37 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.
And now for my discussion with Dr. Lane Norton.
Dr. Norton, thank you so much for being here.
This is a long time coming,
and I have to say, as a fellow PhD scientist, I feel a great kinship with you.
I know you have tremendous experience in fitness and nutrition and a number of areas.
I'd like to start with something that's rather basic and yet can be pretty complex.
And that's this issue of energy balance and energy utilization.
What happens when we eat food of any kind?
And how is that actually converted into energy as a way of framing
up the discussion around weight loss, weight maintenance, weight gain and body composition?
It's a great question.
And like you said, this is one of those things where, you know, people use the term calories and calories out.
And they say, well, that's way too simplistic.
And I'm like, if you look at what actually makes up calories and calories out, it's actually very complicated.
So a calorie just refers to a unit of energy of heat specifically.
Really what you're talking about is the potential chemical energy
that is in the bonds of the macronutrients of food, right?
