Your Brain on Ketones

– More ketones in your
blood does actually equate
to better brain function.
I’m Thomas DeLauer with Keto-Mojo
and a lot of times in talking about
how it’s not that important
to have super-high levels
of ketones, and in all entirety,
it’s really not, as long
as you’re in ketosis,
in that nutritional state of ketosis,
and you’re actively measuring
to make sure that you’re
there, you’re fine.
But when it comes down to the brain,
higher levels of ketones
do actually equate
to better brain performance.
You see, it has to do with
how the brain actually works
and utilizes different energy substrates.
Normally, when we’re on a traditional,
carbohydrate-filled diet,
our brain is running
almost entirely on glucose,
but once we start having ketones present,
the brain shifts gears
and actually utilizes
ketones as a fuel source
a lot more actively
than other parts of the body.
You see, for example, our
muscles can’t run on ketones.
The musculoskeletal system
needs glucose or oxygen,
but, for the most part, they’re
not really using ketones.
But when it comes to the
brain, we are using ketones.
Now, that doesn’t mean that
the brain doesn’t still use glucose.
Still about 25% or so of
the actual brain’s energy
is still derived from glucose,
but a vast majority of it
switches over to ketones
and it looks a little bit like this.
Your brain will preferentially run
on whatever is more prevalent.
So the more ketones that
you have in your blood,
there’s a direct linear equation
to how much of those ketones
your brain’ll actually use.
The lesser amount of
ketones in your blood,
the less your brain will use,
so it makes it really easy
when it comes down to math.
The higher your ketone levels,
the better your brain is functioning.
But there’s another system
that actually comes into play
that makes it really unique.
It’s called the
gamma-aminobutyric acid system
and the glutamate system.
It’s a pretty complex thing,
but I’ll break it down very simple here.
GABA is the system that allows your brain
to be a little bit more relaxed,
that gamma-aminobutyric acid system.
That is basically the calming effect
that allows your brain to just work
in a really systematic,
clean, methodical way.
Then we have the glutamate system.
Now, glutamate is exitatory,
so it triggers your brain to be
a little bit more hyperactive
and thinking in a little
bit of a different way.
So the glutamate system
and the GABA system
are both are really, really important
and we need to have an equal balance,
but ketones allow our
bodies and our brains
to be skewed a little bit
more towards the GABA side,
which allows us to think clearer
and be a little bit more
methodical with our choices.
That’s why it’s very, very common
for people that are on a ketogenic diet
to feel that sense of calmness,
but also feel like they
have the mental clarity
to allow them to achieve
whatever they need to achieve
in terms of their mental tasks.
So when it comes to down to knowing
how many ketones are in your blood
so that you can know how
your brain can perform,
it comes down to testing.
And that’s where Keto-Mojo comes in handy.
You can test your blood ketone levels
throughout the courses of the day
to know when your brain could
be operating at its best.
And the cool thing is
everybody responds differently
and everyday you might respond different
than you did the day
before, so it’s nice to know
when you’re in your sweet
spot and when you’re not.
So, as always, make sure you’re keeping it
locked in here with Keto-Mojo
and I’ll see you in the next video.
