Can what you eat determine how long, and how well, you live? The clinically proven answer is yes, and The Longevity Diet is easier to follow than you'd think. The culmination of 25 years of research on aging, nutrition, and disease across the globe, this unique program lays out a simple solution to living to a healthy old age through nutrition. The key is combining the healthy everyday eating plan the book outlines, with the scientifically engineered fasting-mimicking diet, or FMD; the FMD, done just 3-4 times a year, does away with the misery and starvation most of us experience while fasting, allowing you to reap all the beneficial health effects of a restrictive diet, while avoiding negative stressors, like low energy and sleeplessness.

Valter Longo, director of the Longevity Institute at USC and the Program on Longevity and Cancer at IFOM in Milan, designed the FMD after making a series of remarkable discoveries in mice, then in humans, indicating that specific diets can activate stem cells and promote regeneration and rejuvenation in multiple organs to significantly reduce risk for diabetes, cancer, Alzheimer’s, and heart disease.
