Exactly What David Sinclair, Ph.D., Ate To Look & Feel 10 Years Younger

David Sinclair, Ph.D., was 48 years old when a blood test showed that his body's "biological age" was actually 10 years older. A Harvard geneticist and professor of the biology of aging, he became passionate about how he could reverse this biological anomaly. Spoiler alert: He did it.

Sinclair recently sat down with mbg co-CEO Jason Wachob to reveal how he was able to turn his health—and biological age—around. (Be sure to tune into the podcast for the full discussion.)

We're big on gut health here at mindbodygreen, and so is Sinclair. We know a healthy gut is essential to longevity, which is why Sinclair says he always has a supply of his favorite yogurt on hand: Bravo Yogurt.

Of course, it couldn't be a conversation about longevity without a mention of plants (and lots of them). For Sinclair, he's a big proponent of dark leafy greens. "So that would be, unfortunately, kale," he jokes. "I say 'unfortunately' because lots of people don't like kale. I think baby broccoli is good. All that good, leafy stuff. I also would do Brussels sprouts."

Another way to support a healthy gut as we age, as well as a healthy brain, is getting your healthy fats. For Sinclair, who went through the '90s anti-fat fiasco, realizing he could still enjoy healthy fats was a breakthrough.

"I used to avoid fat like the plague because of recommendations from nutritionists. I would love to get my childhood back, to be able to eat that stuff. [Now] I eat cheese, and I eat yogurt. And I think I'm healthier than I ever was. But you can't eat the same quantity of cheese as you do plant food. You'd just gain too much weight."

And as far as his favorites, Sinclair says, "If I eat meat, I eat fish if I have a choice. And then I take my omega-3s. I always have a couple of avocados in the fridge or on the table. Avocado oil is fantastic for sure. And olive oil, I'm becoming more and more convinced is the thing to do, so I've always put liberal amounts on bread and on salads."
