Welcome back to the Diet Doctor podcast. I'm your host, Dr. Brett Scher. Today I'm joined by

Dr. Kevin Hall. Now, Kevin has a PhD in physics from McGill University, and he is the senior

investigator at the National Institutes of Diabetes and Digestive and Kidney Diseases at the NIH

in Bethesda, Maryland. And he's pretty active on Twitter at Kevin H. underscore Ph.D.

Now, Kevin has a reputation and well-deserved as being sort of one of the more

preeminent researchers currently mechanisms of weight gain and loss.

He also seems to have found himself in the middle of what seems to be this fight between

the energy balance model and the carbohydrate insulin model.

And personally, I like to see where we have common ground between those.

And I think he does a good job of describing how energy balance isn't calories and calories out. It's not that all

calories are the same, which is sometimes sort of a misconception of the energy balance model.

So he talks about what he thinks are the most important aspects of the energy balance model

for gaining and losing weight. We talk about some things like resting metabolic rate, which is basically how many calories

your body burns at rest.

We talk about physiologic adaptation.

And we talk about how his research, what is its role sort of in the bigger scheme

weight gain and weight loss research?

Because they are short trials. They are very,

very well, very meticulously controlled trials. And does that apply to a clinician trying to help

a patient or an individual trying to make a decision for themselves over the long run?

How it may or may not play into that larger picture. And I think he's very upfront about limitations of his

studies and benefits of his studies and it fits into that picture. So I think that's an interesting
