Valter Longo is an Italian biologist recognized worldwide as one of the leading experts on longevity and aging. He serves as Director of the Longevity Institute at the University of Southern California (USC) and has dedicated decades to researching how nutrition influences human lifespan.
His studies on fasting-mimicking diets and caloric restriction have been published in the most prestigious scientific journals globally, establishing him as an undisputed authority in the field of gerontology.
According to Longo's research, animal-based proteins contain certain amino acids that may accelerate cellular aging.
Excessive consumption of these amino acids activates metabolic pathways such as mTOR (mammalian Target of Rapamycin), which is linked to:
Longo suggests substituting or reducing animal proteins with plant-based sources:
Plant proteins have a more balanced amino acid profile and do not activate aging pathways as intensely.
Valter Longo developed what he calls the "Longevity Diet", based on his research on the world's longest-living populations and laboratory studies. The fundamental pillars include:
Predominantly plant-based diet, fish 2-3 times per week, minimal animal proteins.
12-hour daily eating window and periodic 5-day fasting-mimicking protocol.
Regular exercise, 7-8 hours of sleep, and stress management.
| Term | Definition |
|---|---|
| mTOR | Protein that regulates cell growth. Excessive activation is linked to accelerated aging and diseases like cancer. |
| IGF-1 | Insulin-like growth factor. High levels are associated with increased risk of age-related diseases. |
| Fasting-Mimicking Diet | Special 5-day diet that reproduces fasting benefits without complete food restriction. |
| Autophagy | Cellular cleaning process that removes damaged components. Activated during fasting. |
Important note: Longo's recommendations are backed by decades of scientific research, but always consult a healthcare professional before making significant dietary changes.
