Fat Adaptation VS. Ketosis | #ScienceSaturday

Fat Adaptation VS. Ketosis | #ScienceSaturday

– What’s up, Jigsaw land. It’s Thomas DeLauer, and lots of people have
been asking questions about fat adaptation. Questions about ketosis, on the difference between when your body uses fats for fuel and when
your body wants to use carbs. So I wanted to clear some stuff up. Make it known that you don’t have to be keto to be fat adaptive, but you might need a
little keto to get there. So let’s talk about the science. So what is fat adaptation,
and what is ketosis? Ketosis is where we are producing a certain amount of ketone bodies. By definition, ketosis is where we are
producing between 0.5 to five to six millimoles
per decaliter of ketones. We’re talking about acetoacetate,
beta-hydroxybutyrate, and acetone, the three main ketone bodies. That, by definition, is what ketosis is. But it doesn’t necessarily
constitute being fat adapted, where your body uses fat, or
ketones, as a source of fuel. Like I said before, ketosis
is just a means to get there. What you’re doing in a state of ketosis, is you’re nutritionally
providing enough fats so that your body has the
stimuli to produce ketones, thereby making you fat adapted for that particular point in time. You see, fat adaptation is where your body is actually accustomed to
utilizing these ketones. It means it starts to change the body, the dynamic of the cells,
so the body can use these. Let me give you a personal example. There was a period in my life where I was in a
nutritional state of ketosis for about two years straight. Now I’m convinced that doing that, being in ketosis for that
long of a period of time, got my body so fat adapted that nowadays, even if I’m not in ketosis, my body still wants to utilize
fats as a source of fuel. I have become what I
would consider sort of permanently keto-adapted, or fat adapted. In this video I really wanna
show you how to get there, but you have to have an
understanding of how it works. You see, maybe you’ve heard
of the keto flu before. The keto flu is an interesting thing, because all the keto flu
is, is where your body is so used to utilizing
glucose and glycogen, the carbohydrates that we store in our muscles as a source of fuel, that it kinda freaks out when we have a massive influx of ketones. It just hasn’t gotten to the point where it knows how to utilize them yet. You see, we haven’t developed the enzymes to really break down those
ketones or those fats very well just yet. We haven’t developed the
mitochondrial machinery to truly utilize those ketones the way that we need to within the cell. But it takes a little
bit of time to get there, but when it does, it’s awesome. You see, that’s why the keto flu occurs. Because you’re kind of in that gray area where your body’s just
not quite there yet. But once you’re there,
things start to happen. The cells say, “Wait a
minute, I can use these.” Let me give you another example. If you’ve been in ketosis before, and you’ve ever used
those little keto sticks, the ones that you pee on, they turn a certain color
if you’re in ketosis, you may have found that in
the first couple of weeks of ketosis, you showed a
large level of ketones. You showed that you were in deep, deep ketosis on the keto strips. Then maybe three, four, five weeks later, you weren’t really showing any ketones, and you started freaking out, thinking that you weren’t
in ketosis anymore. Well how that works is those ketone strips are measuring excess ketones
that you’re excreting. They’re not measuring the
ketones that you’re using. So that’s why, for the first few weeks, you excrete a lot of ketones, because your body isn’t
efficient at utilizing them yet. Make some sense? So just because the ketones
drop off on that strip, doesn’t mean that you’re not
in ketosis, or not fat adapted, it just means that your body
is actually utilizing them, and you’re not excreting the excess ones. So it’s really, really intriguing. Now the thing is, studies
are starting to show that you can remain fat adapted even when you’re not in ketosis. So like I’ve said before,
ketosis can be a tool for six to eight, ten weeks
of being consistently in keto, to get your body optimized to using those fats as a source of fuel. Even Dr. Dom D’Agostino in the
University of South Florida was talking about how people
that have been in ketosis for a long period of time can usually get into ketosis much faster the second, third, fourth, et cetera,
et cetera time around. They can just pop right back into keto ’cause their body already has
the mitochondrial machinery and the cellular efficiency
to utilize those ketones. So that’s really cool stuff. That means even if you
start consuming carbs and you come out of keto, your
body still wants to use fats. So the second that you’re
in a caloric deficit, your body prefers to
start using your body fat rather than breaking
down your muscle tissue. And to make some total sense of this, I wanna reference a study. And this study is going to
sound very, very familiar to some of the things that
you’ve probably heard before, and definitely familiar
to some of the things that I’ve heard as a nutritional coach. I’m gonna start with what the concern is. People always think that
if they go into ketosis, they’re gonna lose a bunch of muscle. They’re gonna lose lean tissue, and this study proves that you do, but only in the beginning. Alright, here it goes. This study was published
in a journal called Metabolism: Clinical & Experimental. And what they did is they
took a look at test subjects that were on a keto diet
that was low calorie, and a non-keto diet that was low calorie. Both diets had the same amount of protein. Well, three weeks into the diet, they found that those
that were on the keto diet had a small decrease in
their lean muscle mass. Yep, alarming, right? Scary. Don’t do keto! This is the point where
most people will freak out, and they’ll say, “Ah, I’m
gonna lose all my muscle, I’m two to three weeks into this diet, and I feel like I’m losing size.” But guess what they found? After three weeks, the
differences totally stopped. Meaning after that, after three weeks, whether you were in keto or not in keto, the amount of muscle lost or
retained was the exact same. What does that tell us? That tells us that at that point, our bodies had become fat adapted, and started utilizing
fat and no longer had to start sacrificing muscle
to turn into glucose for fuel. So it goes to show that yes,
when you first start keto, you might lose a tiny, tiny bit of muscle as a sacrifice for a lifetime of fatty acid
utilization in the body. A small price to pay to
know that you have now turned on a cellular mechanism
for your body to utilize fat. You’ve turned on a cellular mechanism for your mitochondria
to leverage fatty acids as a source of fuel. You have now become fat adapted. It’s a small price to pay. It’s like a small investment in your body to turn on and activate
a part of your body that you didn’t even know you had. That’s the difference between
fat adaptation and keto. So don’t get them confused. Keto is required to get there, but it’s not required to maintain it. Now, let me say this again. Keto is awesome, and
it’s an amazing lifestyle that you can live life, and
live very, very happily with. I’m just saying that fat
adaptation is different from keto. I love keto. It’s a lifestyle for
me, it’s something that I’ll continue to live
just because it’s great, and it’s sustainable, and the health benefits
are totally awesome. But that’s just me. And just so that you all know if you are on a low carbohydrate
diet, or a ketogenic diet, you’re probably deficient in the minerals that you need to feel your best, so make sure you click on the link and check out some
Magnesium SRT from Jigsaw, so that you can get your
hands on the best stuff to help you feel your best
when you’re going through keto, low carb, or just good old life. I’ll see you there. (calm techno music) (xylophone tones)
