Coming up on today's show.

Mark Bell, some of you might know him, started the sugar diet.

He's a big time influencer, historically low-carb keto.

I ended up losing a lot of weight doing low-carb keto, and he started posting about the sugar

diet.

He's saying he's losing fat and not losing muscle and his exercise performance is fantastic.

I'm going to have to relate this to a new human controlled trial that was published

in one of my favorite journals Nature Metabolism. Basically what they did in this study is they took

lean, healthy med, so men generally in their 20s, BMI around 25. They put them on a protein

restricted diet that was high carb and generally low fat. So over five weeks, what ended up happening

is a remarkable 19% increase in total energy

expenditure without changes in physical activity. 5754 more calories burned when they were eating a high

carb, low protein, low fat diet. It's quite remarkable. What I think it is is an opportunity

to use a viral fad diet to understand really cool metabolism that underlies

not just that, but other ways in which we can look at diets, even ketogenic diet.

So I think it's a really cool trend.

I'm not going to do it myself, but I hope people try to understand it rather than just dismiss it as stupid.

Nick, it's coming up on a year since we last chatted.

In that time frame, in the research realm, in the metabolic health realm, what has got

you most excited?

First of all, thanks for having me back, Jesse.

I can't believe it's been a year.
