In this episode of The Joe Rogan Experience, featuring Joe Rogan and Layne Norton, Joe Rogan Experience #1176 - Dom D'Agostino & Layne Norton explores ketogenic vs. High-Carb: Science, Performance, and Sustainability in Diets Joe Rogan hosts nutrition scientist and powerlifter Layne Norton and ketogenic researcher Dom D’Agostino for a deep dive into low-carb, keto, and high-carb diets. They agree that long-term weight loss and health are driven primarily by calorie balance and sufficient protein, not by any single macronutrient or diet ideology. Dom argues ketogenic diets offer unique metabolic and neurological advantages, especially for epilepsy, diabetes, the military, and appetite control, while Layne stresses individual preference, adherence, and anti-bullshit skepticism of overhyped claims. Together they explore metabolic adaptation, yo-yo dieting, carb tolerance, performance trade-offs, and why behavior and sustainability matter more than finding a “perfect” diet.
Ketogenic vs. High-Carb: Science, Performance, and Sustainability in Diets
Joe Rogan hosts nutrition scientist and powerlifter Layne Norton and ketogenic researcher Dom D’Agostino for a deep dive into low-carb, keto, and high-carb diets.

Key Takeaways
Calorie deficit and adequate protein are the primary drivers of fat loss.
Across dozens of controlled studies, when calories and protein are matched, low-carb and low-fat diets produce essentially identical fat loss and similar improvements in blood glucose and lipids; macronutrient split mainly affects preference and adherence.

The “best” diet is the one you can sustain long-term.
Most people can lose weight, but 70–95% regain it within three years; successful maintainers choose an approach—keto, higher carb, vegan, etc. ...

Ketogenic diets offer unique metabolic and neurological advantages for some.
Dom highlights evidence that nutritional ketosis can dramatically reduce seizures in epilepsy, stabilize blood sugar and insulin (especially in type 1 diabetes), blunt hunger via hormones like ghrelin, and provide efficient brain fuel that may help cognition and resilience in military and clinical contexts.

Metabolic adaptation makes repeated crash dieting progressively harder.
With each aggressive diet–regain cycle, resting metabolism drops and the body becomes more ‘fuel efficient,’ regaining fat faster and sometimes even increasing fat cell number, which helps explain why yo‑yo dieters struggle more over time.

Carbs, insulin, and sugar are not magic fat-gain switches.
Layne critiques the carbohydrate–insulin model, noting that obesity and insulin resistance stem chiefly from chronic overfeeding and inactivity; people can lose fat and improve health markers on both high- and low-carb diets as long as calories are controlled.

Individual responses to carbs, fat, and keto vary widely.
Some people feel and perform better on higher carb and lower fat; others do better on low-carb or ketogenic diets, especially those who report better appetite control and fewer blood sugar swings—genetics, psychology, and training all shape this response.

Discipline and environment matter more than dietary ideology.
Rogan repeatedly stresses that many failures come from lack of consistency rather than diet choice; both guests emphasize building habits, realistic pacing, and choosing strategies (like flexible dieting or low-carb) that reduce the willpower needed day to day.

Here we go. Four, three, oh, two, one. (claps) And we're live. Gentlemen, thanks for being here. Appreciate it. Um, let everybody know who you are. Layne?
Uh, I'm a meathead who likes science. (laughs)
(laughs)
Uh, got into bodybuilding when I was young. Uh, and then did a BS in Biochemistry, PhD in Nutritional Science. Um, kept lifting, did power lifting, won two national championships, got silver medal at worlds, set a then world squat record, and did also bodybuilding and won a natural pro card. They actually have natural bodybuilding, believe it or not. (laughs) And, uh, throughout that time just, you know, when I first got into it, one magazine said one thing and even in the same magazine, they'd have an article one month and the next month it would contradict it.
Mm-hmm.
So I was like, "I'm just gonna try and figure this shit out for myself." So-
Which is the place that a lot of people listening are at right now.
Yeah. And it's, it's tough 'cause it's kind of like, who do you trust?
Right.
Because no, not everybody has the time or the energy to go and do a degree in this stuff. So, but that was me. I kind of got down the rabbit hole of, all right, let's try and figure this nutrition stuff outAnd of course, the more I learned, the more I realized I didn't know. But, uh, yeah, it just became a passion for me to and to this day, I'm still very... I, I love this stuff. This is what gets me up, gets me going.
Well, guys like you are very important, guys who actually train very hard and really understand the science. This is 'cause it's usually one or the other.
Absolutely.
Yeah.
And I, like, when I was doing it, I, I graduated my PhD in 2010. When we started, we actually both knew each other from the bodybuilding.com message boards. So this was back before social media.
Trained together back in 2006 or 7, yeah, yeah.
7 at Experimental Biology.
Yeah, yeah.
So this big, there's a big symposium every year for science geeks.
(laughs)
And, uh, we were both going to it and we found out about each other on the forums and we went and trained together and he's a, he's a beast. Uh, and, uh, yeah, we really hit it off and we've been friends since then. So for everybody-
Awesome.
... who's looking for a fight, so- sorry.
(laughs)
We're probably gonna be pretty friendly.
Well, it's gonna be a conversation. We don't need to have a, a fight. And Dom, uh, you've been on the podcast before, but for people who didn't listen-
Yeah.
... to that one, please tell them who you are and what you do.
Yeah. Uh, um-
