from it it's

50:20

an extreme example

50:21

exactly because I could go to a

50:24

supermarket and I could get a um

50:26

a six calorie stick of celery it could

50:30

literally say on the package six

50:31

calories I take it home I think great

50:34

I've got six calories left in my my

50:36

calorie deficit today I pop it in the

50:38

pan I stew it I eat it 30 calories out

50:41

of nowhere correct that's false

50:42

advertising correct

50:44

I'm gonna get myself into trouble no but

50:46

it's true that that is exactly that is

50:49

exactly true that's crazy that's why I

50:51

don't think that's

50:52

that's why I don't think calories are

50:55

the most useful thing to be to be

50:56

measuring because they shift they're

50:58

moving they're a moving Target which is

51:00

fine as long as we know what what what

51:02

we're expecting but to but if you are

51:05

religious calorie counter once again you

51:07

have to do you in order to so some

51:09

people do that and it's and for them it

51:11

is a useful strategy to keep the weight

51:13

off and be healthier I'm not going to be

51:15

back on you you do what you you do what

51:17

you want but you have to understand that

51:19

religiously counting it means that

51:21

depending on what type of calories you

51:23

eat that no matter how religious you are

51:25

you're going to be absorbing different

51:26

amounts of calories anyway

51:28

but again as you as you've highlighted

51:30

there the positive upside to that is it

51:32

gives people something to measure yes

51:33

which is relative yes and and that's the

51:36

benefit for them that if they're

51:38

measuring every day and it's the same

51:39

food they're measuring it's all relative

51:42

um and there's some benefit to them

51:44

because obviously people do are very um

51:46

passionate that they've had great

51:47

results from calorie counting in their

51:49

lives it's something to measure but most

51:50

people well many people who calorie

51:52

count just to be clear means they they

51:54

stick to eating the same thing which

51:56

they've done roast chicken whatever it

51:58

is but eat fewer calories of the roast

52:00

chicken dinner now that does work

52:01

because what you're doing is you're now

52:03

reducing the portion size of what you're

52:05

eating whereas if you're saying that

52:07

wait a minute I'm going to switch meals

52:09

entirely and go from eating 2 000

52:12

calories of chicken but I'm now going to

52:14

have 16 1 600 calories of sugar that's a

52:17

stupid example but imagine that was the

52:19

case okay then calorie counting is not

52:21

going to work because you could be

52:22

chicken is better for you than sugar and

52:24

and so and so that is an extreme example

52:27

but few people do that but I I

52:30

highlighted only to make sure people

52:32

understand it understand the limitations

52:34

and caveats of calorie counting quick

52:38

one one of our sponsors of this podcast

52:39

blue jeans recently did some research

52:41

and they found that almost a third of

52:43

companies are still spending almost a

52:45

quarter of a million a year on launching

52:48

and hosting virtual and hybrid events

52:49

this is obviously Bonkers with blue

52:51

jeans new software called events and

52:52

Studios you can host these professional

52:54

world-class feeling events for a

52:56

fraction of the cost so now going

52:59

forward for all of my companies and for

53:01

myself I think we did our last one in

53:03

telegram not so long ago every event I

53:05

will host will be hosted on Blue Jeans

53:07

events and Studios and I've never seen a

53:09

software tool that allows you to

53:11

personalize and brand and an interface

53:13

and the interface itself with such ease

53:15

that's the real thing about the the

53:16

software I've done I think two events on

53:18

Blue Jeans events and Studios the ease

53:20

of not having to be an expert to create

53:23

an unbelievable event if you've got an

53:24

event coming up if you've got a virtual

53:26

event coming up do me and yourself a

53:28

favor and check out blue jeans events

53:30

and Studios it's honestly incredible and

53:33

I'd love to hear your responses if you

53:34

do give it a try you know I never really

53:37

usually pick the chocolate flavored

53:39

heels my favorite are the banana flavor

53:41

I love The Salted Caramel flavor but

53:44

recently I think I in part blame Jack in

53:47

my team who's obsessed with the

53:49

chocolate flavor heals I've started

53:51

drinking the chocolate flavor heels for

53:52

the first time and I absolutely love

53:53

them my life means that I sometimes

53:55

disregard my diet and it's funny that's

53:57

part of the reason why I've had a lot of

53:59

guests on this podcast recently that

54:00

talk about diet and health and those

54:02

kinds of things because I am trying to

54:03

make an active effort to be more healthy

54:05

to lose a little bit of weight as well

54:06

but to be more healthy and the role that

54:08

he'll plays in my life is it means that

54:10

in those moments where sometimes I might

54:13

reach for

54:14

you know junk Foods

54:17

having an option that is nutritionally

54:18

complete that is high in fiber that is

54:21

incredibly high in protein that has all

54:22

the vitamins and minerals that my body

54:23

needs within Arm's Reach that I can

54:26

consume on the go is where he always

54:28

been a game changer for me

54:30

I started to believe I think as I said

54:31

you earlier maybe 12 months ago maybe a

54:34

bit more 24 months ago that I was gluten

54:36

free and I believed that because I I'd

54:38

eaten some things and then I had like a

54:40

bad gut reaction

54:42

um some pains bit of bloatedness and and

54:45

then when I didn't eat those things that

54:47

had gluten in them that kind of pain and

54:48

bloatedness went away so my genius brain

54:51

assumed self-diagnosed that I am gluten

54:55

intolerant and then I marched through

54:56

the world for the next two years being

54:58

that kind of like pretentious [ __ ]

55:01

that's asking if there's gluten and

55:02

everything and you know interrogating

55:03

the ingredients of everything I put in

55:05

my mouth to try and avoid this thing

55:06

called gluten

55:07

now from reading your work

55:11

I've started to consider that I'm not in

55:13

fact a genius that I'm in fact an idiot

55:15

and that I'm probably not gluten

55:17

intolerant

55:18

um and that because you look at society

55:19

and you look at packaging and you look

55:21

at signage on restaurants and on menus

55:23

they they have gluten-free everywhere

55:25

now everything is like gluten-free you

55:27

go in the supermarket aisles it's

55:28

gluten-free pasta gluten-free this

55:30

which creates the impression that where

55:32

humans are just not meant to eat gluten

55:33

and we're all gluten intolerant or 50 of

55:35

us are how much truth is there to that

55:37

so one percent of the human species are

55:40

celiacs okay and they are completely

55:43

allergic to gluten and and you don't you

55:45

want to stay away from gluten okay like

55:47

literally that's they get to the point

55:49

where it's so bad that their guts don't

55:52

work anymore and can't absorb food

55:53

carefully and so it can kill you so

55:55

that's no joke and so gluten-free was

55:58

originally designed to cater to people

56:00

with celiac disease one percent of the

56:02

human species now three to four percent

56:05

of humans and they're slightly more

56:08

difficult to measure are probably

56:09

genuinely gluten intolerant and this

56:12

could be maybe from a little bit farty

56:13

till some severe gastrointestinal

56:15

distress

56:17

um and but genuinely so and probably

56:19

it's best for them to at least not have

56:21

a big bolus of gluten but the rest of us

56:23

are not but yet 25 as a as a market 25

56:27

of us buy gluten-free at any one point

56:30

so it's become profitable to sell

56:33

gluten-free they now label rice as

56:35

gluten-free rice doesn't have gluten

56:36

never had gluten okay okay okay from

56:39

from it and so they label rice as

56:41

gluten-free thinking that it's some

56:42

product it's not a product it's just

56:44

rice

56:44

so I think the issue here is it's been a

56:48

boon for people with celiacs uh for

56:50

celax I've spoken to people with celiac

56:52

disease they go we've never had it this

56:55

good okay because before you have to go

56:57

you have to be really concerned now

56:59

every place you go to the moment you say

57:02

gluten-free you get a gluten-free meal

57:03

and everything and everything is fine

57:04

the only downside is some people look at

57:06

them you know but but so but that is a

57:10

classic example of of people

57:15

thinking that it's healthy but can I

57:17

just once again I'll stop asking you a

57:19

question soon but

57:20

did you actually go and get yourself

57:21

diagnosed about whether or not you are

57:23

gluten intolerant because it doesn't

57:25

mean that you're not because you could

57:26

be

57:27

by the way you can always ask me

57:28

questions and to answer your question

57:30

yes I got diagnosed by Dr Stephen

57:31

Bartlett right

57:34

in the comfort of my own home

57:38

but my brain my brain wrote out the slip

57:41

and made the diagnosis have you gone

57:43

back to eating some gluten yes and

57:45

nothing has happened you know what's

57:47

really interesting something after I

57:49

finish the keto diet yeah fad uh keto

57:53

diet I then tried a little bit of gluten

57:55

and everything was okay

57:58

it was it was I had a little bit of

58:00

glutes in it I didn't really notice any

58:01

any issue so and I was wondering if like

58:04

keeping myself off gluten or keeping

58:07

myself off something for those two

58:09

months had almost restored my my gut in

58:13

some respect that I could have a little

58:14

bit of gluten again

58:16

because I I kind of I don't know

58:18

it was interesting but the issue with

58:21

gut is that many so for example I will

58:24

have exactly the same symptoms of what

58:26

you just said bloated blah blah all

58:27

these things when I have lactose I'm

58:29

lactose intolerant because it is

58:32

a food substance that influences the gut

58:35

so I think the issue is I wouldn't

58:37

put out of hand some thing which you've

58:40

had with your gut it could be actually

58:42

real is it necessarily gluten was it uh

58:45

was it lactose was it something else so

58:48

so the problem is and the reason why

58:50

people immediately think gluten is

58:51

because that's what's in front of them

58:52

but it could be a number of other things

58:55

which cause your gut just for a little

58:57

bit or you could just reading the wrong

58:58

type of chilies right and and and that

59:01

that could also do it but the moment it

59:02

begins to influence your guts it has

59:04

broadly speaking the same phenotype same

59:06

the same presentation whether it's

59:08

gluten lactose or Mexican chilies so

59:10

that's that's interesting so you're

59:12

saying you know one to four percent of

59:14

people really do have an intolerance

59:16

roughly yes and then 25 ish percent of

59:20

us buy gluten-free assuming we are you

59:23

know I either assume you are gluten

59:25

intolerant or think it's healthier I

59:27

don't think it's healthier okay we think

59:28

gluten's a bad thing yeah is gluten a

59:31

bad thing if you can handle gluten no if

59:33

you eat too much of it that's always a

59:35

bad thing but no and let's put it this

59:37

way as as a gluten-free donut is still a

59:40

donut

59:41

whether or not it has gluten or not you

59:43

know so there are things which are

59:44

inherently fried and and are have more

59:47

calories more caloric availability and

59:49

there are things which are inherently

59:50

less whether or not they have gluten

59:52

what about you said you said lactose

59:54

intolerance then you're lactose

59:55

intolerant and in your book you say that

59:57

65 of adults are lactose intolerant

60:01

that's correct that's crazy that's a

60:03

huge huge majority that's a huge

60:05

majority because the mutation

60:08

is lactose tolerance so and so under

60:11

normal circumstances so lactose is a

60:13

sugar like glucose like fructose

60:16

but mammals obviously all mammals can

60:19

drink milk as babies we are mammals

60:22

um all mammals can obviously drink milk

60:23

and absorb lactose as babies but then

60:27

most mammals including 65 of human

60:30

beings become lactose intolerant the

60:32

moment they become adults

60:33

I guess that's a question of why and

60:35

then and then how why probably because

60:38

if University aged Johnny is clamped

60:41

onto your boob and there's limited space

60:42

there's no room for baby Johnny and so

60:44

you need to encourage a rapidly growing

60:46

mammal get away go eat solid food so

60:48

that other babies can actually get on I

60:50

think that probably is the real reason

60:51

to encourage animals to do the more

60:54

difficult thing of finding solid food so

60:56

you make yourself lactose intolerant how

60:58

Okay so uh lactase is the enzyme that

61:02

breaks down lactose and this happens in

61:04

your small intestine and it turns it's

61:06

turned on when we're babies but then as

61:09

we become older something else comes and

61:12

shuts off lactase like in me and so I

61:15

can't drink a lot of milk but then

61:17

around 7 500 years ago or so people

61:20

people have actually worked this out a

61:22

mutation occurred

61:24

near this Gene linear lactase which

61:27

prevents the shutting off of the gene

61:29

okay and so 85 percent of white northern

61:32

European Caucasians for example

61:35

can drink milk as adults every single

61:39

one of them has exactly that same

61:40

mutation that occurred 7 500 years ago

61:42

now there are other populations

61:44

throughout the world there's certain

61:45

pastoral populations in Africa and

61:47

certain populations

61:49

um particularly Those Who had who had

61:50

goats and sheep and stuff who then had

61:53

their own independent way of dealing

61:55

with drinking milk because it was a rich

61:57

source of food so if it was available

61:58

you were able to to to to drink it but

62:01

so that is the mutation whereas for the

62:04

vast majority of us Chinese people for

62:06

example you know we didn't end up

62:08

drinking milk as as adults

62:11

um and so we never had that we never had

62:13

that mutation and so most of us are

62:15

lactose intolerant as adults

62:18

and these things we can find out how

62:20

does one go about finding out about my

62:22

genetic predispositions to certain foods

62:25

and diets so you can okay not every

62:28

single food has a prediction for genetic

62:31

wise but if you take any of the direct

62:33

to Consumer genetic tests that are

62:34

available they will test all of the

62:36

known they'll they'll definitely test

62:38

lactose intolerance your ability to

62:40

handle alcohol okay I I know mine your

62:42

ability to to metabolize caffeine so

62:45

these are all individual genes so it's

62:47

predictable so some people can drink a

62:49

lot of coffee other people can't some

62:50

people can drink a lot of alcohol other

62:52

people can't I'm probably in the middle

62:53

for alcohol and I can't drink any milk

62:55

so all of those are predictable and you

62:57

can get from any of the genetic tests

62:59

that are there the problem I guess with

63:01

these genetic tests is they make

63:04

predictions beyond the stuff that are

63:06

predictable they say that oh we can

63:09

predict that you'll respond to a

63:10

Mediterranean diet for example I'm

63:12

Mediterranean diet is a whole diet it's

63:14

it's got like whatever 200 Foods how is

63:16

it going to predict whether or not you

63:17

respond to it and so I think some of the

63:19

genetic tests overstep their Mark in

63:22

trying to predict what they can predict

63:23

but some things are predictable milk

63:25

caffeine alcohol have you done any

63:27

genetic tests I have for for a um uh

63:31

23andMe DNA fit uh Circle I I've just

63:34

done them for some for papers uh

63:37

newspapers and writing reviews for

63:39

others just for personal

63:41

um interest just just to find out what

63:43

it is what was your favorite

63:45

because I know people are going to be

63:46

listening and they're going to be going

63:47

you know I want to take action so

63:49

where's step one and I have to be honest

63:51

my girlfriend texted me yesterday asking

63:52

me this exact question so the minute

63:55

this conversation is done I'm gonna say

63:56

I've just spoken to this genius from

63:57

Cambridge and now for you babe and I've

64:00

got you the answer

64:01

she texted me yesterday asking me for a

64:03

good uh DNA genetic test that will help

64:06

her understand diet

64:08

help her understand her diet yeah like

64:11

her like tolerance to certain foods and

64:12

predispositions okay so there are many

64:15

different tests out there testing

64:16

different things

64:18

so um

64:20

there is an advantage to going with size

64:22

like 23andMe obviously I'm not paid by

64:25

them it has an advantage to size because

64:27

they have tens hundreds of millions even

64:29

people's data and so as with most things

64:31

the more data you have and people

64:34

constantly interact with the app the

64:35

more you can

64:37

improve your product the more you can

64:38

then improve your predictions but

64:41

23andMe only tests a limited number of

64:44

the genes in your in in yourself okay so

64:47

in other words we have three billion

64:49

base pairs in our DNA each each

64:51

individual Mark a 23 and me I'm going to

64:54

get this wrong I'll probably test about

64:56

2 million or so okay of the three

64:57

billion whereas if you go to some other

65:00

companies now that now in effect

65:02

sequence your whole genome or at least

65:05

all your genes

65:06

so you get a lot more information

65:09

then they get more information the

65:12

problem there however is a is more

65:13

expensive but B fewer people have done

65:16

it and so they haven't yet had the time

65:18

to begin to tweak their algorithms and

65:21

their predictions to get a more

65:23

optimized optimized prediction so that's

65:25

the problem right okay whereas 23 me is

65:27

cheap so that's probably a good place to

65:30

start to ask certain questions look I am

65:33

happy to to like literally literally

65:35

happy to give you a better prediction

65:38

than 23me's algorithms because I can

65:41

um for for that for for example but they

65:43

probably give a pretty uh helpful look

65:45

about lactose alcohol you know and

65:48

whether or not you may or may not be uh

65:52

um gluten intolerant they give some

65:54

pretty good uh predictions there

65:57

okay I'm gonna do that whatever yeah I

66:01

really need to do I really I've been

66:02

I've been thinking about it for a long

66:03

time so I'm gonna pull the trigger um

66:05

it's quite remarkable that I haven't yet

66:07

um you did a documentary called clean

66:09

eating

66:10

which is um predominantly about

66:12

plant-based eating it wasn't predominant

66:15

I did look at plant-based I also looked

66:17

at The Alkali diet and I also looked at

66:20

gluten-free so let's talk about those

66:21

last two then so

66:23

um plant-based diet I I heard that there

66:25

was a lot of adverse reaction

66:28

from some people in some communities

66:30

regarding the plant-based component of

66:34

that documentary is that true or false

66:36

that is true that is true and and the

66:38

reason there was a problem was look I I

66:40

hope you think

66:41

speaking to me that I'm a reasonable

66:43

person I speak with some Nuance I don't

66:46

think so what we did was was a plot

66:49

based has taken on a different meaning

66:50

today okay based on the supermarket so

66:53

what have you but when I did the program

66:55

plant-based meant a far more restrictive

66:58

version of veganism plant-based meant

67:00

that you ate you ate minimally processed

67:02

foods hardly any sugar and you ate at

67:04

Whole Foods only it's fine it's a

67:06

perfectly healthy it's a perfectly

67:07

healthy diet as long as you take the

67:08

right supplements the problem is

67:10

the plant-based people become vegan or

67:13

plant-based for many different reasons

67:15

ethical reasons environmental reasons

67:17

and health okay all three or or a mix of

67:20

the three the the one issue I took with

67:23

the plant-based community in that

67:25

program is that they believed that there

67:27

was no safe dose of animal protein okay

67:31

which meant that even eating a bit of

67:33

egg white the moment you started eating

67:35

a bit of egg whites it begins to kill

67:37

you slowly in your you know because I

67:40

says that's the most ridiculous thing

67:41

I've ever heard in my life and it

67:42

doesn't support the science doesn't

67:44

support it we eat too much meat the

67:46

science does support that okay but

67:49

eggs okay

67:51

um um you know people vegetarian you're

67:53

calling vegetarians they're killing

67:54

themselves because they're eating eggs

67:55

or something that was what I took them

67:58

up on and they thought that because I

68:01

was challenging I said there is a safe

68:02

dose of animal protein we do need to eat

68:05

less meat that's but that's they went

68:07

after me they went after me oh my god

68:09

um it was it was amazing in fact the

68:12

program has probably gone around the

68:14

world probably four or five times and

68:16

the reason why I know is because every

68:18

time it pops up in a new you know BBC

68:19

doesn't tell me every time it pops up in

68:21

a new country I wake up to my inbox on

68:24

my social media and suddenly I got a

68:25

rush of hate ah the Canadian vegans have

68:28

seen it again oh look it's in Australia

68:30

oh the Swedish vegans hello you know and

68:33

and and so and it's just this really odd

68:37

Evangelical Evangelical I want to point

68:39

out I know this you know please it's the

68:42

people that believe there is no safe

68:43

dose of animal-based protein clearly

68:45

there is a safe dose

68:48

um there are different reasons for doing

68:49

things but don't say silly things that's

68:51

what that's what got me into trouble

68:52

with with the Evangelical vegans because

68:54

I've watched some sort of plant-based

68:56

vegan documentaries on Netflix and I

68:58

come away from them thinking Christ I

68:59

should never eat any meat ever again for

69:01

a variety of reasons actually the

69:03

reasons that I think they tend to lead

69:04

with are are more about the impact upon

69:08

your health and your diet I think that

69:10

that's a much more

69:12

compelling

69:14

um self for most people especially for

69:16

people in in parts of the world whether

69:18

they have

69:19

another set of problems they're dealing

69:21

with first which is trying to feed

69:22

themselves period

69:24

um but as it relates to health and

69:27

veganism plant-based diets what are some

69:31

of the stereotypes there that that

69:33

you've highlighted one that there is a

69:36

quantity of meat products that is

69:37

healthy what are the general stereotypes

69:40

there that are they need a dressing so a

69:43

couple of things that that is it healthy

69:45

to be on a plant-based diet let's just

69:47

deal with that first okay and I think as

69:49

long as you do it carefully and think

69:51

about it and take the right supplements

69:54

it is you have to supplement when you're

69:57

on a plant-based diet okay you have to

69:59

supplement certain things vitamin B12

70:01

iodine iodine pardon me

70:04

um

70:04

you got to watch your iron you've got to

70:06

watch your calcium but you can do it

70:08

safely okay but I just

70:13

the biggest myth that I want to bust is

70:16

that it's a diet for everybody it is not

70:19

veganism plant-based in particular is a

70:21

diet for the privileged people who can

70:24

choose to do so I can choose to do it

70:26

you can choose to do it if you live in a

70:29

developing country okay or no no don't

70:32

ever stop that not even living in a

70:33

developing country if you are Mrs Smith

70:35

working two minimum wage jobs okay in

70:38

this country trying to feed your kids

70:39

are you really going to be concerned

70:42

with your pulses and making sure the

70:44

supplements are right to actually feed

70:46

your kids so they can have a vegan diet

70:48

no you want to feed your kids all right

70:50

and so what annoys me about about

70:54

Evangelical uh plant-based and vegan is

70:57

not that people do it people should do

70:58

what they want to do but what they do is

71:00

they make other people feel bad by not

71:03

having their diet particularly when they

71:04

don't have the choice to do it that is

71:06

what that is what annoys me I've seen

71:09

some videos on social media we've

71:11

probably all seen them of certain

71:13

activist groups that want people to stop

71:15

eating animal products going into

71:16

supermarkets and taking the lid off of

71:19

the milk and just pouring it all over

71:20

the floor in protest if you were sat

71:22

with one of those people that goes into

71:24

supermarkets pours milk on the floor and

71:26

goes into the meat section and does

71:28

whatever

71:29

and they came to you and they said what

71:31

should we be doing instead in your

71:33

perspective

71:34

to

71:36

move people away from animal products

71:40

for moral or environmental reasons

71:41

whatever it might be what would be a

71:42

better strategy based on what you've you

71:44

believe in what you've studied we do not

71:46

need

71:47

ever we need to move the curve we do not

71:50

need everyone to be vegan we we don't we

71:53

okay there are going to be people who

71:55

are vegan and that's perfectly fine I

71:57

want to stress I am not energy vegan in

71:58

the slightest but what we need as a

72:00

world is for everyone to eat 10 to 20

72:03

Less meat today

72:05

that is achievable

72:07

don't eat meat at lunch don't eat meat

72:09

on Fridays whatever it is don't even

72:11

mean once a week we need to eat 10 to 20

72:13

percent less meat and Less meat products

72:15

why

72:16

for for two different reasons that the

72:20

environmental impact would be enormous

72:22

beyond anything the environmental impact

72:25

would be enormous and that would help

72:26

the the environment that's the first

72:28

thing it's interesting so cop 26 I think

72:31

was just finished and cop 27 is is

72:34

the the people were talking about

72:36

sustainable farming people were clearly

72:38

talking about fossil fuels all of these

72:40

need to talk about but no the term eat

72:43

less meat not eat no meat eat less meat

72:46

did not even make it to the discussion

72:49

it was not even mentioned in the in in

72:51

the final thing because people are too

72:53

afraid about the farm about the farm

72:55

Lobby okay

72:57

but that's because we're framing this in

73:00

a slightly the wrong way because people

73:01

think oh you want us to cut out meat

73:03

entirely you want us to destroy our

73:04

farming industry no we need to just eat

73:07

a little bit less meat all of us

73:09

immediately for the environment and

73:10

actually that will also turn to to our

73:13

health as well so that I think is the

73:16

framing we need to go for rather than

73:18

saying that veganism and everyone needs

73:20

to be everyone needs to be um vegan

73:23

because that puts people off

73:25

and that's whereas if you don't have

73:28

meat one day a week two days a week even

73:30

if you want to do it four days a week

73:32

whatever you want to do most people can

73:34

do that quite easily

73:36

you know on this discussion on this

73:38

debate

73:40

some people are very morally in touch

73:44

and you know they care a lot about the

73:46

environment and the world and I applaud

73:48

those people but then other people will

73:50

think and I've heard certain

73:51

commentators who I shant name say you're

73:53

not taking my stake from me I don't care

73:56

and and that's a real so so there has to

73:58

be something that feels like more

73:59

systemic that we do in society to really

74:02

affect change because people are I think

74:04

quite naturally often not always but

74:06

often quite selfish and they don't

74:08

really think about the big picture they

74:09

think well I'm not going to be alive to

74:10

observe the effects of those things

74:12

anyway so is there anything that we

74:14

could do at systemic level whether it's

74:15

supermarkets whether it's I don't know I

74:17

don't know tax whatever it is to try and

74:19

reduce the amount of that of meat that

74:21

people are eating

74:23

or is that the right approach I okay

74:25

okay I mean the the term taxation always

74:28

scares people it does yeah okay and I

74:31

guess actually punitive such as taxation

74:33

is always

74:34

always does two things it always

74:36

disproportionately affects poor people

74:38

and it always makes lawyers Rich two

74:39

things happen I think a better way of

74:42

doing it is to try and get people to

74:44

choose the healthier choice whatever the

74:46

health of your choice might be make that

74:47

the easier and cheaper choice now this

74:49

could be

74:51

um subsidizing it this could be putting

74:53

it in different parts of the supermarket

74:55

this could be

74:57

um

74:57

stopping subsidizing um Dairy you know

75:01

the the meat industry there are any

75:03

number of different things you can put

75:04

in place so that you sort of you can't

75:07

make something more expensive without

75:08

making something cheaper that's the

75:10

bottom line

75:10

otherwise it will is not Equitable so I

75:13

think that's what we need to do but

75:14

subtly once again I'm going to sound is

75:17

on the one hand I'm saying that there's

75:19

a safe dose of meat on the other hand

75:20

I'm saying eat less meat but that is

75:22

that is the answer it's a nuanced answer

75:24

where we eat too much meat and and for

75:27

us the privilege we at least have a

75:29

responsibility to try and eat to try and

75:31

eat less meat because we have the choice

75:33

we have to wear with all in in order to

75:34

do it and so I think that is what we

75:36

need to do we need to take a more

75:37

nuanced view about it less Evangelical

75:40

understand that people's socio-economic

75:42

place on the on on said ladder is

75:45

important about the choices which they

75:47

have we need to make healthier food

75:49

whatever you wanted healthy for the

75:51

planet healthy for the environment okay

75:53

we need to make it the cheaper easier

75:55

and more convenient Choice that's what

75:56

we need to do that is the answer for a

75:58

lot of environmental issues isn't it you

76:00

know when you think about developing

76:01

countries if we make the alternative

76:04

that is the environmentally friendly

76:06

alternative cheaper faster easier more

76:08

accessible people will naturally choose

76:09

it it's a cool friend Innovation I guess

76:11

versus

76:15

you let Market forces leave because the

76:17

moment you try and make people do

76:19

something a most of us are selfish we

76:23

don't like being told what to do whereas

76:25

if we sort of think we made the choice

76:27

because it's the easiest choice then

76:29

there's no choice because then because

76:30

then you just do it and I think that is

76:32

the way that we have to do it

76:33

interesting

76:35

let's talk about something else which I

76:37

feel like I was lied to about oh God

76:39

which is juice orange juice oh yes Apple

76:43

Juice I was told when I was young that

76:46

orange juice and apple juice and all

76:48

these juices was healthy so I spent 25

76:51

years waking up in the morning and

76:53

drinking as much of this fruit juice as

76:55

I possibly could

76:57

now when I read your book when I started

77:00

um speaking to other people when I spoke

77:01

to Tim Spector I found some alarming

77:04

things one of the really alarming things

77:05

you said was the comparison with

77:06

Coca-Cola

77:08

tell me about that so so orange juice or

77:10

apple juice but both of those juices in

77:12

particular have as much sugar

77:14

concentration exactly the same sugar

77:16

concentration as Coca-Cola is it not

77:18

different sugar it's not different sugar

77:20

so so it is different in terms of in the

77:22

juice because of its sauce so it

77:24

probably has more vitamin C it probably

77:25

has a couple more minerals okay yes

77:27

those are true but the actual

77:30

bottom line is it's still mostly sugar I

77:33

say mostly sugar I think 12 a

77:35

concentration sugar now and orange juice

77:37

same for Coca-Cola the sugar is exactly

77:40

the same sugar but yet when you do sugar

77:43

taxes you you tax the coca-colas of the

77:45

world iron Brews of the world but you

77:47

don't tax orange juice okay now I make a

77:51

huge distinction between orange juice

77:53

apple juice and eating the damn orange

77:55

because when you eat the orange

77:58

it's exactly the same source of food

77:59

right so you drink a a glass of juice

78:01

what happens is there is nothing to

78:03

digest because because of sugar so your

78:05

body just absorbs it whereas if you eat

78:07

exactly the source of food orange like

78:10

whole orange like a normal orange first

78:12

of all you chew yeah and so because

78:13

you're chewing your body then senses oh

78:15

chewing happening okay guys guys get an

78:18

order we're gonna about to receive

78:19

energy okay that's the first thing

78:20

second because your body then has to

78:23

work through the fiber this is the

78:25

caloric availability thing to then

78:27

extract the sugar

78:28

instead of having all of the sugar

78:31

absorbed into your blood all at once

78:33

because there's nothing there's nothing

78:34

to do it takes a little while down the

78:35

gut for the for the sugar to get in so

78:37

exactly the same amount of sugar and

78:39

exactly the same amount of calories is

78:41

delivered into your blood but over a

78:43

longer period of time and thirdly

78:45

because you're eating fiber it travels

78:47

further down the gut it makes you feel

78:48

Fuller you eat less of something else

78:50

during the day so that's the problem

78:52

with orange juice eat I I really think

78:55

that orange juice in very many ways is

78:58

worse than Coca-Cola not because of his

79:00

because when you are drinking a

79:02

Coca-Cola you know you're drinking a

79:04

Coca-Cola I'm drinking a Coca-Cola when

79:06

you're drinking orange juice a lot of

79:08

people think that this is the health

79:10

version this is I'm being healthy this

79:13

is what I should be drinking

79:14

whereas is that where is it is but it's

79:17

true you should eat an orange or drink

79:19

water or something else or drink it as a

79:22

treat drink it like you would drink

79:23

Coca-Cola the other thing you said was

79:25

about the alkaline diet now I read on

79:30

Instagram that alkaline water is better

79:32

for you so there was a period of my life

79:34

about a month where I just started

79:36

guzzling I said it's my system I said

79:37

please it's not alkaline water I don't

79:39

think we should put it in the fridge I

79:40

just want alkaline water and then I saw

79:44

some other thing which said alkaline

79:45

water is a total scam

79:47

you nodded your head when I said the

79:49

scam thing is alkaline water a scam yes

79:53

no

79:54

it's gam capital s c a m look what is

79:57

alcohol what where did this Alkali thing

79:58

come from so our blood pH

80:01

is 7.4 and above seven is alkali below

80:06

seven is acidic okay so it is slightly

80:08

Alkali and so some guy and I I

80:11

interviewed him actually

80:13

um just before he went to jail we'll

80:14

discuss why in a second

80:16

um just before he went to jail the guy

80:18

who founded the Alkali diet okay a guy

80:20

called Robert Young Dr Robert Young

80:22

um who said that well if we have

80:24

um an Alkali blood in order to keep

80:27

ourselves healthy yes and our Alkali

80:29

blood is healthy blood we need to eat

80:31

Alkali Foods this is his his thesis the

80:34

problem is it completely ignores the

80:37

presence of the stomach now the stomach

80:39

as far as a compartment in our body goes

80:41

is the most acidic compartment in our

80:43

body pH 1.5 it's like battery acid but

80:46

then all the food we eat goes into our

80:48

stomach gets acidified and then as it

80:50

goes into our small intestine it gets

80:52

neutralized back to seven again this is

80:54

just biology so nothing we eat

80:56

everything we eat is acidified and

80:58

neutralized nothing we eat will change

81:00

the pH of our blood that's the first

81:01

that's the first thing so if you drink

81:03

the water it becomes pH 1.5 and ph7 by

81:06

the time the water is absorbed into our

81:07

body it's pH seven whatever its starting

81:09

pH was the second problem however is the

81:12

taxonomy is what they consider Alkali

81:14

and acidic so I'll just give one example

81:17

they consider citrus fruits lemons to be

81:22

Alkali except lemons contain citric acid

81:26

it is a citrus fruit and vitamin C which

81:29

is otherwise called ascorbic acid it is

81:31

an acidic fruit

81:33

so how can it be considered itself

81:34

Alkali I don't even understand that

81:36

there's a famous I don't want to get

81:37

myself into trouble but there's a

81:39

there's a there's a famous image

81:40

of a certain actress who runs a certain

81:42

website beginning with G and ending with

81:45

p you know where where is

81:49

I'm not good at quizzes or crosswords or

81:52

anything but so so where she's drinking

81:54

her high pH water and squeezing in lemon

81:57

juice now what happens when you put acid

82:00

into a high pH water The Alkali diet

82:02

makes absolutely no sense whatsoever the

82:04

question is why do people stick to it

82:06

okay and people stick to it because the

82:08

Alkali movement considers meat and dairy

82:11

products acidic leave aside the fact

82:14

that meat are full of blood and his

82:16

alkaline would leave that alone but

82:17

because they consider meat and dairy

82:20

products acidic in effect you don't eat

82:22

meat and dairy it is a vegan diet it's a

82:24

plant-based diet so Alkali food is a

82:28

restrictive plant-based diet which is

82:30

why people stick to it which is why

82:31

people lose weight

82:34

a point of losing weight

82:35

um there's this thing called The Weight

82:37

Watchers which you talk about in one of

82:38

the chapters of your book chapter 11.

82:39

yep Weight Watchers are these things

82:41

good these like groups of people that

82:43

are like losing weight together

82:45

so I think that really does depend on

82:48

who you are and um and what you like a

82:51

lot of people swear by it because they

82:53

enjoy the community Spirit the fact that

82:56

there is a group motivation

82:58

um to try and help you do stuff and

82:59

we've seen this right we've seen it

83:01

where it's easier to go jogging or

83:03

exercising when you've already made the

83:04

appointment at 8am on a Sunday you are

83:07

less likely to call your maintenance I'm

83:09

back bunking out I I'll go because I

83:12

really it's a social path it's a social

83:13

Pact

83:14

that being said there are public

83:16

weigh-ins and there are people who are a

83:18

bit shy there are people who are

83:19

mortified that they actually have to

83:21

weigh themselves in front of other

83:22

people and I get so stressed out I'm

83:24

stressed out about this so it suits

83:26

people of a certain character who like

83:28

that and I think they should keep to

83:30

that because it's a strategy it works

83:31

the people who really hate it with the

83:33

passion of a thousand Sons I think they

83:35

should stay away I think they should

83:36

find find another because then it could

83:38

tilt some people into Eating Disorders

83:40

if you take the wrong if you force

83:42

everyone to do it okay it could it could

83:45

go the wrong way so find the people who

83:47

it works for and by all means they need

83:49

to to to to stick to that whereas other

83:51

people need to find another way is it

83:53

true that I think a lot of people

83:54

believe now that there's a sort of

83:57

certain

83:59

a default weight size based on our

84:02

genetics that we have that will keep

84:06

returning to we kind of touched on a

84:07

little bit earlier on

84:09

um

84:10

regardless of what diet we do so I'm

84:12

thinking of some you know families often

84:14

look quite similar yes in terms of body

84:16

shape and size Etc

84:19

um I'm wondering how much like control

84:21

they have against fighting against those

84:23

genes to to get a you know six-pack abs

84:25

not saying that's a sustainable healthy

84:27

place to get to but

84:29

is it significantly harder for certain

84:31

people if their family is maybe a little

84:33

bit more larger to get to to fight

84:36

against that and get to a different

84:37

state and then stay in that state yes

84:39

undoubtedly so so there is certainly

84:41

what we call it used to be called a set

84:43

point hypothesis meaning that each of us

84:45

has a weight we actually protect it's

84:48

probably more Nuance than that set range

84:50

there's a range that you can actually

84:51

range that we find easy to keep their

84:53

weight so in other words I'm not

84:55

thinking about my body weight at the

84:56

moment and this is the weight that I am

84:58

but I wish I was half a stone or a stone

85:00

lighter but if I lost that half a stone

85:02

I would then have to think about food

85:04

all the time to keep that half a stone

85:05

off whereas I get half a stone more and

85:07

I don't raise my weight anymore so

85:09

that's the idea where there's a there is

85:10

a a weight range is easy to protect and

85:14

each of us is different there are some

85:15

people who are skinny there's some

85:18

people who just find it more difficult

85:20

to say no to food than others that's

85:21

pretty much it so some people's

85:23

thermostat and food is set a little

85:25

higher than others and you defend that

85:27

thermostat 25 degrees versus 20 degrees

85:29

and there's really next to nothing you

85:32

can do you can shift from 25 to 24 and a

85:34

half and maybe after Christmas you're 25

85:37

and 0.5 okay and so you shift around

85:39

there but the likelihood of you getting

85:41

down to 20 and staying there you can get

85:43

down to 20 okay if you do some stupid

85:45

diet but the moment you're paying you

85:47

ping back you ping right back up again

85:49

so we do defend

85:51

um there is very very little choice in

85:54

inverted commas in where we end up with

85:56

the body weight over a lifetime at any

85:59

given meal we have a choice you think

86:01

right pizza or no pizza pizza or no

86:03

pizza but over thousands of feeding

86:06

events

86:07

there's very little Choice what then you

86:09

reference age there do we get fatter

86:12

with age because generally I look at you

86:15

know I'd say younger people typically

86:17

have a slightly leaner physique and then

86:21

something seems to happen along the way

86:23

is that just a false observation I have

86:25

or is there some science that supports

86:27

the the gaining of weight as we age

86:29

there's science the a weight is

86:31

inexorably up okay even though we've

86:34

stopped growing when we're we're 18

86:36

years old actually there's some later

86:38

science I used to I used to if you would

86:40

ask me the question five years ago I

86:42

would have said that by the time we had

86:43

40 or 50 our metabolism starts to dip

86:46

that's part of the reason that's not

86:48

true as it turns out our metabolism

86:49

doesn't start to dip till we're 60. okay

86:51

but what happens as we get older are a

86:54

number of different things first of all

86:56

we tend to get richer we tend to get

86:57

more money

86:58

we tend to sit on our ass more okay just

87:01

in terms of the type of jobs we do okay

87:03

and because of both of those things we

87:05

tend to exercise less because we're

87:08

busier and so we lose muscle mass those

87:10

are all three things metabolically the

87:12

most active part of your body are the

87:14

muscles so when you're younger and

87:16

you're doing things and you have more

87:17

time to go to the gym first of all your

87:19

metabolic rate is linked to the amount

87:21

of muscle you have and so as you get

87:23

older you're set on your RS you eat a

87:25

bit more we don't eat less we eat more

87:26

and we can buy richer food because we

87:27

got more money and you begin to lose

87:29

muscle mass so all of those things put

87:31

together means that you inexorably

87:34

become larger then what happens at 60

87:36

years old your metabolism then starts to

87:38

drop as well and then you get even

87:40

larger middle age spread Etc

87:43

so on that point about the more muscles

87:45

you have the higher your metabolism that

87:47

means if I'm if I've got big muscles

87:49

then I'm burning my food faster yes

87:51

fantastic news I'm going to work out

87:52

later lift some weights um because I was

87:55

really started by that I after I read it

87:57

in your book about us gaining more and

87:59

more weight as we age I Googled it and

88:02

the healthcare research and quality

88:04

agency said that we naturally tend to

88:08

gain weight as we age to the tune of one

88:10

to two pounds per year according to

88:12

their review and that's from the agency

88:15

for healthcare research and quality

88:18

which I found quite startling but

88:20

completely accurate so the numbers so

88:22

what what the numbers that we have is

88:24

yeah I think that's right actually so

88:25

between 20 and 50 years old those 30

88:28

years intervening the average person

88:30

average will gain about 15 kilos in

88:33

weight which is 32 points yes two pounds

88:35

a year one to two pounds a year 15 kilos

88:38

in weight is gained over 30 years on

88:39

average some gain very little others

88:41

gain a hell of a lot more we look at

88:42

ourselves in a mirror I look at myself

88:44

in the mirror um but that's true I don't

88:46

want to be that guy

88:47

mate I don't know how much choice you

88:49

have what can I do to to to try and stay

88:53

because for me it's not really about the

88:55

weight thing or how you look it's more

88:56

about like I

88:58

I am I don't know how to say this but

89:01

there was this big set of stairs the

89:03

other day

89:04

really really long set of stairs leading

89:05

down to this Lake I was in Indonesia a

89:07

couple of months ago

89:09

um and I I remember thinking about those

89:11

stairs and thinking God if I wasn't you

89:14

know

89:15

athletic and strong and didn't have good

89:18

knees and things like that there's no

89:20

way I'd be able to get down this long

89:21

winding hand carved set of Indonesian

89:25

stairs so that I could go on this boat

89:26

trip that I was going to go on and I

89:28

just thought about how it was a weird

89:31

thing I know this is kind of a strange

89:32

story to tell but it crossed my mind I

89:34

got to the bottom of the stairs and I

89:35

turned to the person I was with and was

89:36

literally like you know that's why I've

89:37

got to stay in shape for as long as I

89:39

can because I want to do these boat

89:40

trips and I want to go on this little

89:41

rafting thing but I won't even be able

89:43

to access it unless I can go down up and

89:44

down those stairs like 200 meters of

89:47

stairs down this Cliff

89:48

um so that's what I care about I care

89:50

about being active and strong and fit

89:52

for as long as I possibly can and I from

89:54

what you've said about gravity and

89:56

weight

89:57

um being overweight is going to inhibit

90:00

my chances of being able to do those

90:01

stairs so so that I think there are two

90:03

elements there first of all there is

90:05

doing the things that we want to do okay

90:07

like that because you're exactly right

90:10

these are the things which I can still

90:12

do that I can still walk up a mountain

90:13

or down a mountain because I'm still fit

90:15

enough to do that and I want to stay as

90:17

fit as long as I can to do that and

90:19

weight will inhibit that undoubtedly

90:21

but then there's a second element to

90:23

actually consider now there's Healthy

90:24

Look none of us are going to live longer

90:26

we hopefully

90:28

and anyway if we left lived longer but

90:31

was unhealthy would you want to live

90:32

longer so you want to live longer but

90:34

healthier for longer okay and

90:36

undoubtedly the thing that is closest

90:39

related to health when you age is not

90:42

your total weight there's a role to play

90:44

there the amount of muscle you have it

90:47

is your muscle mass as you age

90:49

independent of how much fat you have

90:51

okay that will determine how healthy you

90:55

are as you age so as so now the moment

90:57

now I'm talking about going into the 60s

90:59

and the 70s rather than when one is able

91:02

to go down to 200 meter set of steps

91:03

okay so now as you get older the most

91:07

crucial bit of information is to

91:10

maintain resistance training not lifting

91:12

and that's not what I'm talking about

91:13

sitting on a wall getting up and down a

91:15

chair because of that the amount of

91:17

muscle mass you have really really

91:20

really marks the level of Health that

91:22

you're going to get and then the science

91:24

is startling it is so so so related

91:26

independent of independence of weight

91:28

you know from from there so muscle mass

91:30

is the most important for healthy aging

91:32

the moment you get 60 70 plus

91:35

interesting okay so I'll keep I'll keep

91:38

doing resistance training correct always

91:40

keep resistance training and lifting

91:42

weights as long as I can lifting weights

91:43

as long as you can at some point you

91:45

won't be able to lift weights just

91:46

because don't write me off don't write

91:49

me off John the hubris of Youth yeah

91:53

you just assume you'll always be able to

91:55

do what you can do now I I yeah it's

91:57

something I think a lot about and I

91:59

think a lot of people will watch this

92:00

podcast because

92:02

probably especially this time of year

92:04

we're in January they'll probably be

92:06

trying to find ways that they can cut

92:08

fat they want to be a bit skinnier you

92:10

said you think you said half a stone you

92:11

want to lose I'm in the same place I

92:13

think most people want to lose a half a

92:15

stone or something

92:16

what is the way that you would suggest

92:19

to do that the simple way you know not

92:20

the like like in complicated go buy this

92:23

guy's course and do three million

92:25

sit-ups whatever the simple advice you

92:27

would give someone that's hoping to

92:29

create sort of sustainable weight loss

92:32

okay so this this something's like the

92:35

last page of of the why calories don't

92:37

count book but it is a set of numbers

92:41

and I know I said not to count calories

92:43

but it's a set of numbers that is that

92:45

you can apply to whatever diet you like

92:47

so the first is the amount of protein

92:49

you eat and you need to try and focus on

92:52

trying to keep to about 16 of the energy

92:54

in your day okay from protein 16 and

92:57

there's a sweet spot so if you eat too

92:59

much

93:00

and you're not lifting you're stressing

93:03

your kidneys because your kidneys have

93:04

to get rid of the nitrogen from the

93:05

protein okay so 16 is a sweet spot and

93:09

it doesn't mean steaks only it can mean

93:11

beans tofu any kind of protein from from

93:13

anywhere 16 second is fiber we need to

93:17

eat as much fiber as physically possible

93:19

okay 30 grams we want to aim for

93:22

although we're looking at the moment on

93:23

average in this country we're probably

93:25

only eating 15 grams we need to double

93:27

the amount of fiber we actually eat

93:29

third we need to limit the amount of

93:32

added sugars into our diet added sugars

93:35

meaning sugar is not tied up in fiber

93:37

powdered stuff uh uh um maple syrup

93:42

Algarve nectar all those are added

93:44

sugars you put in keep it to five

93:45

percent or less of the of the energy

93:47

content in your day and those are the

93:49

three numbers that that I want you to

93:51

think about so 16 of protein 30 grams of

93:54

fiber five percent or less of added

93:56

sugars apply that to whatever you want

93:59

what Keto

94:01

um whatever you want to do apply that

94:03

and I think that will be a sustainable

94:05

healthy way to eat

94:08

now there's been a lot said about

94:10

exercise as a weight loss strategy a lot

94:14

of people think you know what I will

94:15

just run every day and I'll lose weight

94:17

in your books you said

94:19

um the problem with using exercises

94:21

weight loss strategy is that doing

94:23

exercise makes you feel hungry you can't

94:25

outrun a bad diet is exercise a good

94:29

strategy for weight loss it is a good

94:31

strategy for weight loss if you're an

94:33

Olympic athlete or a Tour de France

94:35

writer what if you are a muggle like me

94:38

a muggle like you a muggle like me then

94:41

exercise okay exercise you can never

94:43

replace the goodness and wonderfulness

94:46

and health benefits of exercise is

94:49

exercise exercise a good weight loss

94:50

strategy for a muggle like Steve no

94:54

it's a good weight maintenance tool

94:56

though so in other words once you've

94:57

lost the weight which means you need to

94:59

be less somehow exercise helps you keep

95:01

the weight off so once you've actually

95:04

lost the weight that you that you're

95:06

aiming for whatever whatever that might

95:07

be then do the exercise and that will

95:10

help keep the weight off but it's not

95:12

going to help me get the weight off in

95:13

the first place no

95:16

that seems to sit in contradiction to

95:18

what my old personal trainer only

95:21

because we don't do it enough

95:22

so now if you had okay let's put it this

95:24

way let's put it this way the way that

95:26

it would work is if you had a personal

95:28

trainer and a chef then what would

95:30

happen is your personal trainer will

95:31

make you work hard and your Chef will

95:33

make your meal okay therefore what

95:36

happens is it is controlled on both

95:38

sides that is not typically what happens

95:40

in in the real world I go on my run my

95:43

cycle what have you I come back I'm

95:44

ravenously hungry I open the fridge and

95:46

i stuff my mouth full of carbs that is

95:47

that that is my story right and so it is

95:51

very difficult to control your diet

95:52

after you've done long Hard Exercise

95:54

bouts because you get ravenously hungry

95:57

so professional sports teams a day

96:00

exercise ridiculous they train three

96:02

times a day so that's that's that but

96:04

they still have chefs and dietitians and

96:06

they eat what they what what they the

96:07

you know the canteen puts out for them

96:09

which is healthy food so someone is

96:11

looking after their diet for them but

96:13

they are burning so much they don't have

96:15

to worry too much about how much they

96:16

eat whereas we we do it's I know it's

96:19

counter-intuitive in some sense but it's

96:21

purely because we don't exercise enough

96:24

and is that also because ultimately

96:26

because the brain is controlling our

96:27

feeding Behavior so the brain is knows

96:30

that we've just been for a run so it's

96:32

it's adding

96:33

to our appetite yes uh a serp a surplus

96:38

to make us return to that that weight

96:40

it's trying to protect there's that and

96:43

there's also our own internal psychology

96:45

on it because now you feel a bit smug

96:47

you say oh I went for my run on Sunday

96:49

morning you know and then so I can eat

96:52

what I want and there's that element too

96:53

so suddenly when you normally would say

96:55

oh I better not eat so much today I

96:56

haven't there are some internal controls

96:58

that we sometimes have those internal

97:00

controls are weakened once we've

97:01

actually had our exercise because we

97:03

feel that we have earned the food that's

97:05

in front of us

97:07

body positivity yes sir that is one of

97:10

the things you discuss in chapter nine

97:12

of why calories don't count now body

97:15

positivity

97:16

um I think there's a lot lots of pieces

97:19

to it one of the I guess the central

97:21

idea is that there's no such thing as an

97:23

unhealthy weight

97:25

I don't want to mischaracterize the

97:26

movement but um

97:28

what do you think about body positivity

97:30

so I understand where body positivity

97:34

comes from okay because obviously there

97:36

is a lot of waist stigma in society

97:38

um weight stigma for whatever reason is

97:40

one of the last rubicons left across if

97:42

if you or I made any disparaging

97:45

comments in public uh or anything about

97:48

someone's gender someone's

97:51

um sexual orientation skin color

97:53

whatever we get fired

97:55

but yet some people can make comments

97:57

about people's body size and have no and

98:00

it's perfectly acceptable how can that

98:01

be acceptable so I understand where body

98:04

positivity comes from but I think that

98:06

body positivity doesn't needs a little

98:09

bit more Nuance in their in their

98:11

argument so

98:16

why is it bad to be fat

98:18

we we talked about this carrying too

98:20

much fat because of the association with

98:22

disease but why okay and it's because of

98:25

the amount of fat we can store safely so

98:27

people misunderstand what happens when

98:29

you gain weight and lose weight they

98:31

think that you gain fat cells and lose

98:33

fat cells not true your fat cells are

98:35

like balloons they get bigger when you

98:38

gain weight and they get smaller when

98:39

you lose weight but they stay the same

98:40

number okay so what happens is the

98:44

safest place to store fat is in your fat

98:46

cells because they're your fat it's when

98:48

they're not in the fat that they go to

98:50

your muscle your liver they begin to

98:52

cause trouble okay and that's when you

98:53

become ill but the interesting thing is

98:55

everybody's fat cells can store

98:58

different amounts of fat before the fat

99:00

leaks out shall we say okay from that I

99:02

mentioned earlier East Asian South Asian

99:05

people we don't we can't store as much

99:07

fat safely than white people than than

99:10

Polynesians so the moment you get past

99:13

your safe fat carrying capacity you will

99:16

become ill now for some people that is

99:18

when that that skinny people with type

99:19

to diabetes and there are larger people

99:21

without uh that are that are healthy

99:23

that's because there's differing amounts

99:25

of safe fat carrying capacity but the

99:28

moment you go past your own personal

99:30

safe fat carrying capacity you will

99:32

become ill so in a big room you can have

99:35

health at many sizes

99:37

but there is no Health at every size

99:39

because you will become ill if you

99:41

become too big

99:42

interest that's the new ones

99:45

that doesn't mean I blame the people

99:46

suffering from obesity please but it

99:49

doesn't help anybody to not look at the

99:52

health issues that are associated with

99:55

carrying too much fat we have to discuss

99:56

it in a non-stigmatizing and non-blaming

99:59

language but we do need to be honest

100:01

about it yeah and I think we can both

100:03

agree that just generally

100:05

um targeting anyone which I've seen a

100:08

lot of a lot of like someone will be on

100:09

the front cover of a magazine and then

100:11

someone will like quote retweet it and

100:12

attack them and say that they're not

100:13

healthy and it's promoting

100:16

um bad you know bad body standards or

100:18

health standards whatever like whether

100:20

scientifically that's true or not you

100:22

are without a [ __ ] about an [ __ ] for

100:24

doing that you know what I mean you're

100:25

an artist and counterproductive

100:27

counterproductive it's making someone

100:28

feel like awful it's not you know it's

100:30

making people have the stigma as you've

100:32

said and it's if you think about it from

100:34

a psychology standpoint make shaming

100:36

people for how they feel is probably not

100:39

going to help

100:41

um them be proactive in making changes

100:43

if you think about how motivation works

100:45

with you know self-esteem and how we

100:47

feel and wanting to feel positive and

100:49

high self-esteem to make changes in our

100:51

life it's probably not an effective

100:52

strategy to attack people for the for

100:53

their body image regardless of whether

100:55

whether or not it's a [ __ ] move I

100:56

mean it does it exactly so I think we

100:58

can both agree on that yeah and um it's

101:01

super interesting I I I'm on my journey

101:03

with with eating in food so it's been a

101:05

huge pleasure to speak to you about this

101:07

because I feel now a lot closer to

101:10

understanding and having Clarity on on

101:12

what I should beating and what I

101:13

shouldn't what I really love about your

101:14

message is that it is centered in

101:16

um away from restriction and towards

101:19

positivity with food and to really like

101:21

loving food as opposed to being as

101:23

you've said with that word I think it's

101:24

as fix it no what was it that Bloody

101:26

orthorexia orthorexia it's not about

101:28

fearing foods which is an awful place to

101:30

get into I think we're getting closer

101:32

and closer to that kind of being fearful

101:33

of foods

101:34

it's just about I guess making

101:37

um a little bit more informed choices

101:40

um but also keeping the balance and the

101:42

and the chocolate and the other things

101:43

that are part of all of our Lives what

101:46

what's your mission

101:49

I'm assuming you have one when I asked

101:51

the question and I shouldn't do that do

101:52

you have a mission and if so what is it

101:54

oh so my my mission is to uh

101:58

destigmatize obesity

102:00

and try because look it is it is going

102:03

to roll like a tidal wave into every

102:05

single country across the world so my

102:07

mission is to destigmatize it because

102:11

destigmatizing taking away the weight

102:13

stigma means that we can have an adult

102:15

non-hysterical conversation with people

102:17

treating the patient the patient the

102:21

policy makers because at the moment

102:22

government thinks that a lot of it is

102:25

personal responsibility okay there is

102:27

obviously some personal responsibility

102:29

it's my health it's my children's health

102:31

that I understand but until we put money

102:34

in the right places fix the environment

102:36

make sure that the the treatment and

102:38

supports making healthier food cheaper

102:40

that's government responsibility and so

102:42

if we destigmatize obesity in the

102:45

population we can then have this

102:47

conversation with policy makers and get

102:49

them to put the resources in the right

102:51

place that is my mission because at the

102:53

moment the resources are being put in

102:55

the wrong place which is why we're not

102:56

solving obesity at the moment if I voted

102:58

FIFA prime minister

103:00

um and there was a couple of simple

103:01

things that you could do I think you

103:03

talked to it yep broadly there about

103:05

some of them what would be some of the

103:06

policies you would introduced to

103:09

Target the systemic issues that are

103:10

causing obesity in our population so day

103:13

one I would make healthier food cheaper

103:15

and this doesn't only mean carrots I

103:17

mean that they're going to be healthy

103:19

foods even within a chocolate bar

103:21

there's gonna be a way of actually

103:23

putting more fiber and protein in a

103:25

chocolate bar or frozen lasagna or

103:27

vegetables okay I think we need to make

103:30

healthier food cheaper all the way

103:32

across the board that's the first thing

103:33

we've got to do

103:34

um and that's the first thing I would do

103:36

the day after the day I'm prime minister

103:37

because then the default choice that you

103:40

make even if you're poor when you walk

103:42

into the supermarket is going to be

103:43

healthy which is not true at the moment

103:45

the moment that happens then I think we

103:47

are one step forward in trying to solve

103:50

the Obesity and diet related

103:52

epidemic that's actually around us today

103:54

but just to be clear you're not going to

103:55

cancel chocolate I'm not going to cancel

103:57

chocolate I'm going to try and make it

103:58

healthier you got my vote I love that

104:00

you're gonna make it healthier and

104:01

cheaper yeah you've got my vote

104:04

Giles thank you so much we have a

104:06

closing tradition on this podcast oh yes

104:08

the last guest asks a question for the

104:10

next guest

104:11

oh this is a long one

104:16

hmm okay

104:20

what is the worst thing that has

104:23

happened

104:24

in the last year it continues what is

104:29

the best thing that's happened

104:31

to you in the last year

104:36

from which have you learned the most

104:39

what is the worst thing that has

104:41

happened in the last year what is the

104:43

best thing that has happened to you in

104:45

the last year

104:46

from which have you learned the most

104:51

the worst thing that has happened to me

104:53

in the last year I think was we were

104:55

smack bang I forgot in the middle of

104:57

Omicron I think of of that

105:01

um and then my mum ended up with a

105:02

stroke so my mom she's fine now she's

105:04

fine now but my mum lives in California

105:06

which is which is where I'm from and

105:09

then life became very difficult I was

105:12

trying to find a way to get out there

105:13

without getting stuck out there anyway

105:15

that she she ended up being better but

105:17

there was a period of time there where I

105:19

was really seriously stressed about

105:21

about the whole about the whole scenario

105:23

that probably was the worst that

105:24

probably was the worst thing

105:26

um it turned out to be fine because she

105:29

was fine but it could easily have not

105:31

been have have not been fine

105:33

um so that that was probably the worst

105:35

of the worst thing over the past over

105:36

the past year that would probably be it

105:38

um because my own you know close family

105:40

is fine now what is the best thing that

105:42

has happened to me over the past year

105:46

that's an interesting question I'm not

105:48

sure I know what that I've had a good

105:51

year I've had a good year and I think I

105:53

can't deny that I'm privileged I've had

105:55

I've had a good year work has gone well

105:57

other things have gone well my family

105:59

are still with me my son is at Uni so I

106:02

think my family has been the best thing

106:04

as with most it's very boring answer but

106:07

as with many things um has been the best

106:09

thing that has happened to me over the

106:10

past year is that that's a cop-out

106:11

answer no yes again but there was a

106:13

third part to that answer with the

106:14

question which was from which have you

106:16

learned the most ah

106:20

from which I learned the most I think

106:22

that it's always I always think you

106:24

learn the most when things go downhill

106:27

um because that's the most that's

106:27

because then you start to reassess uh

106:30

priorities you start to think so

106:32

undoubtedly uh um yeah I should have got

106:35

that the first time around no no I think

106:36

you learn a lot more about yourself when

106:39

things go wrong rather than when things

106:40

go well you like it when things go well

106:42

it's when things when proverbial stuff

106:44

hits the fan that's when that's when you

106:46

learn more about yourself did it make

106:48

you reassess your priorities it did make

106:50

me reassess my priorities actually

106:51

because I began thinking okay uh um you

106:54

you know all these things which I was

106:55

planning on doing should I I'm Gonna

106:57

Cancel them now I'm Gonna Cancel them

106:58

now now now now

107:00

um you know and actually and actually uh

107:02

head back but but after a couple of days

107:07

my mom became a lot quicker she told me

107:09

look I have got people here supporting

107:10

me now I need you to come back a little

107:12

bit later so that I so I don't need

107:14

everyone my mom said to me I don't need

107:16

everyone here now that's not gonna I

107:18

need someone here in in a periodic uh

107:22

place place and time and so that's what

107:23

I did I went back later rather than

107:25

immediately although I did end up

107:28

canceling a bunch of things reassessing

107:29

the the importance of things to leave

107:31

almost almost immediately my mom stopped

107:33

me and is there a broader point I

107:35

reflect on when I spoke to Tim Spector

107:37

who's one of the quotes from the front

107:38

of your book here

107:40

um he talked about the passing of his

107:42

father and how that is part of the

107:44

inspiration that sent him off to to

107:46

think more about food the food he was

107:48

eating how he was treating himself

107:50

um and then I believe he had a stroke

107:52

himself which again was a bit of a sort

107:55

of tectonic

107:56

earthquake in one's life

107:59

when we see the health of those we love

108:01

and those that we are genetically

108:03

related to

108:05

um

108:06

have instances like that tragic

108:07

instances like Strokes or other health

108:09

issues or disease

108:11

is there something in the mind that goes

108:13

that kind of makes you look in the

108:15

mirror and go

108:16

sh you know like how am I living my life

108:19

what can I do to avoid

108:21

um having a similar diagnosis or ending

108:23

up in the same place or those kinds of

108:25

things

108:26

it is that is an interesting that is a

108:28

very interesting point because genetic

108:30

tests aside the most guarant not

108:34

guaranteed way the easiest way of

108:36

telling

108:37

the future of how where you're going to

108:39

end up is to look at your parents it's

108:41

very depressing I know but what do your

108:44

parents look like

108:45

what if they're still alive what

108:47

diseases do they have if they're not

108:48

what they did what did they die of this

108:50

is very morbid but but it's not because

108:52

you look at it it's it's a picture in

108:54

essence not 100 of your future you it's

108:57

certainly more accurate than any genetic

108:58

test at the moment and so exactly that

109:00

you look and it says oh God what did my

109:02

mom what what what did I have now I

109:04

gotta add Strokes into my risk you know

109:06

and then and then I look at my son what

109:07

is he going to do but do I need him to

109:09

exercise more it does reassess to say

109:11

that well is there anything I could do

109:13

yeah uh you know to avoid just just

109:16

ending up with a stroke so it does make

109:18

you think about things it also made me

109:20

think about the fact

109:21

that even though my mom was doing

109:23

something else not about that she was in

109:26

hospital yet there were people this

109:28

Insidious pseudoscience that we were

109:30

talking about was still able to seep

109:32

into a hospital into the person next to

109:34

her and people were talking about it

109:36

when they were seriously ill and not

109:38

even just talking about about

109:40

um about food they were talking about

109:42

trying to make themselves better but

109:44

through pseudoscience and that was the

109:45

other thing which jumped out of me I

109:46

said oh my God this can't you you know

109:49

it's there even in hospital even when

109:51

people are seriously ills people are

109:53

still talking maybe because they're

109:55

seriously ill they're talking about this

109:57

pseudoscientific approaches to to their

110:00

health and that's why your work is so

110:02

important Charles

110:03

um these books are fantastic they're

110:04

very accessible books they they're based

110:06

in evidence not necessarily opinion or

110:09

pseudoscience or anything like that

110:10

they're based in scientific evidence and

110:12

several decades of of work and research

110:15

um so I thank you for writing them

110:16

they've been a pleasure for me to read I

110:18

recommend both of them sometimes when I

110:20

have guests on this podcast I'll say get

110:22

you know tell my audience to get this

110:23

one or the other but I think they're

110:24

both absolutely fantastic books and

110:25

necessary and they're very very

110:27

interlinked you know those there's

110:28

things in um

110:31

why calories don't count Builds on a lot

110:33

of the stuff that I read in gene eating

110:35

as well so there's a they have a

110:36

relationship between them and it's been

110:38

fantastic to talk to you you're a very

110:39

um animated speaker which is what makes

110:42

a good podcast guest because people can

110:44

Interactive Summary

In this conversation, Dr. Giles Yeo, a leading expert on fat and obesity research, discusses the complexities of body weight, diet, and metabolism. He clarifies why calorie counting is often a flawed and overly simplistic tool for weight loss, emphasizing the importance of food quality and individual metabolic differences. Dr. Yeo explains the biological 'set point' that makes weight loss difficult, addresses common myths regarding juice, gluten, and alkaline diets, and advocates for sustainable eating principles centered on protein, fiber, and reduced added sugars rather than restrictive fads.
