Ben Greenfield And Joe Rogan Dive Deep Into Diets, Longevity, Performance
Joe Rogan and Ben Greenfield cover a wide-ranging set of topics centered on diet personalization, anti-aging strategies, performance optimization, and recovery methods.
They debate carnivore, vegan, and ancestral-style diets, emphasizing gut health, elimination diets, microbiome balance, and genetic individuality in nutrition.
Greenfield details cutting‑edge and experimental longevity tactics—NAD and stem-cell therapies, peptides, photobiomodulation, cold/heat exposure, and fasting—while stressing natural foundations like sleep, movement, and breath work.
The conversation also explores strength and doping science, cannabis and performance, ergonomic work setups, hunting and spearfishing, and practical sleep and recovery tools like CBD and sauna.
Key Takeaways
Use elimination diets as temporary tools, then reintroduce foods intelligently.
Carnivore-style eating can rapidly reduce inflammation and autoimmune symptoms by removing irritants, but Greenfield suggests using it for gut healing (8–12 weeks) and then gradually returning to a diverse, well-prepared diet rather than staying meat‑only long term.

Prepare foods traditionally—soak, sprout, and ferment—to reduce plant toxins and improve digestion.
Problems blamed on gluten, lectins, and grains often stem from modern processing; slow-fermented sourdough, properly prepared legumes, and traditional methods can neutralize many problematic compounds and make these foods beneficial instead of harmful.

Personalize your diet and supplements using genetics, blood work, and glucose data.
Greenfield advocates testing ancestry, APOE status, vitamin levels, food reactivity, and continuous glucose to tune macronutrients (e. ...

Prioritize heat and cold exposure for longevity and performance—but start naturally.
Finnish-style dry saunas are strongly linked to lower mortality and better cardiovascular and brain health, while cold immersion boosts adaptation and recovery; Greenfield recommends using natural hot/cold (sauna, lakes, showers) first and only then considering infrared saunas or cryo chambers for detox or convenience.

Be cautious with pharmaceutical anti-aging drugs like metformin; consider natural mimics.
Although metformin is popular for longevity, Greenfield flags side effects (mitochondrial inhibition, B12 issues, GI distress) and instead prefers glucose- and inflammation‑modulating compounds such as berberine, curcumin, apple cider vinegar, cinnamon, and bitter melon to achieve similar effects with less downside.

Use structured fasting that’s sustainable instead of extreme calorie restriction.
His approach combines daily 12–16‑hour fasts, a quarterly 5‑day reduced‑calorie “fasting-mimicking” phase, and one or two 24‑hour fasts per month, focusing on compressed feeding windows for autophagy and metabolic benefits while still allowing robust calorie intake and training.

Master breath work and sleep hygiene before resorting to pharmaceuticals.
Greenfield strongly prefers techniques like slow breathing, box breathing, and CBD, plus light control and fiction before bed, over Ambien or Valium, which can severely disrupt deep sleep, memory consolidation, and brain detox processes such as glymphatic drainage.

Notable Quotes
““I don’t know that there’s a lot of components of the carnivore diet that are actually healing the gut as much as it’s the absence or elimination of the foods that were harming it.””
— Ben Greenfield
““I don’t want to live a long time if I can’t kick ass and feel good.””
— Ben Greenfield
““Nutrition is highly religious and dogmatic.””
— Ben Greenfield
““The best position to be in when you’re working would be whatever position you’re not in at the moment.””
— Ben Greenfield
““Once you deny the human body’s ability to be able to heal itself or to be able to decrease stress on its own, you begin to rely on these exogenous chemicals—that’s where you start playing with fire.””
— Ben Greenfield

Hello-
Index finger.
... Ben.
Hello.
What's up, buddy?
There's a discrepancy. My, my coffee is way, way bigger than yours. (laughs)
Uh, what's this?
I've got, like, this 40-ounce Big Gulp French press.
Yes. Um-
Versus the... Is that a Caveman?
Yeah.
Cold brew.
Nitros.
Yeah. Those are pretty good too.
Yeah. I love them.
Those pop the punch.
Yeah.
Yeah.
Dude, thank you so much for the bread and the macaroons and-
(laughs) The goodies?
Yeah. That's, that's awesome.
They... I... I would-
Awesome stuff.
I would probably be morbidly obese if I wasn't an exercise freak, but, uh-
It seems like it.
Yeah. Yeah. Jessa makes that sourdough bread and it is fricking amazing.
Did you do that carnivore diet thing? Did you try that out?
No.
You didn't?
No.
No.
I like meat, but I didn't do the carnivore diet.
I thought you were gonna do it for a certain-
No.
... amount of time and test it.
I thought about it. (laughs)
(laughs)
I'm too much of a foodie. I'm t- Like, I... What I did was I tried to eat rib eye steaks every night for dinner.
Mm-hmm.
So I did, like, a 33% carnivore diet. But, uh, there was a study actually that came out, it was just, like, two days ago, on that TMAO.
Mm-hmm.
The, the sugar that is associated with gut damage when you're eating a, a high red meat diet.
Right. When your body-
And-
... takes excess protein and it turns it into sugar.
Right. With, theoretically, the idea being that that might be present because your microbiome is imbalanced from a diet that's too heavy in meat if you weren't getting enough fiber.
Is it a microbe... It's, it's because of your biome? I thought it was just because of glucogenesis, because y- your body has nothing but meat, your body turns it into glucose.
No. That w- That would be something different. That, that-
Oh, really?
That conversion to glucose is a different sugar than the TMAO.
Oh.
So what the TMAO is, is that's gonna be present if you aren't getting enough fiber or if your biome-
Ah.
... is imbalanced. But what this study, uh, a couple of days, looked at was people who were eating, like, a fish and egg and plant-rich diet, and they had high levels of TMAO too, but they weren't deleterious. They're actually protective-
Because of the fiber?
... because they had the fiber.
Mm-hmm. Interesting.
Yeah. I mean, you could do... You could do a carnivore diet if you were... There, there's a few populations that do this, like in, in Spain. I forget the name of the sausage, but they'll, like, eat the, they'll eat the ruminant. Like, they'll eat the, the intestine of the ruminant-
