The Longevity Diet: Carbs Aren't The Enemy

We have all met people who look curiously years or even decades younger than they actually are; Dr. Valter Longo explains his theory regarding why that is—and, in particular, how food can impact the difference between your chronological age (the number of years you have been alive) and biological age (the age at which your body functions and appears to be).

The director of the Longevity Institute at the University of Southern California and the Program on Longevity and Cancer at IFOM in Milan, Longo has devoted his career to researching aging, disease and how to optimize health and longevity through nutrition.

His international bestseller, “The Longevity Diet” proposes that sticking to a plant-based pescatarian diet and implementing periodic fasting-mimicking techniques—nutritional programs that cause effects on metabolism and cellular function similar to those caused by water-only fasting—a few times a year is the best recipe for living longer, living better and even looking better. “What you put into your body—nutrition—makes a major difference,” he says. “We think a plant-based pescatarian diet, which is associated with longevity, can likely affect the look of the face and skin.” Below, his advice on how to have a long life, age gracefully, and even have a little dessert every night.
