Summary

This episode discusses metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanisms and tools grounded in specific mechanisms are discussed.

Welcome to the Huberman Lab podcast where we discuss science and science-based tools for everyday life.

0:09.0

I'm Andrew Huberman and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine.

0:15.2

This podcast is separate from my teaching and research roles at Stanford.

0:18.6

It is however part of my desire and effort to bring zero cost to consumer information about science and science-related tools to the general public.

0:26.2

In keeping with that theme, I'd like to thank the sponsors of today's podcast.

0:30.7

Our first sponsor is Forcigmatic.

0:34.4

Forcigmatic is a wellness company that makes mushroom coffee.

0:37.7

And if you're asking yourself why would you want to put mushrooms in coffee?

0:41.0

First of all, let me tell you these are not psychedelic mushrooms and know the coffee doesn't taste like mushrooms.

0:46.6

The coffee is delicious and you don't taste mushrooms at all.

0:50.1

I know this because I've been using Forcigmatic coffee and been stalking it in my laboratory for several years now long before I ever had the podcast or Forcigmatic was a sponsor.

1:00.5

The two kinds of mushrooms that are in Forcigmatic coffee are lion's mane and chaga mushrooms, both of which have been shown to have a slight angziliotic effect to reduce anxiety.

1:10.1

And lion's mane has also been shown in several studies to lower the symptoms of depression just slightly, although I wouldn't consider it a treatment for depression.

1:18.8

That's an attractive benefit as well as have some affected offset and cognitive decline, albeit slightly the effects were real in the studies that I found.

1:28.3

So if you'd like to try Forcigmatic, you can go to Forcigmatic.com slash Huberman.

1:33.4

That's F-O-U-R-S-I-G-M-A-T-I-C dot com slash Huberman.

1:38.9

And if you do that, you'll get 40% off your order plus free shipping on mushroom coffee bundles.

1:44.3

That's Forcigmatic.com slash Huberman for up to 40% off and free shipping.

1:49.4

Today's episode is also brought to us by Blinkist.

1:52.8

Blinkist is an app that has thousands of nonfiction books condensed down to just 15 minutes of key takeaways that you can read or listen to.

2:00.1

I'm a big reader and I'm a big consumer of nonfiction.

2:03.9

And most of the time I consume books in their traditional form like a book where you flip the pages and so forth.
