Today we're going to talk about what would happen to your brain if you ate no sugar for 21 days.

That's three weeks.

And I've done a lot of videos on how sugar impacts the whole body.

Today we're just going to focus in on this brain.

It's fascinating.

And this video was inspired by a research paper out of the Journal of Clinical Endocrinology

and Metabolism.

And this study revolved around doing the ketogenic diet for three weeks and what it does

to the brain, just to three weeks, it's mind-blowing.

It increased the blood flow to your brain by 22%.

Now, you might at first say, well, 22% doesn't seem like a lot,

but let's say you're an Olympic athlete and you're running around the track and someone just

turned up the oxygen by 22%. Just think of the advantage of what 22% more oxygen could do

in a race. We're talking about a significant boost in oxygen and nutrients to your brain. Even if you

think when you exercise, if you were to restrict your oxygen by 22%, you would feel it. I mean,

just think about if you go to sleep at night and someone turns down the blood flow and turns down

the oxygen by 22%. Well, they actually call that sleep apnea.

You're not going to sleep that great.

You're going to wake up feeling tired.

Well, just by going on low carb, you can increase your blood flow significantly.

And there's something else that's really cool.

Your BDNF increases by 47%.
