35 分钟Welcome to Huberman Lab Essentials where we revisit past episodes for the most potent and actionable science based tools for mental health,
physical health and performance.
I'm Andrew Huberman and I'm a Professor of Neurobiology
and Ophthalmology at Stanford School of Medicine.
This podcast is separate from my teaching and research roles at Stanford.
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.
Today we are going to talk about two hormones, thyroid hormone and its related pathways, and growth hormone and its related pathways,
which arguably are the two hormones and two systems in the body that are most significant for setting your overall level of metabolism.
So metabolism is the consumption of energy, not necessarily eating, but it's the use of energy in the cells of the body for growth of tissues,
for repair of tissues, and also just for day to day maintenance of function.
These two hormones, thyroid hormone and growth hormone, we think of as related to metabolism of things in the body,
keeping body fat low and keeping muscles strong and tendons strong and repairing themselves, et cetera.
But they are also key for brain function,
for the ability to maintain cognitive function throughout the lifespan.
So the the big theme I'd like to introduce is that metabolism isn't just about losing weight,
but having a high metabolism, provided it's not too high, is great.
It means that you will have more lean tissue, more bone and muscle, and less adipose tissue fat.
And we know that that's healthy.
There are neurons in your brain in an area called the hypothalamus,
