The mathematics of weight loss. What’s
the real deal with calories? I’m gonna explain it so you get it once and for
all. Hey I’m Dr. Ekberg with Wellness For
Life and if you like to truly master health by understanding how the body

so that you don’t miss anything. So I saw a very interesting video it was a very
geeky and illustrating video I love that sort of stuff it was by Reuben mere man
is called the mathematics of weight loss and he was asking a question and he said
when you lose weight where does it actually go and none of the people that
he asked knew that of course because they hadn’t read physiology if you have
read physiology you know that fat is stored in long chains of carbon and
hydrogen and oxygen and when you breathe in and you convert you metabolize under
the use of oxygen with the use of oxygen you turn that carbon and those
components into carbon dioxide and water so basically all that fat that you’re
burning you breathe it out as carbon dioxide and water and you can’t see it
so you don’t know that it’s happening but that’s how it works so then he
admitted to being a physicist which he was a great one it was very entertaining
but he admitted to not being an expert on weight loss and not knowing much
about health but he went on to say that what worked for him was to eat less and
exercise more so his conclusion was that all you have to do to lose weight is eat
less move more and keep breathing so while that is good advice biology
doesn’t work quite like that because physics and chemistry have a set of
rules they’re very very rigid that very precise and they work in a physics lab
and in a chemistry test tube but biology is different biology is governed
by on the rule so while biology is combination of biochemistry and
physiology the biochemistry asked answers what happens how did the
molecules combine but physiology asks and answers why why does this happen and
the big reason is that we live in an environment biology human living beings
we interact with our environment for the purpose of survival and under the
influence of hormones so let’s talk about that and let’s talk about how
calories really work so let’s say that the average person just for simplicity
burns a hundred calories an hour and you learn a little more here and a little
less there but just average it out and keep it simple what we have to know is
that your body can store a certain amount of carbohydrate as glycogen but
it’s very limited for most people is somewhere around 1,500 calories and
that’s represented by this skinny little rectangle here on the other hand your
body can store unlimited amounts of fat so an obese person might have 500
thousand calories stored as fat and a relatively thin person like myself is
still gonna have about a hundred thousand calories stored as fat so we
have a lot of potential for fat storage but we don’t have a whole lot of room
for carbohydrate storage so what we all want to understand here is that fat is
made up of carbon hydrogen and oxygen which ironically is the exact same thing
that makes up carbohydrate so these things are interchangeable they can go
from one to the other so when the body starts storing carbohydrate and it runs
out of room it turns the rest of the carbohydrate into fat of which you have
an unlimited amount of storage so let’s look at the
life in the day of a carbohydrate eater what does it look like so let’s say
you’ve filled up your carbohydrate stores before you went to bed and
through the night you burned 800 calories and half of that
was fat and half of that was carbohydrate just for simplicity that
means in the morning your carbohydrate stores have burned up 400 calories that
means they have room for 400 calories of carbohydrate so you wake up at 8:00 in
the morning and you have a cup of coffee and you have a slice of toast with some
jam on it and you have some milk with cereal and it doesn’t really matter
which cereal because they’re all grain they’re all carbohydrate whether you
call it corn or rice or sugar or granola it’s all carbohydrate so with that
breakfast let’s say it’s 600 calories your blood sugar is gonna rise very very
quickly and your body doesn’t like that it likes blood sugar in a very narrow
range it likes to have between eighty to a hundred and twenty milligrams of blood
sugar floating around that means you have about 1 teaspoon of blood sugar
floating around at any given time so that’s all one teaspoon you burn a
little bit you replenish a little bit you burn a little bit to replenish a
little bit with emphasis on a little bit and this is not a little bit this is an
enormous amount it’s a threat it’s an emergency
it’s toxic to the brain diabetics go unconscious they get into a coma when
the blood sugar gets too high so with that kind of breakfast and use some
insulin resistance your blood sugar might get up into the two three four
hundred range and now because your body your brain wants to live it tells the
body to make a lot of insulin what is insulin do insulin takes the sugar out
of the bloodstream and into the cell and because you only had room for so much
carbohydrate you quickly fill up the stores the excess get turns into fat and by
that mechanism insulin is a fat storing hormone so it’s not about how many
calories you eat or how many you burn it’s how do the hormones regulate it and
how do the hormones regulate your behavior because if the food you eat
triggers insulin that makes it fat storing that’s why a hundred calories of
fat is not the same as a hundred calories of carbohydrate because when
you eat it it influences hormones differently now insulin gets really
really high because blood sugar is really hot you gotta get it out of there
fast so blood sugar starts dropping and it drops fast because there’s a lot of
insulin and because it drops so quickly it tends to overshoot and now we have
what’s called reactive hypoglycemia and when you’re hypoglycemic what happens is
your brain doesn’t have enough blood sugar and now it says I gotta have some
you get shaky you get hungry you get tired you get irritable you lose focus
you just don’t function well you just don’t feel good until you can get some
more blood sugar so there’s two ways your body can do that it can release
cortisol which will start pulling from these glycogen stores again so you have
some carbohydrate stored and cortisol is released to raise blood sugar by pulling
from those stores but you can also raise blood sugar by eating sugar that’s the
fastest way so when you have a craving and there’s a vending machine around the
corner your body is gonna take you like a robot over to that vending machine and
you buy yourself a granola bar or a Snickers bar or a honey bun or something
like that so now your blood sugar shoots up again you
make a bunch of insulin your blood sugar drops you get another hypoglycemia and
then now we’ve reached noon and you’re ready for lunch so let’s look at what
actually happens here as far as storage so you wake up you have used 400
calories of carbs during the night you can store 400 if you ate six hundred for
breakfasts in between 8 a.m. and 10 a.m. you have used 200 calories of fuel the
extra 400 got into the bloodstream and then they were pushed out of the
bloodstream that means that they are stored the extra 400 stores so now your
glycogen stores are full and anything that you eat from this point is going to
be stored as fat so you eat another 400 which takes you through noon and now you
have burned 200 more but 200 has been turned into fat and they have been
stored now you go to lunch and you eat another 800 calories then by 3:00 p.m.
you have burned 300 calories in 3 hours but you ate 800 they’re no longer in the
bloodstream that means they got converted into fat so now you have 500
calories in fat stores plus the 200 in fat stores and because it was a big
lunch you make it all the way to 3 p.m. and then you have another snack maybe a
coffee and a doughnut maybe another Snickers bar and you make it all the way
to dinner and then you eat another 800 and so it goes so at the end of the day
you might have eaten 3000 calories which for most people might be a little too
much but why did you eat too much because you triggered insulin insulin is
fat storing in the presence of insulin which is fat storing you do not
have complete access to that fat you have trained your body away from using
fat into depending on carbohydrates so your body doesn’t know how to get to
this and therefore every time you need more blood sugar you get cravings and
you go like a hummingbird to top off your blood sugar every couple of hours
this is the problem with eating many small meals it’s better to eat many
small meals of low carb foods but that’s not what most people do and the best way
is not to eat carbs much at all and then what you find is you don’t really need
to eat many meals you don’t need to top off your blood sugar so let’s look at
how that works let’s say that you eat a very low carb diet that you’re fully fat
adapted your body knows how to burn fat for fuel now you wake up with a blood
sugar of about 85 that’s very very stable it’s a sweet spot that’s an ideal
blood sugar you wake up you have a cup of coffee with with some butter you have
some bulletproof coffee and even though fat doesn’t technically trigger insulin
it’s probably a trigger just a little bit anything that you eat triggers just
a little bit but you might go from 85 to 90 milligrams of blood sugar so no huge
reaction no roller coaster you your blood sugar is level and you’re just
coasting along and you don’t really get hungry to lunch ask people who have been
on a low-carb diet for a while they say I can’t make myself eat three meals a
day it’s just too much they eat when they get hungry and it’s not very often
so you get out to lunch and you eat a huge omelet with lots of cheese and
butter and good vegetables and some beans on the side and some broccoli eat
a thousand calories but it’s all low-carb so
your blood sugar doesn’t change much it might go from 90 to 110 but it never
gets to the point where you need a ton of insulin so now your blood Sugar’s
stay stable you burn a little you replenish a little you burn a little you
replenish a little the body doesn’t have to go through any convoluted mechanisms
of compensation to make things work so you coast along and you get out to
about six seven o’clock and you have dinner and the same thing happens you
eat low carb you eat a thousand calories and your blood sugar is stable so the
difference here is that you’re not gonna store the fat that you eat does not get
stored as fat it gets used it gets burned as energy because your body likes
to burn fat for energy and if you don’t trigger that insulin which is a storage
hormone you won’t store it over here he will just kind of float around in your
system and be available for energy what upsets the system is the blood sugar
roller coaster and that’s why you go to storing fat and not burning fat so in
our example of carbohydrates you ate 3000 calories but throughout the day you
stored 1200 calories each day as fat and as long as you keep this roller coaster
going and you develop insulin resistance you don’t have full access to this fat
so it doesn’t matter how many hundred thousand calories you have you you’re
rich in terms of fuel but you can’t get to it it’s it’s in the vault and the
lock for the vault is called insulin it’s like a vicious guard dog it just
keeps it in there so this is what we have to understand it’s not the calories
it is what happens to the calories depending on hormones so while this is
brilliant and geeky and I love it it’s works in a
physics lab it doesn’t work in biology because biology has additional rules on
top of physics and they’re called hormones hormones are triggered by
different foods fat does not trigger insulin carbohydrates trigger insulin
that’s the difference and hormones will change behavior they’ll change the
behavior of the cells the cells will store fat in the presence of insulin
they won’t store fat in the absence of insulin and hormones will change human
behavior they’ll change your focus they’ll change your hunger they’ll
change your cravings they’ll change your mood they’ll change your motivation
they’ll change your ability to stay on track so it is a whole lot more to it
then eat less and exercise more and keep breathing so now what you want to do is
you want to go watch that video because it’s hugely entertaining it has some
good information but keep this in mind and if you need a refresher then you
come back and you watch this again and you need to know this stuff well enough
that you can explain it to someone else because there’s a lot of people out
there that need to know this if you know a hundred people eighty of them are
insulin resistant and they’re heading toward a future of degenerative disease
because of it so share this with as many people as you can because this is
life-saving stuff and if you’re new to this channel make sure that you
