TRUE ✓

TL;DR ·Dr. Valter Longo leads extensive research at USC focused on fasting and cancer treatment.

WHAT WE FOUND

Dr. Valter Longo is the director of the Longevity Institute at the University of Southern California (USC) . He has led numerous studies at the university investigating how fasting and fasting-mimicking diets (FMD) can prevent and treat cancer . Research from Longo's laboratory indicates that these dietary interventions can delay tumor progression and increase the efficacy of chemotherapy through both immune-dependent and immune-independent mechanisms . His work further demonstrates that fasting can protect healthy tissues from chemotherapy-associated toxicity while potentially weakening cancer cells . These findings are supported by both in vitro experiments and randomized clinical trials conducted under his leadership at USC .
