Longevity & AgingFasting as Regenerative Medicine: What Dr Valter Longo's Research Reveals
Longevity researcher Dr Valter Longo makes the case that precise, short-term fasting isn't a wellness trend — it's a form of regenerative medicine. His fasting-mimicking diet (FMD), a carefully designed five-day protocol, appears to trigger autophagy, reduce insulin resistance, and activate tissue repair programs that resume powerfully during refeeding. In clinical trials on prediabetes and type 2 diabetes, 60–70% of patients reduced or eliminated medications within a year. Longo also critiques GLP-1 drugs like Ozempic for causing muscle loss alongside fat loss, arguing that working with the body's evolved biology outperforms overriding it pharmacologically. He warns against the cultural tendency to eliminate biological effort entirely, suggesting that some forms of metabolic stress are essential to long-term health.
