Valter Longo, PhD

PhD from UCLA, Edna M. Jones Professor of Gerontology and Biological Sciences, and Director of the USC Longevity Institute. Developed and clinically trialed the fasting-mimicking diet (FMD). Disclosed commercial interest: he founded and holds an ownership stake in L-Nutra, maker of the commercial FMD kit ProLon; he donates consulting fees and most of his equity to charity, but the financial interest is real, and his content here is graded against the published trial evidence, never against his own product line.
