What's that?

One is exercise.

One is exercise.

Which I love.

And not just any.

It's more of the hard type.

Two, and this is why I'm fasted right now, is the ketones that are produced during ketosis.

So again, you have to be fasted for anywhere between 12 or more hours to start to really use fatty acids as energy and that energy you're, you're making ketones and the ketones is actually what's used as energy.

Well, the ketones are not just a clean energy source.

They're also a signaling molecule.

It's a mode of communication between your body and other parts of the body, like the brain.

So it's basically your body's way of telling your brain, Hey,

this is a stressful situation.

I don't have any food.

By the way, humans throughout, you know, like however, you know, many thousands or millions, whatever you believe, however the earth is, you know, we were always, you know, we were subject to periods of no food, right?

And we didn't always just have Instacart and Postmates and things that were easily available to just get food.

So it's an adaptation that's in our genes.

And what happens is these ketones that are produced signal to the brain, it's a stressful time,

I need to, for one, make more brain-derived neurotrophic factor.

This is a neurotrophic factor that's involved in learning, in memory, in producing more neurons, but also in what's called neuroplasticity, the ability of your brain to change and adapt to a changing environment.
