You're listening to Bulletproof Radio with Dave Asprey.

Today's cool fact of the day is about hummingbirds.

It turns out that amongst all the animals with a backbone in the animal kingdom, the

one with the very highest metabolic rates of the hummingbird, when they're hovering,

there are about 10 times the metabolic rate of what a human can do on a pound for pound

basis.

Most of the diet comes from sugar, things like nectar, and they would be considered

diabetic if they were humans.

But to burn through that sugar so rapidly, they keep their wings fluttering 60, 80 times

a second, and eat so much food so fast, as they burn it, that they eat one and a half

to three times their weight and nectar in insects per day.

And the ruby-throated hummingbirds have a metabolism 100 times that of a big animal like

an elephant, which is kind of cool because we're all animals.

We all run on mitochondria, but there are some serious differences between how we sense

the environment and how we use what we get in the form of food and light and all the

other signals to tell our bodies what to do, which is why.

As you can well imagine, I've been mastering the art of foreshadowing lately.

We might have something to do with metabolism in today's episode.

And that's because today's guest is a guy I referenced heavily in Headstrong, my book

on Cognitive Function and mitochondrial hacking.

And his name is Dr. Frank Schellenberger.

He's been practicing as a position for more than four decades in conventional and alternative
