Even though hangry is one of these pop culture kinda words
that we use you know, playfully sometimes seriously
there is a scientific or a biochemical underpinning to it.
So basically the three macronutrients as you know.
We eat our carbs, our proteins, and our fats
and these three macronutrients in our food
get broken down into fuel.
Carbs get broken down into simple sugars
and the sugar is primarily the number one fuel source
for our body particularly by the way our brain.
Your brain, right. Absolutely.
What I wanna do is I wanna show you over here,
I have a little set up here of how this actually works.
So when you eat food stuffs it gets stored
into different places through our body like so.
So it's gonna go into our fat.
It's gonna go into our liver.
And it's gonna go into our muscles.
And these are the places where our body stores
the sugar when we're not using them.
So when you do not have enough sugar your body will go back
into these fat stores, Into--
or these liver stores,
or muscle stores-- Okay.
And take in the energy and be able to use it for energy.
Now why does it make people angry
to have to use their reserves?
Because what happens is if you don't have many,
so look at all that, those food stuffs that we have.
If you only have maybe one or two and it starts to slow down
then your body gets to what's called
a fight-or-flight response.
Your body starts-- I see.
To think on my goodness something is wrong,
it becomes stressful to your body,
and that then translates into our blood sugar.
So let me show you the blood sugars and we're gonna get
to that because that deals with two hormones.
So now the average person does not obviously
have this at home.
This is a blood glucose test but basically
you take a little machine like this,
diabetics typically do this almost once or twice a day,
you pinch it like so, you get a little squirt of blood
and we did this backstage already.
So you take a little blood here and you put it here
and then you put it inside the machine like this
and it gives you a reading.
Okay now I'm gonna show you-- But people should not be--
No, no, no-- If you're not a diabetic
you don't need to do this. But I wanna show you
what it looks like on screen
so the typical blood sugar range is between 70 and 140.
Okay? Okay.
This is a random test.
Mine backstage was 84 okay so it's fine.
Now one of the issues happens is,
if your blood sugar gets too low then your body feels like
it is in a stressful environment and because of that
it releases two hormones, adrenaline,
otherwise known as epinephrine.
So you've heard people say wow I got a lot
of adrenaline going I'm really excited.
So you release adrenaline and something called cortisol
which is your stress hormone.
Those things are important because that is what
the body does when it looks like
it's in a fight-or-flight response.
However one of the by-products of having these hormones,
which you need by the way
because it helps your sugar get back up,
one of the by-products is you get stressed.
You become anxious.
You become grumpy.
And you just start snapping at people.
That is one of the side effects
of the cortisol and the adrenaline.
But you need the cortisol and adrenaline
because they will go into your organ systems
and bring the sugar back up so your levels go above the 70.
Typically when your level your blood sugar levels go down
to about 80 is when you start feeling
hangry-- Getting hungry.
Yeah exactly. Right.
It varies per person.
So it's almost time for you to eat you better go.
That's right (laughs).
So we talk about these stress hormones,
adrenaline and cortisol, and I wanna show you what it does.
So everyone obviously does not have a glucose meter at home
but there are some signs and symptoms
that you can look at to see if it's happening.
So one thing for example is your eyes will start
to get dilated so your eyes, your pupils will dilate
as a result of these hormones.
The other thing that happens is and this is very true,
your heart rate right here will increase
so you start having fast heart rate
and your blood pressure throughout your body will increase.
And these are all part of the fight-or-flight response
based on these hormones.
So by not eating a regular diet
you're actually putting burden
on literally your organs, your blood pressure,
everything. 100%.
And also your muscles throughout your body,
they will also increase in tension,
because once again these are the adjustments
that your body makes in case it has to fight-or-flight.
So these are the, so this is what you'll notice
at home if you don't have a meter of course.
