well your noon everyone and welcome to
healthy living live I'm chef AJ and it
is my honor pleasure and privilege to
interview dr. Doug Lyall if you're not
familiar with dr. Lyle
you must get his extraordinary book that
he co-wrote called the pleasure trap you
might know him from his weekly podcast
which is called beat your genes fellow
GE and es if you're new to his podcast
at least listen to episode 161 he did an
episode a few weeks ago where he talked
about a pleasure trap and an ego trap
which was probably the best explanation
of both that I've ever heard you can
listen to his podcast live every
Wednesday evening at 8:30 p.m. Pacific
time and you can also find the replays
or even listen to it live on iTunes blog
talk radio Spotify probably stitcher by
now he's has over 160 wonderful episodes
and where else can you find him at the
mcdougal program where he's the
psychologist at the lipid program and at
the true more health center so thanks so
much for being here dr. Lyle oh it's a
pleasure AJ always it's been it's been
far too long since we've done one of
these live so if any of you are familiar
with the real truth about weight loss
summit that just took place over 11 days
absolutely free dr. Lyle was one of the
three poor experts and I've so many
wonderful comments about you I'm gonna
take a screen shot but I'm gonna just
read this one that came in yesterday
from Stephen Turner
he says Doug Lyle always manages to say
something that gives me kind of a gut
punch always worth listening to so
people really loved you and even though
the Sun was airing live the interviews
were pre-recorded so it wasn't like we
could just ask the speakers questions in
real time so we have now over 4,500
comments on the page which obviously I'm
not going to ask you you know 4,500
questions but there are even a few
topics on the summit that that many
people came full with with some
confusion and I thought maybe you could
shed some light on that so sure whatever
the first one so dr. Garth Davis who is
a well known plant-based of bariatric
surgeon in North Carolina did a
wonderful talk and one of the things he
was articulating is that people aren't
fat because they eat too much fruit I'm
not diabetic because they're eat too
much fruit and he's never had a patient
come to him for gastric bypass because
they ate too many apples and he started
talking about
the book Genesis which is something I
learned from Donna mcdougal and his
maximum weight loss book which I talked
about in my lecture and a lot of people
were confused like they realize that
people on the summit weren't all the
hyper conscientious in that cases that
find you and me these are people that
this may have been their first entry to
this topic or plant-based eating and so
the comments were looks like well I
can't believe that I can eat all the
fruit I want and not gain weight I can't
believe I can eat all the potatoes I
want and lose weight so people are
asking really is is it is DeNoble ippo
Genesis true is it true that human
beings really can't convert carbohydrate
to protein and that this way of eating
that we recommend is if dr. lawanda said
in the summit almost like a magical
buffet of food because people were
saying well can I eat all the dates I
gotta lose weight well dates are not a
whole natural food they're dry enough
Ohio caloric density so it's just
wondering if you could touch a little
bit on this de novo lipogenesis
and assure people that they really can't
eat a lot this way and not only not gain
weight lose weight well let's uh let's
try to get just the basics here let's
just touch on the basics the the most
the most important issue in in weight
management is going to be it's going to
be just overall calorie density that's
really the fundamental issue and it's
gonna turn out that we now have I've got
probably the first evidence hard core
evidence coming from the observation of
hunter-gatherers in East Africa that the
average calorie density of those people
is 700 calories a pound so that's you
know we've been aiming it we've had
previous data you know between 550 and
600 that we've been thinking about was
probably about right
looks like we under shot it a little
which is fine and it's undoubtedly true
that that that throughout the world in
world history there's been a range of
calorie densities that a given group of
people's has had the thing that probably
it's rarely been much above 700 and it's
probably never been as high as a
thousand in Maya might have been but it
would have been rare so it's going to be
that essentially the human digestive say
she ate
mechanisms are going to work really well
somewhere around 700 they'll work really
well at 600 they'll work well at 500
though 400 they may not work that well
at 300 300 calories a pound you may not
be able to eat enough to sustain your
your body weight mm-hmm optimally you
may be really on the really thin range
and we may find that at 300 calories a
pound a lot of women get so thin that
they that they lose their fertility
wouldn't surprise me at all the so we we
aim somewhere in our in our area around
500 600 but 700 now books is safer than
I thought so I want to just briefly step
through the foods that everybody's so
concerned about so people are concerned
about fruit because of its high sugar
but it's about 300 calories a pound
they're very worried about potatoes
potatoes are 375 covers a pound rice is
500 you start to see that that all of
all of the starches range from the
squash is an oatmeal down around 300 up
to the Rice's and grains around 500 in
other words they are all below the
fulcrum point of 700 covers a pound so
the we can see that that there's no
reason for us to be worried about
restricting these undoubtedly in the
history of America and the discussion
about potatoes and weight what confused
people is that people eat a lot of
potatoes they tend to eat a lot of gravy
and they also eat a lot of sour cream
and a lot of butter when you put those
things on your potatoes that isn't the
potato that's making somebody fat it's
all the fat that they're putting on the
potato so but we can see the basic logic
that that it is a calorie density isn't
the only factor here it's just by far
the major factor so there's other
factors for example whether the food is
cooked whether the food has been
pulverized into a powder reconstituted
in other words a food that has been
ground up like a smoothie for example a
fruit smoothie is not the same thing as
the whole fruit it's close its close but
it is actually a more fish
mechanism for getting calories then the
whole fruit and therefore it's
effectively probably 10 to 12 percent
more calorie dense so a smoothie is
really a figure at 330 calories a pound
where the whole fruit or fruit salad
would be 300 obviously neither one of
those is a problem because the fulcrum
is at 700 so this is you know the the
the conversion ratios and rates about
what what is converted into what in the
body those things are being worked out
better all the time by research so
carbohydrate will in fact convert in
fact it won't convert as efficiently as
fat will convert into fat but it will
convert and that's why a lot of vegans
when they when they eat a high
carbohydrate diet that is processed
carbohydrate bread crackers popcorn is
essentially a very dried carbohydrate at
1400 hours a pound these are ways to
keep weight on people and those
carbohydrates will convert at some level
of efficiency into fat so we are eating
a diet even if it's carbohydrates which
are very friendly to the body in terms
of their general toxicity so they can be
very healthy let go a healthy bread can
be a healthy food but the problem is it
can be 16 1700 calories a pound because
it's very dry and it's also pulverized
and so these are ways for healthy
conscious vegans to be carrying extra
weight on themselves and and be
sometimes mystified as to why because
they believe they're reading very
healthy food they are eating healthy
food at a biochemical level but they're
not eating the optimal food or the best
strategy for optimum weight so those are
some of the issues but I hope I think
all everybody is getting clearer and
clearer on as we go forward well great
thank you so much so one of the things
people were also concerned about on the
summit was this concept of nutrient
density and so somebody had posted on
the Facebook page a bag of these
Masaki sweet potatoes which are my
favorite you can get them at Trader
Joe's they're delicious they're similar
to the Japanese sweet potatoes at the
longest-lived people the Okinawan eat
something like 72 percent of their
calories from the whole three pound bag
has less than 1200 calories I eat a
whole bag a day less than because less
calories than a bag of M&Ms at the movie
theater and this person was all freaked
out because some blood wasn't even a
medical blog was like oh he's don't have
as much nutrients as the orange ones and
so I can't eat them anymore and so we
got a question from a really sharp guy
who was watching in with Vic he's a
college student he's 21 years old he's a
big fan of yours and he is a hyper
conscious nutcase self-professed and he
says dr. Lyle
it's amazing to me to see everyone
worried about developing all sorts of
deficiencies like fatty acid deficiency
protein deficiency calcium deficiency
etc even though there are no documented
cases of these and the scientific
literature or they're always worried
that they're not getting all the
nutrients they need when in fact the
real problem is we live in a country
where people are suffering and dying
from diseases of dietary excesses I
remember you saying somewhere that our
brains are evolutionarily designed
specifically to fear and worry about
deficiencies not excesses and I found
your insight into this fascinating could
you please talk about this and then
maybe also talk about why we don't have
to be worried about what color the sweet
potato is why bark when you have a dog
this young man said he's exactly right
this is a I just love to hear these
words coming from somebody else yes the
hopefully the echo chamber has started
yes we don't need to worry about
deficiencies there's there's one
deficiency that John McDougall worries
about which is b12 there's two
deficiencies that dr. Alan Goldhamer
worries about which are b12 and vitamin
D and past that you don't really have
any evidence to be worried about much of
anything so the let me think about how
to say this the the body is beautifully
designed to deal with nutrient
deficiencies there was it well if it
turns out that somehow by chance your
diet is
relatively low in some nutrient but the
DNA knows how to go about recycling and
conserving that nutrient so that you
don't wind up with a deficiency so the
only real deficiency that human beings
ever had to be concerned about would
have been just enough food that was the
problem and so I do believe that the
human mind is designed to be worried
about essentially being deficient in
food that's a hunger Drive and has a
very strong predilection to be thinking
and scheming about food now I believe
that that sort of culturally it's easy
to translate that worry about getting
enough food into getting enough worried
about worrying about constituencies of
food so ever since we started learning
about that there was constituent parts
of food that everybody has been worried
about those constituent parts in the
last 150 years the discovery of the
protein and then finally vitamins this
is now got people obsessed about getting
enough the young man is correct you
don't need to be worried about getting
enough the fascination with with new
with nutrient density to me is totally
misplaced I believe that you could eat
what we would consider a very nutrient
deficient diet quote unquote and be fine
the the issue is I think for example a
diet of just potatoes would be
outstanding and then if you fed America
just potatoes people would get way
healthier than they are now and any
nutrient deficiencies that would result
would be few and far between and they
would be minor so this is and obviously
you could get rid of those deficiencies
by throwing in a stalk of broccoli every
now and then and then it's over it's not
even close to a problem so this is this
is the the problem that we have is a is
a natural problem being mapped on to
modern knowledge in other words a
natural problem I've worried about the
efficiency in general of starvation and
then we map it on to starvation for
vitamin B for b12 for these six for C
for e for D
whatever it is essential fatty acids
okay pretty soon hyper conscientious
nutcases are worried about deficiencies
and everything they're worried about
deficiencies of purple phytochemicals
for God's sakes so we got to make sure
that we get enough of those this is just
totally ridiculous yeah it's
understandable in other words I
understand the nature of the psychology
that is driving it but it's misplaced
this is what I call looking for health
in all the wrong places but less you
want to look for health as as is the
young man suggested getting rid of
dietary excesses essentially
re-establishing appropriate natural
balances to your diet when the diet is
way out of balance then that then then
there can be problems but people's diets
now the balanced problem is not
efficiency the balanced problem is
excesses chiefly of excess calories so
excess calories in general is actually
probably the biggest single problem and
and I believe excesses of animal protein
as well as heated oils are probably the
the other other problems that are
causing imbalances in metabolic process
and resulting in health compromised nice
thank you
dr. mcdougal had said on the summit that
there's never been a document in case of
fatty acid deficiency but we have a
young lady Tami asking do we need to
supplement with DHA and EPA I think that
it may be possible that if you were to
be eating an extraordinarily lean diet
in other words you you just ate super
lean super low-fat foods and potatoes
and and I don't know maybe asparagus and
um fruit if you had an extraordinarily
lean diet that never touched an avocado
and never touched a nut of any kind
would it be possible when you didn't
need any oats because oats have about 15
percent fat so if you had an
extraordinarily low-fat diet
do I think it might be possible that you
might be able to get
some small small minor-league symptoms
not essential fatty acid deficiency per
se but but that you would function
better if you had a little bit more yeah
that's possible and so what would you do
then
if you really didn't want to eat a nut
or an avocado and you didn't want to eat
any oatmeal well you could take a little
bit of flaxseed and put it in a coffee
grinder and then sprinkle it on your
salad okay if you did that if he took a
teaspoon of that a day and did that that
would solve any any and all possible
essential fatty acid deficiencies that
would ever come up so that's that's a
solution I don't do such a thing because
I'll need a few nuts and I'll eat a few
avocados and I'll need oatmeal so I'm
not worried about it yeah I think the
real problem is the worrying about it I
haven't added any fat to my diet in
seven and a half years but there's a
blood test that I get every year at my
annual physical called the essential
fatty acid profile and it just keeps
getting better and better but I do eat I
do so but you know dr. MacDougall talked
about that Kon potato study where
somebody ate nothing but to a couple
actually ate nothing but potatoes for an
entire year and they actually had to add
oil to it because they couldn't get
enough calories and they had no
nutritional deficiencies so yes that
makes sense in other words the it's very
hard to engineer deficiency the the real
health problems are excesses so but
deficiencies are the worry that that's
the natural worry the species as you can
imagine no animal in nature evolved they
worried for having eaten too much but
every animal in nature has a constant
omnipresent fear of not getting enough
and so that that's why we see the
fascination with this is how you get
Prevention magazine this is how you get
the supplement aisle off the health food
store that drives the vast majority of
that that's the most profitable place in
the store so you can imagine that this
is also what drives the literature in
the health arena what's driving it is
everybody's worried about deficiencies
just efficiency worry I'm gonna
what when they dairy me again that there
will still be a crushing fear of
deficiency in a society that is
massively overfed and and that that's
because we will never we will never be
able to pull this concept out by the
root because it's rooted in human
natural history and were designed to be
making this mistake Wow well thank you
so much so this next question came from
many people watching the summit and I
just want everyone to know that when I
ask this question it's not because I'm
trying to put one doctor against the
other or be in a camp or disrespect
anything that was said on the summit but
it did create a lot of confusion and
that is two knots and again this is
deficiency so we have two ways to look
at it first of all well some of the
speakers were strongly believing that we
need nuts justjust for health just for
survival without them die prematurely
and being more at risk for things like
Alzheimer's heart disease and strokes
and so that created some fear in people
that had trouble eating nuts because
they found because remember this was the
real truth about weight loss summit and
there are people like myself that find
that we could not lose weight with nuts
or even with any added fat and so it
created a lot of fear in people so this
is a two-fold question do you believe
that we absolutely have to eat them for
optimal health nobody will die sooner a
heart disease dementia and stroke and
how do you feel about them for weight
loss or is it okay to be on the no added
fat diet and I'd like because people are
this is what people worry about right
okay
first of all about the first part is
whether or not nuts are useful in terms
of reducing your risk with respect to of
heart disease etc no they're not so the
there are no better and no worse than
any other whole natural fit so the
notion that the nuts have any documented
protective effect over and above the
fact that they would replace in some
people's diets they would replace for
example meat and cheese and so forth
so as a result if a person has a high
net consumption there they are going to
be eating foods that are going to be
they're now going to be subtracting out
other rich foods out of their diet and
the rich foods that they're going to be
subtracting out are gonna be steak and
cheese so you have to statistically
control for that fact when you look at
any of this evidence when you when you
look at the evidence from a more
comprehensive scientific perspective
you'll find that there's no evidence for
any special powers of nuts to help you
with respect to vascular disease for
example so that that's a
misunderstanding
I actually know the research that that
people are excited about there and I
understand how is that that a that an
individual could come to that conclusion
by looking at that research but that's
because that that analysis has not been
done in a comprehensive fashion from the
standpoint of statistical inference and
when you as a former stats professor I
looked at that question carefully and
the answer is definitive there is no
there is no evidence at all in fact it's
it's more strong than that in other
words the it the evidence is quite quite
substantial in other words the question
has been looked at quite carefully and
there is sufficient enough precision in
the the ability to analyze the problem
because there has been so much data
collected on the problem that there is
no question that there is no special
power of nuts okay so it's not simply
that I can say that there's no evidence
to support it I can say that there's
tremendous evidence that makes it very
clear that there is no special utility
of nuts to to help your cardiovascular
health okay so that problem we can put
away now the the next question was about
nuts and weight and that's our our a
high calorie density food they are the
highest nuts and seeds or about 25
or carries a pound typically so they are
the highest calorie dense food in nature
for humans and so actually I think in
nature in general I don't believe that
there's anything else in nature that I
don't believe would for termites is
higher calorie density in other words
would I think should be it's probably
thousand calories a pound if you're a
termite so because wood wouldn't have
fat in it the way that the way that the
nuts and seeds do so I believe that that
actually if we start thinking about
whale blubber that's gonna be probably
if you're a shark and you eat whale
blubber
that's probably higher calorie against
it even nuts all right so I'll quit
speculating back at different gallery
densities the the truth is is that that
nuts and seeds are gonna be the the
highest calorie density plant food that
you're ever going to have the
opportunity to eat as we would expect
then we wouldn't expect them to be
immune from the fact that the higher
calorie density the foodstuffs are the
more fat the animal will store on its
body so as a result we would expect that
if you add nuts - somebody's diet that
their overall you know fat profile is
going to increase and that's how that's
going to work so if you eat a few nuts a
day then we would expect all other
things being equal we would expect you
to be slightly have slightly more fat on
you now let's suppose that you eat
announcing that today because you're
worried about some kind of a nut
deficiency problem if you were to do
that that would be little enough nuts
that the ability to detect a difference
in your body weight would be very
difficult to do and after a year of such
a practice we might find that you're
only one pound heavier and that may be
what it is that you sit at you know
indefinitely if that's your practice if
you add two ounces and that's it might
change it might be two pounds heavier
overnight before we don't know okay so
now we start to wind up with
interactions with your personal genetics
and it would be impossible to determine
but we would know for example if
take a hundred people and we would
suddenly have them each eating two
ounces in that today and where they had
previously not eaten so we would find
that statistically the average a year
later those people would be heavier they
would be a little bit fatter probably
not a lot because that would be a lot of
food but it would be enough it would
increase the average calorie density of
their diet because the calorie density
of nobody stuff is 2500 carats of panel
so even somebody that's eating trash
with both hands their calorie density
their diets probably 1,200 care this
account so if you add a little bit of
nuts we're gonna start dragging it up to
1300 and we're gonna add a little bit of
body fat so that's the story on that
sigh I have no objection to nuts
I will tell people that if they are
overweight in their attempting to lose
weight and get very fit that that may be
one thing that they're probably gonna
want to sacrifice or at least largely so
along with any other high calorie
density food that they're reading more
processed food in no circumstances would
I ever tell somebody that they needed to
eat nuts in order to reduce their
vascular threat now that's a that's a
misunderstanding that hopefully we can
we can lay that with the rest well
people are still worrying not just about
the stroke risk for heart disease risk
with the dementia risk and the water jet
risk because that's what they're being
told Debbie sank she started skipping
nuts and to me she she can tell the
difference but do you think that the
weight loss is the same for everyone so
in other words are there people that
just will lose weight quicker and easier
without the fat because if you're eating
fat I mean isn't it easier for body to
take the fat if you're not eating fat
from your body does that make a
difference um I don't think of it that
way you just think of it as overall
calorie density balance so if you're
it's not about whether you're eating fat
or not eating fat per se it's about
whether or not you're the overall
calorie density issue is involved and
also how much a person is eating so our
our point here you can lose weight
eating a very high fat diet if you eat
two bits of it and then you why are your
jaw shut and you
you feel like you're starving to death
you can do this people people do do such
a thing
the what we want to do AJ is we you and
I have always talked is we want to lose
weight without losing your mind
yeah you want to simply eat a calorie
density balance of your diet that is
consistent with your natural history so
it feels very comfortable that you're
that you're not fighting the hunger
Drive and yet the calorie density of the
diet is low enough that that it's
probably but 700 or lower which means
it's basically full of whole natural
foods and not a lot of rich foods in
that in that arena so that we wind up
getting lean and fit and yet we're
comfortable so that's the the issue is
not actually but dr. Alan Goldhamer died
at true north is actually a little
higher fat than the MacDougall diet
interestingly enough so the Alan's a
little looser on some of the fat content
and yet both of those diets will work
fine just because they're both within
the parameters of the natural history of
the species so I'm not too worried about
about some of the fine details here I'm
interested in getting the big picture
right if we get the big picture right
we'll be fine it's just the people that
I work with that lost weight not eating
nuts when they reintroduce them they all
gain weight and so I think of something
like myself who hasn't had not seen
avocado in seven and half years yes I
started including them because I was
worried I was going to die prematurely
or get dementia I would have to take
something else out of my diet and I'm
thinking I don't want to I mean I don't
want it less potatoes or less sweet
potatoes or less rice so it just seems
that when you're eating foods of a
higher caloric density you can't eat as
much food yeah so duh
however you're designed by nature to be
comfortable the higher calorie density
foods impact Society mechanisms more
more intensively than lower calorie
density foods so as a result yeah you
would be able to eat less food if you
eat foods of higher calorie density but
you'd be satisfied in doing so the the
problem begins when the overall
calorie density of the diet it's to be
higher than that of our natural history
at which point the the satiety
mechanisms aren't going off soon enough
and so you can only compensate so far
for a diet that is very overly high in
terms of its calorie density the system
won't won't allow you to be comfortable
on one pound of food a day if it's 2,000
calories a pound fitted so for example a
peanut butter jelly salmon which is
2,000 calories a pound and most women
burn about 2,000 calories a pound if
they were to eat one pound a day at
peanut butter jelly sandwiches they
would not be completely satisfied now
they'd be close and they wouldn't notice
it from day to day but what would find
what they would discover they were doing
if we watched them very carefully is
that they probably start eating 2,200
2,300 calories a day
so they wouldn't actually be completely
satisfied on the 2,000 well as if we we
dial the food away from the peanut
butter jelly sandwiches and take them
back to 700 calorie pound fair instead
of 2,000 CARICOM fair now the reading
almost three pounds of food a day now
they're comfortable and they're not
finding themselves reaching for an extra
two or three in their calories so that's
that's the issue issues essentially
carry density so everything comes down
to calorie density really knows about
higher calorie food because doctor
shintani
who actually I don't know if you know
this it was so fascinating he bought dr.
MacDougall's practice for $1 he was just
wonderful to me he said that people feel
more satisfied with that because of the
greater caloric density that's I think
there's anything specially satiating
about fat it's just that it's a higher
Lori that's food right so for example
you would feel more satiated on on one
ounce of fat than you would on one ounce
of carbohydrate okay but the issue is
that that's really he is correct there
but that's that's not the fundamental
issue that we're looking at because the
question is whether we are more
satisfied on half a pound of food or a
quarter
the food and the answer is well it gets
complicated okay we have to now add in
the calorie density because if it's a
quarter pound of fat versus a half a
pound of carbohydrate it's gonna start
to get close that's what's going to
happen but what we'll find is is that if
the overall calorie density of the diet
starts creeping up past 700 what we're
gonna find is that people will start to
systematically overeat and that's what
being fat is having excess fat as a
result of the systematic of reading the
person in other words just I don't
believe in the conscious regulated
regulation of food intake I think that
that's an absurd concept weighing and
measuring etc just doesn't make any
sense to me it's not done by any animal
in the animal kingdom and it was never
done by humans until the 20th century so
the the concept of needing to
consciously monitor your food intake is
as ludicrous as the notion of being able
to consciously monitor your oxygen
intake so we don't want to be in the
game you can do both by the way you can
you can pay attention to your breathing
all day long and try to not take a deep
breath you could do such a thing
but it wouldn't do you any good in the
long run because pretty soon you're
going to slip into unconscious
consumption of oxygen in the same way as
you're fitted so you can be fastidious
as all hell
but sooner or later you're going to slip
into unconscious consumption and so it's
really going to be whether or not the
nature of those materials the nature of
the food enables you to unconsciously
regulate accurately and that's really
what the issue is and so the issue is is
your diet higher than it should be
naturally in terms of its calorie
density if it is mmm you better have
good genes or you'd better have genes
that can that can manage that or else
you're going to get excess weight I love
how you said on episode 161 of the beat
your genes podcast that only 1% of
people that are thin earned it and that
people that have never had this problem
do not understand the difficulty of it
I mean all your work is great but
episode 161 if they gave Oscars for
podcasts that episode everybody must
listen to I've listened to it seven
times I'm not kidding it's it's
brilliant so everyone please listen to
that and also please stay till the end
of the broadcast because dr. Lila I
actually have a an announcement that
we'd like to tell you so just just to
recap if I got this right that's for a
whole natural food they're healthy but
they're of a high caloric density and if
somebody wants to eat them that's fine
but they don't have to feel like they
must eat them for longevity or
prevention of any of these diseases and
that could carbohydrate bits are not
evil as worthless as we a lot of people
feel that nuts are the superior
superfood and that we should be eating
those instead of things like potatoes
rice etc what all correct it you've got
it
great okay so I'm gonna get to a
question that came in because we have
some speakers well at first of all no
one said caffeine was good on the summit
it's just the degree of some thought it
was actually worse than others in the
reason so we had a question dr. Lyle
what is it with coffee what is the
attraction to it and why am I having
difficulties letting go of it I really
do not even like the taste I switch to
decaf for three days so far any
suggestions or alternatives and so the
people are having a really hard time
letting go of caffeine and work it's not
a health food so take it away right what
what caffeine does I mean it's there's a
multitude of effects of caffeine but the
but the couple of effects that were
interested in is it there's a specific
neurotransmitter adenosine I believe
that this what the name of it that that
causes you as it builds up inside your
mind as you go out go through the day it
causes you to feel sleepy that's its job
in other words it's a signaling
mechanism
yeah it's essentially like hmm let me
think about this let's suppose that you
there's probably there's many such
mechanisms in nature but what's the
you had a device on your car that could
measure the dirtiness of your oil and so
we don't have that yet but you know that
could be coming in the future the that
as your oil gets dirtier and dirtier
from the from the work that it does to
try to keep your engine clear and
lubricated that as it gets dirtier you
find you a little meter goes on and
tells you that your oil is getting too
dirty and now you've got too many
particles in there and now the oil is
not able to do its job to stop the wear
and tear from the little particles that
are circulating in the oil from debris
well your brain also gets dirty so the
longer you run your brain in a day
you're essentially dirtying up the oil
and as a result what's gonna happen is
you need to know you need to have a
device to tell you that you're actually
that your brain is dirty it is
essentially polluted and that device is
adenosine or you know what somebody's
gonna say that idiot doesn't know how to
pronounce it
pronounce it the but the point is is
that it's this it's a neurotransmitter
that is a signalling device to tell you
that your brain is dirty and the way you
fix your brain the way you get your
brain clean is to go to sleep
and that's what happens when you sleep
it's a time for your brain to clean out
and does a bunch of other things sleep
there's a bunch of other things that we
now understand that we didn't know 20
years ago but it's a chief mechanism of
sleeping is the cleaning of the brain
and so when you use caffeine it blocks
the action of adenosine what it does so
you don't feel it so you don't feel
sleepy even though your brains dirty so
you can see what kind of a problem this
is this is the equivalent of if you have
a sprained ankle that I give you a
painkiller in your ankle so that you
can't feel the spring so you walk on a
foot that's damaged when naturally you
wouldn't be walking on it now we can all
see a reason why this could be useful so
for example if the Romans are attacking
your fort and it's incredibly important
that you stay awake and
don't you know that as a century then
you could see where coffee would be a
good idea because you would keep you
awake even though your nervous system
was telling you that your brain was
dirty and you should go to sleep you
could make use of that except you have a
perfectly good chemical for that anyway
it's called adrenaline so you have a
pressure at work or some big thing and
yet you're short of sleep that's okay
yeah if depending upon how important the
issue is your nervous system will kick
out sufficient adrenaline to keep you
awake to the appropriate amount of time
to run a cost/benefit on how important
is the issue versus how important is the
sleep and you know when you when the
brain becomes sufficiently dirty when
you've gone 22 hours and your
presentations four hours from now it
will finally have you go to sleep even
though it's very hard for you to go to
sleep because you're full of adrenaline
but the mind will be brilliant at
finding that cutting point and deciding
you know what your brain is too dirty
you're now becoming dysfunctional go to
sleep okay now however you could subvert
that with coffee and you could block the
action of that and now what's going to
happen is you'll wind up with
compromised abilities and it's an
inefficient way to go what's happening
so that's one thing that's going on so
people don't like the feeling in the
morning that they're short of sleep
they're short of sleep because for
various and sundry reasons the electric
light bulb and interesting things to
look at it on on lit lit screens have
kept them up past an appropriate bedtime
now they're short of sleep and now they
feel sleepy their brains dirty they're
starting out the day with a dirty brain
and so what are they going to do and
some of our brains are dirtier than
others but the point is is that you're
starting out the day with a dirty brain
and it doesn't feel good and you're
being encouraged to go to sleep by your
biology so what do we do we go to
Starbucks and we block the action of Vin
Sun and now you feel better but actually
you're operating on a dirty brain this
is you know this isn't the greatest way
to live it's a
effectively artificial adrenaline and is
it is it terrible no it's also addictive
in other words once you once you do this
over and over again the the the brain
obviously gets used to it and
anticipates that it's going to have it
and then builds up defenses against it
because it wants to operate around any
kind of chemical action like this
whether it's morphine heroin you know
teen or it's caffeine which the
brain will try to wrap its way around
and figure out a way how to defend
itself against it and as a result we
wind up with tolerance and so then
what's going to happen is if you
frustrate system by not giving it the
drug winner that expects you're going to
go into withdrawal it's not going to be
pleasant so which rahl effects are going
to keep people in the trap and it's
going to be sometimes hard to break an
addictive cycle like that
that's the pleasure trap caffeine is a
minor-league version of the pleasure
trap it's not particularly damaging it's
you know now we're gonna discussion
between myself and my co-author you know
Alan Alan could could could recite for
you a litany of evils associated with
caffeine I won't in other words on the
grand scheme of things this is what I
call one of the minor sins so it's a
little bit of a problem but it's not
nearly as big a problem as that she's
sandwich Wow okay it's just on the on
the summit we had some doctors giving
some evidence why it can cause people to
store body fat and since this was a
weight loss someone trying to give
people other tools that the places to
look you know if they were still
struggling but it doesn't seem to be
help for people that's interesting idea
I never thought of that
and never occurred to me that that would
be true so this is information I've
never heard before I can see the
possibility of a chain reaction looking
as follows
I could see how research might suggest
that that would be true
the possibility of chronically sleep
deriving people behind caffeine use when
people are chronically sleep-deprived
they are they are less active and less
likely to exercise and as and they're
probably more likely to reach for
stimulating fits so I can see that
caffeine use would be more
comprehensively and subtly disruptive to
healthy living
and as a result and thereby contributing
to weight gain but how caffeine
specifically would act on that bad
that's outside my knowledge okay well
I'm gonna see if I can get you a copy of
that talk maybe you would look at it and
look awesome so while I well I while you
were talking I googled the calorie
density of whale blubber and wood just
so you know if you're trying to lose
weight you'd be better off eating wood
because it's less than 1 kcal per gram
they said it's between zero and one
whale blubber on the other hand is 247
calories per ounce or three thousand
nine hundred and fifty-two calories per
pound so it's it's right up there with
oil it's a hundred percent fat so we
don't regular fabulous now we no
definitely don't recommend it so there
was a comment live I can't find it right
now but this is the same thing as one of
the questions we have somebody was
talking about cravings and for that I
actually recommend they watch your
crammed circuit lecture which is
available both on my YouTube page and
dr. McDougall site but this lady says
this is a question about self sabotage
dr. Lisle dear dr. Lisle I find I
sabotage myself several times a week
with salty tortilla chips and guacamole
or eating out or oil and salt are
embedded in the food what are good ways
to work on self sabotaging I would just
say don't eat out yeah I mean she's
asking the the question it's a it's a
good question but the but I can't give
you a snappy answer because the truth is
is that the problem is comprehensive
that's why Alan and I wrote a 240 page
book on the problem the you you're
designed by nature to seek out the
richest food in the environment and so
the you're designed to actually run a
cost
benefit on how much energy you're gonna
put out to seek out how rich your food
so you can imagine for example the
following scenario if there's a if
somebody has a fruit salad in front of
you but over you know 20 feet away
somebody's baking up some potatoes and
beans and you you are you're
sufficiently hungry you're just not
feeling like nibbling on something you
actually want something more substantial
so the fruit salad does it doesn't have
the richness of the potatoes and beans
that are being cooked and so you find
yourself drawn to and you'll get up off
your Duff and walk over there and see if
you can get some of that okay that would
make sense the higher calorie density
will draw you to put up physical action
in order to get it now let's suppose
that there's a tree on the other side of
the river that grows Snickers bars so
it's a snicker straight and Snickers bar
tree that's 2,500 calories a pound on
the Snickers bars and they you have
traded with the people down the down on
the other side of the river
from time to time it's a 17 mile hike to
get to a crossing but you could in fact
swim across the river now you're you're
not in the river is pretty cold so it's
kind of unpleasant but that's not the
biggest problem the biggest problem is
that there's piranhas in the river so
question is you know you might get lucky
that you've seen animals swim the river
and not get attacked by the piranhas but
you've also seen some animals in the
river that did get attacked by the
piranhas so now the question is you you
can see that the Snickers bars are in
fact in season you can look across the
the 40-yard River and you can see that
they're there and they're nice brown
wrappers with the blue lettering I think
yeah
so the question is will you swim the
river to get a Snickers bar and the
answer is no you're not
so are you tempted yes you might be
tempted you don't want to even let your
children know what a Snickers bar is
like because you don't want them going
in the river after this forget
about the province so the question is
not how it is that you sort of get rid
of this this tendency because you're
going to be drawn to high calorie
density foods for the rest of your life
that's just part of the nature of all
animals to do that question is will you
work hard enough at setting up your
environment to make it statistically
less likely for you to act on that very
often this is what aj is talking about
don't go out to dinner which means you
want to have competitive food already in
the house that's easy easily available
so that when you have the impulse to to
taste tortilla chips and and beans and
guacamole then you've got it all ready
at home so you've got tortillas there
and you've got beans there and you've
got avocados there and you may have some
low-sodium salsa there so you can
actually get that taste and it's going
to take you 10 minutes or so to get that
all together but you can do that and and
make that competitive so even though
going out has a lure that it's saltier
and it's richer and it's fatter and that
you don't have to do anything except sit
and there's a pleasant ambience of
people around talking in other words
there's and there's margaritas and there
was there's things that will also draw
you there but what we want to do is to
make it as competitive as possible to
make healthy choices and so you start by
setting up your environment in a way so
the healthy choices are highly
competitive with the pleasure trap and
in doing so you make a chance for you to
get in a nice groove great thank you so
we have a question from somebody
watching live I took a screenshot
because I can't see worth a darn anymore
from Brooke and the part that I'm really
interested in is the last sentence
because I hear this a lot but she's
saying I should pay Jay I really wanted
to ask you a few questions but I have
you answered I've lost an amazing 80
pounds following your book but I also
used intermittent fasting or I ate only
in a four-hour window usually from 6 to
10 however I know I need to have more of
a gap between finished eating and
sleeping my problem is that once I start
eating I can't stop
so she's afraid if she starts earlier in
the day she won't stop like if I was
answering this question I'd say that
that's a ridiculous window and that's
what's making her not be able to stop
because she's because even dr. Goldhamer
said he is really against this one meal
a day phenomenon that people are having
such a narrow window but I hear this a
lot from people so I can't discount that
that even people eating whole natural
food without the nuts in the avocado
that they feel like they can't stop
eating when I talk to them it's usually
because the starch is too low and
they're trying to just fill up on fruits
and vegetables so what do you say to
broken what do you say to these people
that claim then on the diet we recommend
they just can't stop eating once they
start yeah I would I think you you've
got all these little elements in that
and what you just said you talked about
a lot of things we probably have we've
got a conditioned cram circuit so we
would I would suggest that person go
back and watch that that webinar that I
did with I think that was Gustavo back
in the fall of seventeen I think this
one that was I can't remember that
should be on the mcdougal website the so
she's conditioned to cram circuit by by
every night she's eating a great deal in
a short window what do I think about
intermittent fasting not necessary not
particularly useful the I think that I
think the utility of internet and
fasting is a concept when people have
used it and it seems to have worked it's
been predominantly to chop off a
conditioned cram circuit kind of
accidentally is how that's worked so I
years ago when I was a youngster I read
a book by dr. Wayne Dyer and I don't
remember what which it was it might have
been your erroneous zone sir might have
been pulling around strings I can't
remember it might have been a third one
the that he said something in there that
struck me as really useful and that he
said first be a good animal and I
thought good for him is I mean this was
before I knew much I knew a little bit
about nutrition at the time but not much
but basically he said you know you
healthy foods you know eat when you feel
like eating don't eat when you don't
feel like eating go to sleep get some
exercise etc what he's really speak was
speaking to is the notion of getting a
decent balance and so that's how I would
inform you about how to deal with this
the what I would suggest to somebody
that's trapped in trapped in an unusual
thing like like the skels doing if she's
heating four hours a day and she's
probably eating pretty intensively those
four hours a day if it's working for you
and you're comfortable with it then I'm
not too interested in disturbing it I'm
not interested in telling you that it's
the wrong way to do things it's a way to
do things and if you're comfortable and
it's successful as long as you're eating
healthy foods then this is not a problem
it seems to me that you might be more
comfortable distributing your calories
out across the day and not eating so
intensively in one shot maybe maybe not
most people are more comfortable eating
two or three times a day maybe more just
and as well as long as you are eating
whole natural foods to be a good animal
and simply follow your instincts as far
as that goes you don't need to be
pushing your food within a feeding
window that doesn't make any sense I
want to point out that that's that would
be inconsistent with animal history you
won't see animals do this they don't eat
in feeding windows the koala bears don't
say oh it's 2:00 in the afternoon that
said we're done it's a penis okay so
they follow a natural rhythm so try to
establish here for yourself the natural
rhythm and that's how I would tell you
to go about that problem okay thank you
I think we have time for one more
question before the big announcement
it's from Kiki who's watching live she
says do you believe in this new disorder
of orthorexia because so many of us that
eat this way were told that for so long
I think orthorexia that's the notion
that people are just overly fascinated
and worried about what it is that the
reading is that google it but I think
it's good
Kancha snis or maybe they feel like it's
an eating disorder because we're so
focused on what we eat and what we don't
eat right I think that's what it is
the now what do I think about that the
would you like it right now it's saying
it's a term for a condition that
includes symptoms of obsessive behavior
in pursuit of a healthy diet or the rec
suffers often displayed signs and
symptoms of anxiety disorders that
frankly co-occur with anorexia nervosa
or other eating disorders yes you can
you can describe you can describe a lot
of these behaviors under the umbrella of
OCD and so the CD is a it when we can we
can call that a disorder because it's
you call something a disorder because
it's it's causing you more trouble
minutes than it's helping you so that's
that's what we would that's what we call
a disorder so we we call something a
substance abuse disorder when the use of
the substance is now got the person's
life out of balance to the level that
they're not just having a glass of wine
now and then but they've got a problem
with alcohol so now we call it a
disorder so the the gods of Psychiatry
decree that something is a disorder when
it's you know essentially more more
trouble than it would be worth you could
you choose not to have it the let me
give you an example of another disorder
so and some of these disorders are
clearly sort of genetically problematic
or otherwise pretty serious
business so if you have schizophrenia
that's called a formal thought disorder
and that's pretty pretty rough okay
that's a disorder the what they'll call
disorders is a matter of a committee
okay so now we've we've decided that
that there's a that there's a committee
of that were that would they say okay
we're dealing with people that seem to
be overly obsessive about the health of
their food well if you were to have
something that anybody would cause
called a disorder that would appear to
be about the most useful disorder that
one could have okay okay and the fact
that there may be a a sort of overweight
self-indulgent wine connoisseur
physician on the other side of this
diagnosing it may be a rather
entertaining for some of us that are
taking a thousand foot view and looking
down on this scene so I would say that
it would be essentially appropriate for
people today to be somewhat what do they
call it orthorexia in other words we
should all be more conscious and
cognizant of our food choices and the
impact on our health than we are as a
population now that does that is it some
though they're as useful to say that
there are people where it looks like the
the benefit from being from doing so is
greater than the cost or that the cost
is greater than the benefit yeah I think
there is in the same way that there's
people that are that are concerned about
germs on their hands which is a
legitimate thing to be concerned about
but they're overly concerned and they
wash their hands too much and we would
call that obsessive compulsive disorder
with a germ phobia and so and so yeah I
I don't I don't deny that we can say
that this is a OCD variant
it's it's an extraordinarily benign OCD
variant we wouldn't treat it the last
thing we're gonna do is have somebody we
could treat it we would try to treat it
with knowledge and that's one of the
things that I try to do is I try to
explain to people that that the that
healthy living is a very good thing but
hyper healthy living is probably not
going to benefit you very much past
healthy living if at all so that these
it's useful that actually a cure for
orthorexia is knowledge so knowledge of
understanding that subtle variances in
behavior in health arena are not going
to have any appreciable measurable
impact whereas large differences will so
don't get in the same way that OCD
people need to learn that if they wash
their hands six or eight times a day
they're not going to get deathly ill but
they're washing them 25 times a day and
so they're they're actually chafing
their hands and they're going to be
better off if they don't they also need
to you know knowledge is power that or
they need to learn an experience that
they can loosen the reins a little bit
and be okay so yeah you could you could
give this a name if you wanted to I
would just call it I have my own name
for a hyper conscientious nutcase
and it and it turns out that my hyper
conscientious nut cases are very often
in and around food and I try to talk him
off the ledge and realize it that if
somehow a frito sneaks into their mouth
every now and then that this is not a
disaster and they're not going to die
from it and it's also true that they'd
very often they're not just hyper
conscientious about that but they're
hyper conscientious about other things
as well they tend to be extremely
responsible people in many dimensions
and and spend and have a fair amount of
anxiety about being perfectionistic so
this all goes under the the Hat
perfectionism and you will see
perfectionism not only in orthorexia
you'll see it in anorexia you'll see it
in bulimia and you'll also see it in in
in hand washers and people that check
the
stove 50 times before they leave the
house this is a characteristic of my
people near and dear to my heart
hyper conscientious nutcases who I have
to be surrounded about in my career and
talked to one right now it's almost as
if with this hyper country and just
eating we've gone full circle because we
started out talking about nuts nutrient
density which is sort of an example of
that something else to beware as it
works yeah that's right 800 well you
guys I have a really big announcement so
if you really enjoy talking to dr. Lisle
and having your questions answered by
him what if you could do that on a
weekly basis so what happened is I
recently taught a 13-week class based on
my book secrets ultimate weight loss and
one of the weeks I was speaking on a
holistic holiday and sea cruise and
while I had internet I couldn't trust
that it would be good enough to give a
one-hour talk in the middle of the ocean
and so I asked dr. Lisle to fill in for
me and the class went nuts and they
loved having him as a guest speaker and
they said could dr. Lau please do this
well I asked him and he doesn't have 12
weeks of his life to do this but he said
he would consider doing a six-week
course based on his book the pleasure
trap and I'm gonna just put a link right
here where you can register now there
this class will be limited because we
can only get a certain amount of people
on this technology but it's really
reasonably priced it's less than $100
for six weeks of having dr. Lisle teach
this master class on escaping the
pleasure trap based on his book you'll
get a PDF of the book and you'll get to
be with him for six consecutive Monday
evenings at 5 p.m. Pacific time starting
on Monday April 22nd part of it will be
lecture based on the book and part of it
will be Q&A but what's really great is
that he is going to include material
that he didn't have when he wrote the
book so it's gonna be a fabulous class
we have we have so many people
registered already because we did open
at first to the people in the class and
almost all of them signed up so I hope
you guys will check it out because I'm
taking this because what could be a
better way to spend Monday night so I
thank you so much for doing this
it's gonna be that's just another wacky
fun AJ thing yeah yeah I'm always in
right so if you're a hyper conscientious
in that case we expect you to sign up
immediately well thank you so much dr.
Lyle it was great talking to you about
these these things and thank you guys so
much for watching I'm chef AJ and I make
healthy tastes delicious but dr. Lyle
makes it understandable don't forget to
watch episode 161 of beat your jeans
take care everyone
