That has to do with the short chain fatty acids being good for the gut.

I think malate's awesome.

And I always try to eat green apples.

They're really high in malic acid and tart cherries.

Tart cherries are really high in it as well.

So today I did three minutes at 49 degrees Fahrenheit.

I have a cold tub.

I definitely do cold when I'm going to do a podcast.

when I'm going to give a talk or when I'm anxious, I feel good, I feel more focused, which is why I usually do it before any type of public speaking.

But I want to be cold adapted because that means I have more mitochondria in my adipose tissue and perhaps even muscle, like that's been shown.

Shivering is a very inefficient way to produce heat, which is what your body's trying to do when it's exposed to cold.

And your muscles are basically contracting and producing heat from that, but that's just not very efficient.

So the...

more eloquent way to do it, or elegant, I guess, way to do it is to basically have your mitochondria produce tons and tons of heat.

So mitochondria are these little organelles inside of your cells that are responsible for producing energy.

Usually that's in the form of adenosine triphosphate, ATP, and that's what...

lets everything function inside your body from your neurotransmitter production to your heart beating, et cetera.

Basically your mitochondria, they're like a little battery.

So they have, well, they have a double membrane, first of all, their structure, but they have a negative charge on the inside and they have a positive charge on the inner membrane.

Basically you can uncouple that charge.
