Today's interview on Redefining Medicine features biochemist Valter Longo, PhD, Director of the Longevity Institute of the University of Southern California. Longo has created the nutritional breakthrough Fasting Mimicking Diet (FMD), designed to provide the body with natural, nourishing ingredients, while not activating any of the pro-aging processes. As FMD has rapidly gained traction and recognition across the globe, Longo's endeavors represent the very forefront of modern medicine, and have changed how clinicians advise patients regarding wellness and longevity.
