These days, we hear a lot about fasting. Intermittent fasting, time-restricted eating, and water fasting are just some of the many terms being thrown around in support of better health. And we can’t forget about the high-fat, ketogenic, and low-carb approaches that are gaining in popularity as well. Which one is best? What does it all mean for our longevity, brain health, and overall wellness? My guest on this week’s episode of The Doctor’s Farmacy is here to sift through the terminology and confusion around fasting.Dr. Valter Longo is internationally recognized as a leader in the field of aging studies and related diseases. Known as a “Guru of Longevity,” Dr. Longo is currently Professor of Biogerontology and Biological Sciences and Director of the Institute of Longevity of the School of Gerontology at the University of Southern California in Los Angeles, as well as Director of the Oncology and Longevity Program at IFOM in Milan.
