The Best Diet May Just Be the One You Can Actually Live With, Says This Fitness Expert

If you’ve ever white-knuckled your way through a diet, only to rebound hard the moment you loosen the reins, Jeff Cavaliere knows exactly why. The Athlean-X founder told neuroscientist Andrew Huberman on a recent episode of the Andrew Huberman Podcast that most men don’t fail because they’re weak—they fail because the plan they’ve chosen is impossible to live with.

“You’re not just changing your diet, you’re changing your habits, you’re changing your lifestyle,” Cavaliere, who has over 14 million subscribers on his highly popular YouTube Channel, says in their conversation. “So when you go and you start making these radical changes to your nutrition plan because you’re on a diet, it does not work.”

Cavaliere’s main tip for struggling dieters: stop chasing extreme, short-term fixes and build a way of eating you can run on for years. For him, that looks like a protein-first “clean omnivore” approach. He builds every meal around a lean protein source—chicken, fish, beef—then fills the rest of the plate with mostly fibrous vegetables and some starchy carbs like rice or potatoes.

Crucially, he refuses to demonize foods he knows he’ll never give up. Pasta and oatmeal stay in. So does the occasional carrot cake. Instead of banning favorites, he manages portions and balances the plate. That’s his definition of nutritional freedom: learning the calorie and macronutrient impact of different foods so you can make “equivalent swaps” on the fly and stay on track in any setting.

“I’ve been doing what I’ve been doing here now with my nutrition approach for 30 years,” he says. “It wasn’t super easy in the beginning… but I was willing to go slowly, and not sacrifice the things that I really knew I wouldn’t be able to live without. Therefore, I can live with it forever.”

The Clean Omnivore Solution to the 23-Hour Problem

Huberman, who dubs this style “clean omnivore,” argues that this shift—from diet labels to sustainable structure—is exactly what most guys need. “What you described, what I’ll just call clean omnivore, is… an awesome way to approach nutrition,” he tells Cavaliere. “Once people make that switch, they’re really in the driver’s seat.”

For men who keep starting over every Monday, Cavaliere’s message is simple: The one-hour workout isn’t the problem. It’s the 23 hours that follow. If your current plan leaves you feeling deprived, obsessing over “cheat meals,” and cycling between restriction and blowouts, it’s not a willpower issue—it’s a design flaw.

The fix: Build your diet around lean protein, vegetables, and carbs you actually enjoy; respect calories, especially from fats; and choose an eating style you can repeat calmly, not perfectly, for the next decade—not just the next eight weeks.

For Cavaliere, that’s the real metric of a good diet: not how shredded you can get in a month, but whether you can still eat this way, without resentment, 30 years from now.
