entheos.com The Calorie Myth 1
Jonathan: Hey, everyone. Jonathan Bailor back with, brace yourself, we
have got one of my personal heroes and one of the pioneers in
the field of let's call it modern nutrition and exercise science or
thinking beyond just oversimplified calories in, calories out. The
inventor of the Zone diet, the amazing researcher, Dr. Barry
Sears. Welcome, brother!
Dr. Sears: Thank you very much.
Jonathan: Dr. Sears, there's so much we can cover today. I was hoping
we're focusing on the beautiful complexity, but it's still simple
when it comes to actually using food and exercise to heal
ourselves, and you really broke through, in terms of thinking
about food and exercise as a control system for your hormones
a few decades ago.
I wanted to cover that. You've since made dramatic
advancements, but I want to start the viewers on your initial
breakthrough that predicated the Zone diet, which is food and
exercise is a control system for hormones a bit more than it is
about counting calories.
entheos.com The Calorie Myth 2
Dr. Sears: Well, actually much of it comes from my background, which is
not nutrition, but really intercalary systems for cancer drugs.
When you deal with cancer drugs, if you give too much of the
drug to the patient, they die. You give them too little of the drug,
they basically die of cancer. You try to keep that drug in a zone, a
zone that's not too high, but not too low.
So it became apparent to me about 35 years ago you could apply
the same principles to both diet and exercise to keep the
hormones juried by both of them within a zone, a zone that's not
too low, where it has no benefits, but not too high, where it has
basically adverse consequences. That was the thinking that led to
the development of the Zone diet, treating food as if it were a
drug.
Jonathan: There are two—just to unpack that a bit. It seems like there are
two really important points for our listeners to understand—or
viewers in this case. One is the focus on hormones and why that
matters and then also the focus of balance and how keeping our
body in balance—a lot of people think they need to balance
calories, but it seems like the body may have an innate drive for
balance if we just facilitate that. We talk about hormones and the
body's desire to balance itself.
Dr. Sears: Yeah, it is. This really was called medically homeostasis. The body
strives for basically consistency. The more you work with the
body, the better you two are going to coexist. The more you work
against the body, bad things are going to happen.
Jonathan: When you say working with the body versus working against the
body, I've always perceived starving yourself. If you feel hungry
and tired and terrible, that seems like the body might be saying,
"Hey, you're working against me." Is that a fair assessment?
Dr. Sears: That's a very fair assessment. The brain upstairs is basically
desperate. That's why you're tired. That's why you're hungry. It's
running out of fuel. What you basically had not done was either
make the right combination. Let me use an example like a car,
entheos.com The Calorie Myth 3
which is a very good analogy. You can't run a car on gas and you
can't run a car on air. You need some combination. The better
the combination, the better the mileage. That's what you're
trying to do with diet, to get the right balance of protein,
carbohydrate and fat to get the best hormonal mileage out of
each meal.
How do you know? You have a very simple metric. Your watch.
Five hours after you've eaten the meal, if you're not hungry, you
have peak mental acuity and you're not tired, your last meal was
hormonally correct for your body. Your goal is to find which
meals give that five-hour window of peak balance and try to
maintain that as your guide for the rest of your life.
Jonathan: All throughout this, Dr. Sears, you've been talking about
hormones, the correct hormonal fuel, the correct hormonal fuel.
I would assume then I might eat something that has 500 calories
and five hours later not feel great, and I could eat something that
has 500 calories and five hours later feel great. What hormonally
is different about those two experiences?
Dr. Sears: Well, there are a number of hormones that take place. Again,
let's look at the three primary hormonal systems that are
controlled by diet. One is the hormone insulin. If you eat too
many carbohydrates, the hormonal levels of insulin go up. That's
the hormone that makes you fat and keeps you fat. Now, so you
need some insulin, but not too much.
The hormone glucagon, which is stimulated by the amount of
protein at that meal of you also basically need that because that
releases stored energy. You have a tremendous amount of
stored energy, but you have to release it and that's what gives
you the five hours of appetite suppression, and that's controlled
by the amount of protein you eat at your previous meal.
Finally, there's a hormone called eicosanoids. They're the
hormones that control not only inflammation, but really they're
the hormones that control all other hormones of your body.
They're dictated by the balance of Omega-6 to Omega-3 fatty
entheos.com The Calorie Myth 4
acids. You're trying to keep those three hormonal systems in that
zone for the next five hours. Once you find out what is the right
balance of protein, carbohydrate and fat that you can live with
for a lifetime, you're well on your way to at least be having a
longer and better life.
Jonathan: I don't know if it's intentional that we've been using the window
of five hours, but it makes me smile a bit because we hear so
much about five hour energy and the five-hour energy drink. It
seems like if we're eating a hormonally balanced meal that keeps
us in the zone, there would be no need for a five-hour energy
drink. We will just have five hour energy.
Dr. Sears: You took the words right out of my mouth. It's not me talking
about this. This is actually data from Harvard Medical School. The
hormonal changes caused by any meal will last about five hours.
That's both good news and bad news. The good news is that no
matter how bad your last meal was, five hours later you can
rectify all the hormonal damage. The bad news is you have to
basically, every five hours for the rest of your life, make another
decision of what I'm going to eat and how that's going to dictate
how I will feel for the next five hours.
Jonathan: You've been helping people to find that balance for many
decades now, Dr. Sears. What are some of the concrete
guidelines you've found? Obviously, this needs to be customized
per person. I would imagine a 65-year-old, postmenopausal
woman will need to do different things to stay in the zone than a
15-year-old male football player in high school. But what are
some of the common denominators and then what are some of
the differences?
Dr. Sears: Well, one, there aren't that many differences.
Jonathan: Okay.
Dr. Sears: It turns out that whether you're an elite athlete or basically
someone just hanging on by their fingertips that the hormonal
entheos.com The Calorie Myth 5
rules haven't changed in 40 million years, and they probably
won't change tomorrow.
Now, the young athlete is putting a greater stress on their body
so they have to take that into account. But the hormonals for the
Olympic athletes that I've worked with and for the overweight,
type 2 diabetics are basically the same.
Here are all the rules you need to know because you only need
three things. Your hand. There's one hand. One eye and one
watch. At each meal, divide your plate into three equal sections.
On one-third of the plate, you put some low-fat protein. That can
be chicken or fish or if you're a vegetarian, it could be tofu or
soybean imitation meat products. I don't care where the protein
comes from, but that's no bigger or thicker than the palm of your
hand. That's about three ounces for an average female and
about four ounces for the average male.
Now what about the other two-thirds of the plate? You fill it until
it's overflowing with colorful carbohydrates. What are those?
Primarily vegetables and fruits. Finally, you add a dash. A dash of
what? Fat. What's a dash? A small amount. Just make sure the
dash of fat is low in saturated fats and low in Omega-6 fats. What
fats fall in that category? It could be slivered almonds. It could be
extra virgin olive oil or it could be guacamole.
Now, if you do that, how do you know it's working? That's why
you need the watch. If you hit the right balance, for the next five
hours, you'll have no hunger and complete mental acuity. All you
want to do is take the meals you like to eat, keep adjusting them
until those meals that you like to eat give you that five-hour
window of peak mental acuity without hunger. Now what you
have is a hormonal winning cookbook you can follow for the rest
of your life.
Jonathan: Dr. Sears, I love that you started this conversation talking about
how when you first approached this problem, as you continue to
approach the problem, you looked at it from a seeing food as
almost pharmacology and how you can then predictably use
entheos.com The Calorie Myth 6
food to manipulate the body in standard ways, just like you
would—like penicillin does this. It's not controversial. We don't
need to argue about it. We know it works this way. You have that
goal and you have that framework.
You mentioned in your overview just now, for example, you said
Omega-6 fats, not something you want to overdo, as well as
saturated fats. A very popular movement nowadays is this lower
carbohydrate, higher fat movement, which celebrates saturated
fats. Of course, that has different goals than what you're talking
about, but why did you say what you said about saturated fats?
Dr. Sears: Well, because the people in the, let's say, the new Atkins regimen
say saturated fats are good. Unfortunately, they're well-meaning
people, but they don't have a good background in the genetic
aspects of how fats affect what are called—there is sensory on all
of our cells. They're called toll-like receptors. Fats, saturated fats
basically are mimics of certain bacterial fragments that can
activate these toll-like receptors that send inflammatory signals.
It says, "Okay." Yes, Omega-6 fats are the worst you want to
remove. They're ubiquitous because they give rise to
inflammatory hormones. But make an effort of removing the
saturated fats and replacing them with monounsaturated fats.
Now it's been shown that if you do that, you get superior results,
but it's a lot easier to fall back saying, "Saturated fats are good."
They're not as bad as people are led to believe, but they're not
great. It depends on how much effort you're willing to expend
and how much the goal you want to achieve is worth.
I think that, again, a little science goes a long way, but in the area
of diet, science is usually the first casualty of war.
Jonathan: It seems like you classified fats maybe into three categories. Tell
me if you think this is fair, Dr. Sears. You have therapeutic fats.
Omega-3s it seems like would be classified as a therapeutic fat.
Monounsaturated fats seem like they're closer to that
therapeutic end. Maybe saturated are sitting somewhere in the
entheos.com The Calorie Myth 7
middle, and then the trans fats are on the far other end, and
then Omega-6 starts to fall more in that realm. Is that fair?
Dr. Sears: That's a very correct assessment. You're looking to say, "I'm
trying to get basically as much of the therapeutic fats in my diet
and minimize the amount of, let's say, deleterious fats. Once you
know what to basically say, "Okay, I've got good fats and bad fats.
Okay, I eat more good fats. I eat less bad fats."
Now, it's just not that simple because you still have a balance of
protein and carbohydrate to really control the flow of the fats
you do eat into the right hormonal pathways and say, "Oh, my
God. It's getting so complex." I say, "It's not that hard." But once
you understand yes, it's like a three-dimensional checker game.
You say, "Once I get the idea I've got to work in three dimensions,
it's not that hard." Eventually, it becomes second nature.
Jonathan: If I'm just—let's say I'm an individual who is with those colorful
carbohydrates. Let's say I do more vegetable-based and less
fruit-based so I'm not going to get many calories from that
source of my plate, and I'm sticking with the lean protein like a
fish or a chicken so I'm not getting many calories there. If I just
need to eat more calories so that I have energy, obviously we
would then go to the monounsaturated, but if I needed to do a
cocoa or a coconut or a grass-fed beef more as a source of
calories rather than a source of therapeutic nutrition, what
would be your thoughts on that approach?
Dr. Sears: Well, again, I'll speak with my work with the 25 gold medal
winners of the last five Olympics I've worked with. Again, the
difference between their diet and that of a type 2 diabetic is not
that great, except they need more calories. Therefore, they eat
more fat, more monounsaturated fat.
We've mentioned a couple sources of monounsaturated fat
which people like. Guacamole, slivered almonds, olive oil, but
here's a real easy one, probably the best source, macadamia
nuts. They're portable. They're little balls of fat and they're big
time energy.
entheos.com The Calorie Myth 8
I tell my world-class athletes. I say, "Just balance the protein and
carbohydrate. You really don't need that much more protein.
You have to basically make sure you don't overconsume the
carbohydrates, so eat lots of vegetables." It's hard to
overconsume vegetables.
If you need more calories, how do you know? You take your shirt
off. If you can see your abdominal muscles, you probably need a
little more energy, so eat macadamia nuts. Now if you eat too
many macadamia nuts, all of a sudden, you're not going to see
your abdominal muscles. You've eaten too much. Cut back.
Jonathan: I love it! No, that's just the new strategy now. You're on the
beach. I'm just going to go to the beach with a five-pound bag of
macadamia nuts and based on how people look I'm either going
to give them macadamia nuts or not based on their abdominals.
Dr. Sears: The reason why this is important is because fat is high octane
fuel. It really basically allows the elite athlete to perform at a
longer level because he has now basically—it's not how much
calories I eat. It's how many molecules of ATP I can make. You
can make a lot more ATP from fat than you can from
carbohydrates.
This is why you need a certain level of fat. Can you be too thin?
Of course, you can. But again, you're looking at the abdominal
muscles like the watch. It gives you a very, very good indicator if
you have adequate reserves to basically perform at high levels of
physical output.
Jonathan: Dr. Sears, some people perceive the Zone diet or the Zone way of
eating or even a SANE lifestyle like I advocate as a high-protein
diet because you're consuming more than the 50 gram
recommended daily allowance. Some people have even gone so
far as to say that eating a high-protein diet like this causes
cancer. Now I've publicly stated my opinion on this many times,
but I want to hear your thoughts.
entheos.com The Calorie Myth 9
Dr. Sears: Your thoughts and mine are one in the same. First of all, it's not
really a high-protein diet. Every nutritionist in the world will say,
"Never consume any more protein at a meal than you can fit on
the palm of your hand." Well, that's the Zone diet. Then if that's
too much protein, then every nutritionist in the world is wrong.
We need adequate levels of protein because without that we
cannot maintain our immune function. We cannot maintain
muscle mass or strength. Can you take in too much protein? Of
course, you can. Again, we follow that zone.
Now an elite athlete, because of their higher levels of exercise
and muscle mass will need more than the sedentary type 2
diabetic, but not that much more. In all of the Olympic athletes
I've worked with, none of them have ever consumed more than
2,500 calories per day because that's all they need to make the
ATP perform at high levels.
So again, saying it's a high-protein diet in terms of percentage of
the calories, yes. In terms of the absolute number of grams, no.
What is different is why the percentages of carbohydrates are
lower. You're eating a lot of vegetables. Any fool can eat pasta.
Any fool can eat bread, but eating two pounds of vegetables,
that's hard work. But that gives you basically adequate levels of
carbohydrates for brain function, but without overconsuming it.
You have a built in governor that says, "It's just hard to eat the
two pounds of vegetables per day."
Jonathan: Dr. Sears, we've all met people who eat and eat and eat and
don't gain weight. The people who get the most attention and
the people most common in this country are individuals who are
metabolically dysfunctioning. If they even smell a cupcake, they
gain two pounds. How is it—what is happening hormonally in the
gut, in the brain, wherever that causes the difference between
the individual who can literally drink weight gainer shakes and
not gain weight and the other individual who, if they eat one too
many macadamia nuts, ends up losing their six pack?
entheos.com The Calorie Myth 10
Dr. Sears: It's called genetics. Some of us are lucky and some of us are not.
I happen to fall in the category that's not very lucky. I have to
work very, very hard, because again, let's say what appears to be
a genetic defect in some ways, let's say 10,000 years ago, was a
genetic attribute. Those who could basically store incoming
calories more successfully as fat had a better likelihood of
surviving famine.
Today, basically the idea of famine is basically more than two
hours between meals. Again, our genes are working against us.
You have to base work and say, "It's not how much I weigh or
how I look in a swimsuit, but how well I am." My definition of
wellness is really how well are you controlling inflammation. That
becomes now the guideline. I don't care what you eat as long as
you're controlling inflammation. Inflammation is the reason we
get sick. It's the reason we age at a faster rate.
The Zone diet is really an anti-inflammatory diet. It's basically
looking at food from the perspective of endocrinology and
saying, "How can we now orchestrate these incoming nutrients
to have the greatest impact of reducing chronic inflammation in
our body?" That becomes really the telling card saying, "Is a diet
successful or not?"
By the blood samples that we and others have taken, Americans
are not very successful at controlling their levels of inflammation.
That's why our healthcare system is careening out of control. We
are basically more inflamed than any country on the face of the
earth and that's why our healthcare costs are really double the
cost. Unless we reverse this inflammation epidemic, our country
will be bankrupt in a few years. Make no mistake about it.
It's really basically saying, "Not what is the best diet for weight
loss." It's really, "What is the best diet for inflammation control?"
That will be a lifelong struggle. If you don't have the right
genetics to basically look great in a swimsuit, that's okay as long
as you're basically constantly monitoring your levels of
inflammation in your body. If you are and they're under control,
entheos.com The Calorie Myth 11
then you're going to live a good, long, and healthy life. That's
basically what nutrition is all about.
Jonathan: Dr. Sears, you mentioned really the focus is on inflammation not
so much on this conscious control of calories in, calories out as
we were led to believe over the past 40 years and the Zone diet,
as we've talked about here and as folks who have read your
obviously bestselling books know is about the manipulation of
the quality of food you're eating. We've been talking about the
quality of carbohydrates, the quality of fats, the quality of
protein. You have not once said, "I want you to count the number
of calories you are taking in."
Is the chain of events that happens here in the Zone diet model
and the physiological, endocrinological model you've established
something like this? Individuals eat the wrong quality of food.
That causes inflammation and inflammation causes the body to
become dysregulated, which makes us then overconsume and
under expend energy because the body is broken down, for lack
of better terms, which then results in obesity and disease. Is
that—because right now we just hear we just eat too much and
we get fat and diabetic. That seems like that's not fitting within
the model you're describing.
Dr. Sears: No, you're quite right. It basically is about the inflammation and
your ability to control it, because the inflammation, if you
consume too many calories, it basically causes disruption in our
signaling systems. We have really three primary signaling
systems that have to work in concert. One is in the blood. That is
the hormones in the blood. Another one is the brain and how it
innervates those incoming messages, and the third is in our gut.
In terms of the gut, in terms of basically releasing hormonal
signals, but our other hundred trillion friends called bacteria,
who are a major part of our GI system.
This is why we understand why gastric bypass surgery works
now. When you talk to the gastric bypass surgery patient when
they wake up out of surgery, the first thing they say is they say,
"My God! I'm free. I'm free at last!" You say, "Oh, free of what?"
entheos.com The Calorie Myth 12
"Free of hunger." Because they're no longer hungry because the
re-routing of the intestine has now dropped the limited amount
of protein in the deeper part of the intestine to release
hormones that go directly to the brain that say, "Stop eating."
We have these intricate hormonal control systems that tell us
when we're hungry and when we're not hungry. What we find is
changes in our diet that basically cause those control systems, as
elegant as they are, to become discombuberated. As a
consequence, we have lost the ability to control satiety. Satiety is
simply the lack of hunger, but it has a very, very precise
hormonal and endocrinology description of what has to have
happen.
I think that the more we understand really the intricacy of
basically hunger, why we gain weight, all these old aspects, eat
less, exercise more fall by the wayside. Don't you think that the
overweight diabetic says, "Wow! I never thought about this, 'If I
eat less and exercise more and I'd lose weight.'" Well, what
happens when people tend to eat less and exercise more? They
get tired and they become hungry. How long do you want to go
through life being tired and hungry? Not very long.
What you're looking for is a diet that you're never tired and
you're never hungry. You'd say, "Well, that's a diet I can live with."
It's like, "Exactly!" That's a root word of diet. It comes from the
ancient Greek, which means "way of life." You're looking for a
way of life that basically you make some adjustments as you go
through life, as you age, yes, you'll have some adjustments there,
but that you go through life never being hungry, never being
tired.
Jonathan: Dr. Sears, when an individual looks at the primary research,
when they look at the work of people such as yourself, this
makes not only so much common sense, but it is so backed up in
the research and also if you just understand you can study this
pharmacology. It's not controversial. When you eat sugar, insulin
does this. There's no need to debate. It can be demonstrated
and proven.
entheos.com The Calorie Myth 13
This idea that the body seeks out health and seeks out balance,
again, that seems to be understood. If you look on Wikipedia and
you look up blood sugar, it uses the word homeostasis. It says if
the body's blood sugar rises, the body tries to bring it down, and
if it goes down, the body tries to bring it up. Why do we just
continue to hear the message of gluttony and sloth rather than
the breakdown of the body's ability to balance energy
automatically, just like it balances blood sugar, blood pressure,
everything else?
Dr. Sears: Because we want to ignore the facts. There are three things in
life which are very visceral. Religion, politics, and nutrition. Once
you believe, you say, "Don't confuse me with the facts because in
my heart I know I'm right." What we've had in the last 40 years
has been a political discussion and basically the science has been
the casualty of that political discussion.
Let's even look at the aspect of carbohydrates make you fat. Not
necessarily if you have a good regulatory system. Now
carbohydrates will make you fat if you have them combined with
insulin resistance caused by inflammation, which maintains high
levels of insulin all the time. That's going to make you fat.
Jonathan: Yep.
Dr. Sears: That's why I say this elite athlete, he eats eight pounds of pasta a
day. He's not fat. Well, because he's basically counterbalancing
that with the exercise, but the day he stops exercising, those
eight pounds of pasta will make him fat because he'll start
basically adding more Omega-6 to his pasta and so it's not as
simple that carbohydrates make you fat. It's inflammation that
causes insulin resistance that makes you fat.
But these are more complicated arguments that the American
public wants sound bites. They want to basically live and die by
Dr. Oz. Therefore, if they know better, tend to basically dumb
down their arguments so they lose the scientific validity. Or they
have no idea what the arguments are in the first place so they
entheos.com The Calorie Myth 14
can't dumb them down. They find something that basically is
really kind of out there that they can stake their hat on.
There's nothing more complex in existence, not only for humans,
but for every species than basically the diet. It basically is the
reason why we exist and we always are seeking for the optimal
aspects to maximize our resources. I think the time will come
hopefully—hopefully in my lifetime when we bring back the role
of diet in terms of logical, scientific aspect. It doesn't have to be
complicated to you. I said if you've got one hand, one eye, and
one watch you can do it.
Now what's happening in your body is incredibly complex. To
ignore that is to basically give more rise to greater confusion of
Americans and they're totally confused right now as what to eat.
Jonathan: Dr. Sears, I admire your persistence because you've been beating
this hormonal drum. It's a fact of life that we're going to continue
to live in a world of sound bites. I mean I feel like the Internet,
things like that are helping because we now see people that
know more, well more about nutrition and hormones and gut
health than their physicians because they have the Internet now,
but you've been beating this hormonal drum for many decades.
It does seem, if we need a simple answer, right now that simple
answer is calories. Just calories in, calories out, count them, eat
100-calorie snack packs, weigh your food, yada, yada, yada. But
what you say and what so many other people say and what the
research says is think of food and exercise as a control system
for your hormones. That seems as simple. Instead of calories,
think about hormones. How can we continue to make that shift
in our culture?
Dr. Sears: Well, unfortunately the answer is education. Right now, we don't
have education nutrition. We have screaming matches. Until we
get back to where we try to address this like civilized humans,
we're going to have this constant shouting match from one side
to the other.
entheos.com The Calorie Myth 15
But for the average person, say, "Yeah, basically use your body as
a data point of one." Make some experiments. Try balancing your
plate better. Do you feel better? How long does it take? Harvard
has told us. It takes one meal. One meal, you're going to find out.
Just keep adjusting until you say, "I've got it."
Then basically here's the hardest part. It's called execution. Then
you say, "I've got it scientifically, but now I've got to execute it."
That's the hard part. The science part, I get it. But it takes usually
a year, if not longer, to change habits.
Jonathan: Gotcha.
Dr. Sears: That's the hardest part. People basically say, "I want an
instantaneous format." Not going to happen, but you have the
rest of your life to be working on it and give yourself a year so
you can find out within the first day something is different.
Jonathan: And you can have the confidence of knowing maybe on two
fronts, one, it's not as if what we've been doing is working, so
you're not risking very much, right? The path we're on seems to
be going pretty poorly and the pot of gold at the end of this
pursuit, as you've said, it's not a diet. Maybe it's better
characterized as nutritional serenity when you just eat and you
don't have to think about how much you're eating or when
you're eating, you just do it and you've got your hand, your
watch, and your eyeball and you're healthy and you're happy.
That's a pretty awesome state that very few of us are
experiencing right now.
Dr. Sears: Well, yes. I'll go back to emphasize that. Yeah, healthy and happy.
It's a rarity in America. You're looking at a little experimentation,
but here's a good rule of thumb. If something doesn't make
commonsense, then it's probably nutritional nonsense. When
you start this, you're looking for these wild explanations. Stand
back and say, "That's nonsense."
Now it does take work. There's no question about it, but the
question is is your future worth it? I think it is. Call me crazy.
entheos.com The Calorie Myth 16
Jonathan: Dr. Sears, it's such an empowering message, though, because
right now what I hear you saying is it's simple. It might not be
easy to execute, but it is simple. That makes sense to me
because no one knew what a calorie was. We didn't understand
all of this science even 100 years ago, and people were still
slimmer and healthier back then. I don't think we've all gotten
lazier and dumber, so it must just be that if we get back to that
simplicity that we had, which was just eat things you find in
nature and that's one actual followup question, Dr. Sears, is we
talked about the colorful carbohydrates, the high-quality protein.
Certainly some things you find in nature, like a potato for
example, is not a colorful carbohydrate. It is found directly in
nature. It was part of the diet of humanity for many thousands of
years. How does that fit within this model?
Dr. Sears: Well, I go back to saying if it's not white, don't eat it. It's as simple
as that. We have to, again, treat this like a political campaign. You
make it simple for people to say, "The more white you put on
your plate, the more inflammation you're going to create." It's
saying, "Do you feel lucky? Do you feel lucky eating that potato or
that piece of white bread or that piece of white pasta or that
serving of white rice?"
You might be. Who knows? But I know most people are not. But
it's been around saying, "Well, strychnine has been around for a
long time. That doesn't make it healthy." It's saying you use your
eye to put the least amount of white on your plate and the most
color, try to balance it the best you can, and look at your watch
and say it's a game. Treat it as a game, not as some type of
arduous task. This is not like Hercules washing out the stables,
but it's a game. What's the end response? A longer and better
life. Once you learn how to master the game, then the goal
remains in sight.
Now the trouble is you're not going to really find out how that
happens until you're really about age 60. Up to age 60, you can
eat virtually everything and probably get away with it, but as you
entheos.com The Calorie Myth 17
get toward the last quarter of your life, things start catching up.
You say, "That's my long-term retirement goal is to basically live a
healthy and happy life."
This is why, again, I go back to the happiness. There's a very, very
strong connection between our diet and our ability to be happy,
because basically we're looking for—happiness can be defined
many ways as the levels of dopamine in your brain. The more
dopamine you can produce, the happier you are. That's why we
run around doing things sometimes really dumb that increase
dopamine levels. "I'm going to take this drug, drink this alcohol,
do this." But it turns out diet is a very powerful way of
maintaining constant levels of dopamine in the brain. If the
dopamine in the brain is constant, you're happy all the time.
Jonathan: That's very promising because often we hear that, "Well, if I can't
eat these refined carbohydrates or processed fats, that's what
gives me enjoyment in life." It sounds like what you're saying is
we can prove clinically that if you can quantify enjoyment, it's the
level of dopamine in your brain and having proper nutrition, the
area under the how much dopamine you have curve will be
higher than if you had these teeny tiny little spikes from
processed garbage.
Dr. Sears: Unfortunately, the teeny tiny spikes give rise to a very rapid
depression. You get, "Yes, I feel great eating my Dunkin Donut,"
then about an hour later it's like, "I don't feel so good." Basically
now the area under the curve is zero. The good spike has been
knocked out by saying, "I feel miserable."
You want to basically say, "If that's a goal," say, "I've now got a
biochemical measure. It's not how good I look in a swimsuit." It's
like, "How much can I maintain happiness using my food as my
ultimate drug?" You can talk about this because you can look at
diseases like depression and other diseases like, let's say,
attention deficit hyperactivity disorder. Both of these are
characterized by decreases in dopamine, along with serotonin.
The only agent known to man that can increase both serotonin
and dopamine is called fish oils.
entheos.com The Calorie Myth 18
The more fish oil you can put in your diet, the happier you're
going to be. The happier you're going to be, the more likely
you're going to make the right choices and like that frontal cortex
say, "Hey, that's a dumb idea. Don't do it." But if you don't have
basically a good-functioning brain, basically that limiting system
is going to take hold and you're in trouble. It's like saying,
"Dopamine made me do it."
Jonathan: I love it. What do you feel is—just to wrap up here, Dr. Sears? I
mean there's been so much advancement over the past 40 years,
right? We started in 1977 down this path where the Senate Select
Committee said, "Just eat less, exercise more." We are where we
are today where we're talking about inflammation and we're
talking about homeostasis and we're talking about hormones.
What do you see as the next big field to be explored in the
modern science of nutrition and exercise?
Dr. Sears: Well, I think it'll be building a bridge between these two ruling
factors which are pushing against each other. One: We're
running out of time. I don't have time to make the right choices
even if I knew what they were. Two: I have a better idea what the
right choices are, but basically life gets in the way.
I think that I really feel we're coming to another age of what I call
processed foods 2.0. Processed foods 1.0 have been the foods
that have gotten us into trouble. They're convenient. They're
tasty. They activate the dopamine receptors, but they're not very
good for us.
I think the real challenge, because time will still be compressed,
even more so as time goes on. We're not going to go back to the
old days. We may have to be looking at, I think, thinking out of
the box approach, of thinking of processed foods 2.0, that have
to be convenient, they have to be tasty, but now they have to be
able to increase dopamine and stop hunger. If we achieve that,
we may be able to get our way out of this problem. Processed
foods got us into this problem and I think the processed foods
may have the opportunity to get us out of the problem because
entheos.com The Calorie Myth 19
most people the most precious commodity of time is being
compressed so much that the time to make foods, buy foods,
and eat foods is disappearing.
I think we have to basically start things from a really out-of-the-
box approaches because even though we have the best
intentions, life gets in the way.
Jonathan: You said out-of-the-box approaches. It sounds like one of those
out-of-the-box approaches might be finding a way to put things
into the box without making them toxic for us.
Dr. Sears: Exactly. It's a challenge, but I think basically science thrives on
challenges. If we want to basically take the next step and say,
"Okay, as we understand more, can we make now foods that
basically can be not as a replacement, but be as a partner? A
partner for the times you can eat the two pounds of vegetables."
It's hard work. I try to eat two pounds of vegetables a day. It's
hard work! Is it worth it? Yes, it is.
But again, we have to have basically adjuncts to basically bring it
to play because the bottom line, we are in a totally unsustainable
situation globally. The one disease that will destroy every
developed country in the world is type 2 diabetes. That's bad
enough, except that we know that type 2 diabetes, you're two to
four times more likely to develop Alzheimer's disease.
We've had an epidemic rise of type 2 diabetes worldwide, which
means 10 to 15 years from now we'll start to see another
epidemic rise of Alzheimer's. That's the end of healthcare as we
know it worldwide. We have a clock that's running out.
Until we basically focus our attention on some of these more, I
won't say esoteric, but taken out to say, it's not as simple as eat
less, exercise more. It's not so complex that you can't do it, but
we have to basically say—we have to have a commitment to say,
"You might need a hybrid system of both foods and processed
foods 2.0 so they can be working in concert to basically allow you
to retake control of your genetic future."
entheos.com The Calorie Myth 20
Jonathan: Dr. Sears, it's certainly also true that having a future where we're
all diabetic with dementia and obese, that's not easy either. We
say it might be a challenge or hard to eat this way, but it's also
pretty challenging to go through life sick and overweight. It's a bit
like we can pick which path we want to take. Sadly, nothing in life
is easy or free.
Dr. Sears: Agreed. That's why we go back to education. It's education,
education, education. Yet, we tend to basically—are becoming
less educated. That is we basically now are gravitating toward
political statements. As a consequence, we get further away from
our goal of saying, "What are we really doing to our bodies?" This
is just not a personal question because we now know through
epigenetics that there are trans generational effects and that the
sins of the mother and the father can be amplified and
transmitted to the next generations. Not just next generation,
but next generations.
We're in really, I think, in many ways, a fight for our genetic
future. It's being eroded before our very eyes. If we have an idea
for the future for the human species, we've got to get back on
target as quickly as possible, because as these epigenetic
changes induced by our diet become more constant, you run the
risk of having them become permanent. Then, at that point, it's
too late. I think we have a challenge, a very major challenge,
really we're not talking about losing weight, but we're really in
the survival mode for our species.
Jonathan: Listeners, as you take this incredibly powerful words to heart and
you hear this message of education, certainly Dr. Sears has been
a pioneer in educating us for decades now. If you haven't
checked out his work, I would highly recommend it. You've
certainly heard of the Zone diet. You can learn all about it at the
zonediet.com. It really is, to me, more of a framework. It will get
you to start seeing food as a control system for your hormones
rather than just a way to manipulate metabolic math, which
really doesn't add up anyway.

Dr. Sears, thank you for all that you've done for so long to help
educate on this lifesaving topic.
Dr. Sears: Thank you very much and hopefully opportunities like this will
basically hopefully get the message out.
Jonathan: Absolutely! Dr. Barry Sears, thank you so much!
Dr. Sears: Thank you.
Jonathan: Bye-bye.
