Video Summary
AI GeneratedThis video explains that individuals have unique metabolic types (A, B, or C) that influence food cravings, personality, and health. By tailoring the intake of proteins, fats, and carbohydrates to match their specific type, people can optimize their energy levels, reduce anxiety, and improve overall physical and emotional well-being.
Now science has discovered that just like there's a blood type or a body type,
every one of us is born with a unique metabolic type. The same foods that keep
your friends slim, they make you puffy and tired. So you got to eat right for
your type. So what is your metabolism type? Well, you can't tell it just by
looking at the outside of somebody. Sarah, Jen, and Emily are joining me. If you
don't mind, you could all stand. So just by looking at your body types, you'd all
think you'd burn calories sort of the same way, wouldn't you? In fact, you're
sisters. Yes. Thinking about your dad, what he went through. So just because you
look the same on the outside, the metabolisms can be quite different. And Kate, in
fact, yours are. So today we're going to help you find yours. I'm going to go
through the main characteristics for every metabolism type. Let's start with
the first type. Have a seat if you don't mind. We'll talk about Sarah. You go first.
Okay. So let's talk about the foods that you crave. Okay. Well, I'm obsessed with
potato chips and pretzels, and I love salt. So salty snacks. Yes. Potato chips and
pretzels in particular. What kinds of things... Actually, I'll ask differently. Do you find
yourself to be sort of a calm person, or are you more anxious? I could ask your
sisters if you want. They'll answer, yes. I'm easygoing, but I tend to get a lot of
anxiety, and I don't know why. And what do you do when you get anxious? I eat an
entire bag of potato chips, but they're baked. I go for the baked ones. So this is
an important point. It may be that your reaction to the stress, anxiety that
you're feeling, which is to get those potato chips which have salt on them, may
actually be causing the problem that you have, which is pretty typical for a lot
of folks because your metabolism doesn't process those foods as efficiently as it
should, and your body is crazily trying to get out of this vicious cycle
that you created for it. Because you are, in fact, metabolic body type A. You're not
alone. It may be happening to a lot of other women who are craving salt just like you.
And here's what metabolic body type A is all about. It's about people who have a
strong appetite. They crave fatty, salty foods. Let me know if this checks out
with you. They often feel fatigue and anxiety. They are talkative, and they're
outgoing. Is that you? Yes. Sister's nodding yes. All right. How many of you think that
you're type A? Put your hands up there. There's a fair number of people. So I don't
want you all to worry. I've got a plan for you. In fact, I've got a plan for
every one of these metabolic types, but we want to identify which one we're all
in for. So we're going to put you in type A. Okay. Let's shift to the next type. Jen,
you have a very different reaction to food, I understand, than Sarah does. So
what's the classic go-to snack for you? I have to have my ice cream. Ice cream and
sweets. I love it. It's like my oxygen. If I don't have ice cream, I'm in
trouble. And does your body react well to that? Does it energize you? I don't know
about if it energizes me, but I just love it. So here's the deal. You know, a lot of
folks react very differently to salty foods versus sweet foods. This is one of
the big differences between these two different types. So in the middle of the
afternoon, Jen, when you're feeling a little bit tired, what do you do? So I try to
focus throughout the day, but yes, I do get tired, and I have to have, I crave
also coffee. I have to have a latte in the afternoon. It focuses me. So caffeine
to focus you, and you like sweets. So you are classic metabolism type B.
Let's define what that means for everyone at home as well. These are the
characteristics. Remember these. Relatively weak appetites, not quite as
much as your sister. Ambitious, craves sweets, you're organized, you tend to get
stressed out, and by the way, that makes you very dependent on caffeine to rev
you up a little bit more because you sort of peter out otherwise, and you
tend to be sensitive. That's true. That true? Yes, she's very sensitive. I like
that. There's agreement here. Now listen, I'm gonna be clear about this. This is
different from anything we've ever spoken about on this show before
everybody. What I'm trying to say is the foods that you're eating are directly
affecting your personality, and your personality, the cravings you have are
actually taking you into the foods that create that cycle that we spoke about
earlier. So it's an important observation. All right, now if you're
having trouble figuring out if you're type A or type B, which I suspect a lot
of folks are, well then you may actually like both salty and sweet. You may
actually be a combination. You might be like Emily, who's actually metabolic type
C. Right, I love it all. I love chocolate covered popcorn. My favorite snack is a chocolate
covered popcorn. Are you kidding me? That is truly a combination. So you like both
types of tastes. You have a sort of combination of personalities. Are you
generally more calm or anxious? I try to stay calm, but I worry a lot and I'm very
nervous. And I worry when I don't even need to worry. So that's just how I act
normally. Agreed sisters? Yes. But you don't have to worry anymore because it
might be the foods that are actually causing you to behave that way. And this
is one of the reasons I feel so passionate about this topic. Because if
you could clue in to how your metabolic body type, the desire of your body to
eat certain foods is affecting your personality, you can adapt accordingly.
So here are the classic characteristics of type C metabolism. Fluctuating,
unpredictable appetite. It could be a combination of sweets and salties like
you like with the chocolate covered popcorn. I can't believe you like those
by the way. Tend towards anxiety and nervousness. And a lot of times folks
will suffer lots of aches and pains if they're a metabolic type C. Well I do have
back pain. You do? She complains about it. She complains about it. Well the
complaining element is a big part of it by the way. And that goes with C a fair
amount. One of these is not better than the others. These are just an observation.
And he's always the best. People will vary and whatever they are, they are. There's a ton
of science that's been done over the last half a century looking at this
basic foundation of work. And it comes back down to insights about how we're
all different because we came from different places. Let's start with
everyone like Sarah who craves salty foods and suffers from a little bit of
anxiety and treats the anxiety with more salty foods. That's called the metabolism
type A. That's what you are now that you know that. Yes. And everyone at home again you
can take the doctorize.com quiz and figure out exactly which metabolism type
is. Your metabolism very efficiently utilizes proteins and fats. That's true
for all type A's. And so because of that you actually prefer to use those more
than carbs in your diet. You're craving salt because it's actually reminding you
about meats and about proteins and things like that. So your plate ought to be 50
percent protein, 30 percent fats, and 20 percent carbohydrates. Is that clear? Yes.
And literally this is what your plate ought to look like. So there's no chips on it.
No chips on this. Again you want the salt but not in the form of carbohydrates. It
should be the least common thing in metabolism type A people's diets because
it'll take you in the wrong direction and cause that anxiety that you're
having. That's especially important for type A's to recognize you have to have a
little bit of protein in almost everything you eat. At least get you in
the right direction. But it's not just any protein. If you notice I picked
darker cuts of meat. So steaks obviously but darker types of poultry, dark
colored fish like tuna and salmon. You sort of want that kind of darkness in
your life because your metabolism is geared up to eat this and digest this
kind of food. Usually I do white meat. No, no, no. White meat we're going to get to over there.
Your sister's got that. You may go in that direction but it's actually not
what your metabolism is telling you to do. The other thing that's sort of
interesting if you just look here. I put some some dairy here. If I were to open
your fridge right now, what kind of percentage fat would I find in the dairy
products you have? It would be skim milk and fat free or low-fat cheese. You are
done that. From now on I want you, and this is good news, you may have some fat in
your dairy. So I can eat real cheese? Yes, real cheese and you can have 2% fat
milk. I actually think it's better for your metabolism type because people make
the mistake of believing that by having a low-fat dairy product they're better
off. That's mostly sugar, which puts you over here in the carbohydrate
category. You want to try to stay over here as much as you can. Fair enough? Yes.
Remember metabolism type A, just a little bit of refined and starchy
food. You can't have very much because you can't metabolize it effectively.
You're in? Yes. Okay. What don't you like about it? How can I help you
understand it better? The dark meat scares me a little bit. I've always been
told to eat white meat. You know that's a fallacy. There's not a big health benefit
just abstractly between dark meat and light meat. I don't know why that got so
prevalently believed in our society, but it's not the case. In fact, if you like
the taste of one over the other, you'll probably ought to go in that direction.
But once you know your metabolism type, you know where to stay. Okay. Now this is
one that Jen, everyone else like Jen who craves sweet foods, the
metabolic type B people, they have to adjust their metabolism a little bit by
realizing they will easily store carbohydrates. That's why your body likes
sweet things. It actually will desire to be on carbohydrates. It just doesn't want
candy. It wants real carbohydrates. So I put here 70% of your plate being
full of carbs. You get about 20% or so of proteins and only 10% of fats.
So it's very different from what we just left Sarah with. I like to eat her diet though.
You do, don't you? I mean this bread is scary. But you know the thing is, if you don't
eat the diet that's designed for your metabolic type, then you're gonna end up
craving that caffeine all afternoon. You're gonna not be able to function the
way your body naturally wants to function. It can't deal with the slower
processing of some foods over here. You know, you actually get through this
food in different ways. You've got to have it as the main part of your diet.
Okay, well that's exciting because I love bread, but I just don't eat it.
Well now you can have a little more bread, but it's gonna be 100% whole grain bread.
Same, these are all healthy carbohydrates. I recommend you go out
and get sugary stuff. Fair enough? Now the one thing that, you know, type B's
really do great on a low-fat diet, relatively speaking. So try to slice it
down as little as you can in your diet, and this will take you to the right
place, generally speaking. What's your favorite thing on here?
I would have to say the fish. The fish. Well the fish can go, but you know, notice it's
light fish. Light meat. This is breast from poultry. Right, and it's funny because I
like dark meat. You do? No wonder! You must have driven your father crazy.
Your dairy also has to be low-fat dairy, because you can't get away with the fat
that Sarah can get through. Okay, that's what type B's do. All right, finally, unlike
type A and type B, we've got, for Emily and type C, a whole different program. This is
for people who crave both salty and sweet food, like chocolate-covered
popcorn. You're neither type A nor type B like your sisters. You're type C. If you,
like Emily here, are often suffering aches and pains, and you're often also in
metabolism type C. You've got your back pain, and you crave sweets and salts, so
what you need to be eating for your diet is very different from what type A and
type B's can tolerate, even if you look the same, and even if you're related to
them, because type C folks have the ability to utilize all three nutrients.
Fats, carbs, proteins. You can do all three equally, and so we divide your plate into
30%, you know, a third each of those major groups of fats, of protein, and of
carbohydrates. Interestingly, that means you actually get to have more fats than
either of your sisters over there. That's good news for most people. You're
gonna celebrate about that? Which of these fats do you like the most? The eggs, and I typically stay
away from cheese, but it looks like I should be eating more of it. You can
have more of it, because your metabolism will deal with it in an effective way. It
also pursues some of the other issues you have in your life. Again, I'm gonna be
clear about this. What's different about this idea, and it's been looked at for a
long time, is not just that you have metabolism differences, but that the
foods you eat change your personality, and so take you in a place you don't
want to be. So if you want to avoid having the aches and pains, and be
concerned about them, and complaining about them, and dealing with them in that
way, this is a diet that will take you in that direction. You also, by the way,
notice it's a mixture of different colors of proteins. So you'll have the
light and the dark colored fish. You can have light meat and dark meat poultry.
You can have beans and steak. You can have anything you want, which is a little
different from what type A's and type B's can tolerate. And finally, you can
fill up the last part of your plate with carbohydrates, because you're free to
have those as well. So again, I want the healthier versions of all these. So let
me go through this again. And by the way, this is, I gather, you pointed out the
dairy's a little different. Are there other differences between your normal
plate and what we're having here? Actually, it looks pretty similar. Good. So
we're heading in the right direction. All right. Let's look one more time at all
these three plate types, because I want you to all remember these in case you're
at type A, for example. Sarah's over there celebrating about her type A plate,
where it's half meat, mostly dark colored, and then the breakdown of fats and
carbohydrates. What do you like the most about your plate? The cheese. You like the
cheese. Well, you're allowed to have 30 percent fats. That's pretty good. I want
some of her plate, though. You want some? Of course. You're sisters. Of course you
do. All right. And Jen, you're type B. And you know, type B folks, you have sweet
tooth, but they're allowed to have lots of carbohydrates. The right kind, of
course. What's gonna be the hardest part about being on this program? Like
thinking that I can actually eat bread and cereals, which I've really cut for my
diet in the last 10 years, basically. Because you thought it wasn't good for
you. Right. I would argue that you should eat them both because in the long term, I
think it'll actually support your diet, but it'll also help other issues that you
may want to deal with in your personality. You probably get off the
caffeine. Okay. And finally, let's talk about, Emily, your balanced approach.
What's gonna be the biggest challenge about this? Just doing the 30 percent of
because I tend to stay with the proteins and with the grains and potatoes. What I'm
looking forward to is your family meals. I'm gonna come over at Thanksgiving, see
what's going on. You're invited. Thank you for watching. Don't forget to subscribe
