Mark Sisson on Metabolic Flexibility, COVID Missteps, and Eating Smart
Joe Rogan and Mark Sisson cover Mark’s move from California to Miami, using Florida’s COVID response as a springboard to critique lockdowns, public health messaging, and the neglect of metabolic health.
They dive deeply into diet science: why sugar and seed oils are damaging, why cholesterol and saturated fat are misunderstood, and how obesity, vitamin D, and blood sugar regulation affect COVID outcomes.
Sisson explains metabolic flexibility, keto, fasting, and his ‘Two Meals a Day’ approach as practical frameworks for fat-burning, immune resilience, and long-term health without obsessive dieting.
The conversation ranges into statins, agriculture and meat substitutes, exercise and recovery as we age, tech overreach, gene editing, homelessness, and the governance and decline of California.
Key Takeaways
Lockdowns ignored metabolic health, which likely worsened COVID outcomes.
Sisson argues that instead of only pushing lockdowns and fear, governments should have emphasized reducing sugar, getting sun for vitamin D, moving more, and managing weight and blood sugar—key factors in COVID severity.

Cholesterol is not the primary villain in heart disease.
He contends that modern research points to oxidation and inflammation—not cholesterol or saturated fat—as primary drivers of heart disease, and criticizes long-term statin use for side effects and marginal overall benefit.

Metabolic flexibility is more important than any single ‘perfect’ diet.
Rather than living in permanent ketosis, Sisson sees keto as a tool to train the body to efficiently burn both fat and carbs so you can fast easily, maintain energy, and occasionally enjoy higher-carb foods without derailing health.

Two meals a day with a long non-eating window can improve health.
By cutting out sugar, refined grains, and seed oils, then consolidating eating into roughly two meals within a 6–8 hour window, you can reduce total calories without constant hunger and activate repair processes like autophagy.

Seed oils and grains may be bigger problems than sugar alone.
Sisson believes industrial seed oils (soy, canola, corn, etc. ...

Combining lots of fat and sugar in one meal is especially harmful.
Eating a rich, high-fat meal and then adding a sugary dessert spikes insulin, locks fat into fat cells, and undermines fat-burning, making it one of the worst patterns for body composition and metabolic health.

Strength and muscle preservation become more critical than endurance with age.
Sisson, a former high-mileage endurance athlete, now prioritizes strength work, short intense efforts, and low-frequency but high-quality training to maintain muscle, organ reserve, and resilience into his late 60s.

Train by day, Joe Rogan podcast by night. All day. (instrumental music plays) All right, here we go. (instrumental music plays) Time flies, Mark.
It sure does, man.
How's it been five years?
A little over five years, yeah.
That's ridiculous.
I know. But-
I feel like I saw you, like, eight months ago.
I know, and the world has changed.
Yeah, a little bit.
(laughs)
Little bit.
Yeah.
And you're in Florida now. We were talking about this.
Yep.
I wanted to save it for the camera, 'cause you were gonna tell me how great you like Miami.
Well, um, you know, I, I grew up in Maine. And, uh, when I w- was in New England, Miami was sort of the place where, you know, only old people went, and it had all of the clichés behind it and I never really thought much about living there. And then when I lived in Malibu, I'm like, "Okay, this is, this is the cat's ass. This is the best place ever, Malibu." Well, um, much like yourself, Joe, I got a little bit disillusioned with California over the years, and, um, thought that I would, uh, try a different location, particularly one that didn't have any, uh, personal taxes. Uh, and, you know, we had gone to Miami Beach, uh, for a week every year for vacation, so we felt like we knew it. And then (laughs) we wound up, um, saying, "You know what? Let's try it for a year and see if we like it and we'll move out of California, and if w- it doesn't work, we'll move back." And I'm telling you, man, a year in, I'm like, "This is like summer camp and a spa and a playground every single day." I mean, the, uh, look, the water's 20 degrees warmer on any given day. The sand is nicer. The women are a little bit, you know, m- dressed a little bit more provocatively. Uh, I've got a great gym. Uh, I, I do stand-up paddling. Um, I've got an eFoil, an electric foil that I use, uh, a fat bike. Uh, I found a-
What's a, what's a fat bike?
A fat bike is a, is those, uh-
Fat tires?
... met- like, fat tire bike, yeah.
Oh.
We should, we should probably, given the current turn- tenor, we shouldn't probably call it a fat bike anymore.
Yeah, let's call it a fat bike.
It's more of, like, a, a pneumatically challenged bike. (laughs)
It's a male. It's okay. You can call it a fat bike-
That's right. (laughs) Yeah, yeah.
... 'cause it's a male. No one cares.
Exactly. Um, and so I ride in the, in the sand with some friends, and I, I ride with my wife. My wife has an electric one, so she can keep up with me. But I mean, it's, it's amazing. It's li- just like, like, every day, I feel like, you know, I'm a kid on vacation.
