About the expert
Focus: Fasting-mimicking diet and longevity
Dr. Walter Longo is professor and director of the Longevity Institute at the University of Southern California. He developed the fasting-mimicking diet (FMD) and has published extensively on caloric restriction and lifespan extension spanning yeast models to human clinical trials. His work links periodic fasting to stem cell regeneration and reduced disease risk factors.
Why this matters
Academic longevity researcher who studies how growth signals, fasting, and diet shape aging; tends to view restraining growth pathways as central to long life. Strongest on the totality of animal and population evidence, but has commercial ties to the fasting-mimicking diet he recommends, so weigh his program-specific claims with that in mind.
