Well, we had a bunch of theories, but it really worked.

It was obvious that it worked.

And anyone who's tried it is like, oh, my God.

So I funded some research at the University of Washington, and both butter and this MCT oil, and I'll tell you about that in a sec, they change the thickness or the viscosity of the water so your cells can use it directly.

Now, who knew about this?

The Tibetans.

These people living at high altitude where there's no food, they would blend that butter into their tea.

They would never eat them separately.

And these little guys, half my size, would have a little bowl of barley with yak butter tea, and then they could pick up more than me, and they're walking around in T-shirts, and it's below freezing.

They had superpowers.

Well, they figured out that it was easier to mix the butter in the water than to do that inside the body, which is what we do when we eat butter and drink stuff.

So it was just a hack from ancient, ancient cultures, and I unpacked it.

And MCT oil is about 5% of what you find in coconut oil.

So if you think of coconut oil as a weak beer, MCT oil is Everclear.

It's highly concentrated.

And what MCT does, though, is it cannot be stored as fat, and it must be burned as energy.

And fat has more energy than carbohydrates.

So when people take this, it puts them in a mild form of ketosis, which is when your neurons in your brain are happy.

So we didn't understand why at the time, but if you blend grass-fed butter, MCT oil, danger coffee, blend it for 20 seconds and you drink it,

your brain starts sparkling, like you feel different and you just don't care about food.
