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.

Expert discussions with Dr. Walter Longo

Longo: How a structured fasting-mimicking diet targets the aging biology behind chronic disease
Aging biology may influence chronic disease risk as broadly as many major risk factors studied in epidemiology. A structured 5-day fasting-mimicking diet may push healthy and cancer cells toward different metabolic stress responses in some people. The protocol is meant to support standard care, not replace it.
Valter Longo: Growth hormone, GLP-1, and fasting for healthy aging
Pushing your body to grow faster, with growth-hormone drugs or high protein, may speed up aging rather than slow it. The same drugs that build muscle or drop weight quickly can carry a long-term cost. Cycling between normal eating and short, planned fasting periods may offer repair without that cost.
