Researcher on diet and aging, University of Wisconsin-Madison
Studies how protein and single amino acids in the diet affect metabolism and lifespan. His lab has reported that restricting the amino acid isoleucine improved metabolic health and extended lifespan in mice. He is a scientific advisory board member of Aeovian Pharmaceuticals, which is developing drugs that block the growth signal mTOR.
WHAT TO WATCHWhether his group or others run longer human studies of lower-protein diets that track signs of aging.
Two Wisconsin researchers pulled together hundreds of studies on eating less protein. Animals often lived longer. In people, the data is short-term and nobody has measured lifespan.
