Valter Longo
Biogerontologist · The Longevity Diet
Director of the Longevity Institute at USC, where his lab traced how nutrients and fasting switch the genes that set the pace of aging. He is best known for the fasting-mimicking diet, a five-day plan developed in that lab, and for The Longevity Diet, the book built on it. He grew up between Genoa and Calabria, played guitar in a rock band before biochemistry took over, and donates his book proceeds and consulting fees to two foundations he set up.

LongoBacked by 1 of 54 stacksUnder 65 he argues for protein that is low but sufficient and mostly from plants, pointing at the growth pathways his lab has tied to aging.
