EurekAlert notes that MIT researchers are claiming the first molecular link between eating and aging. Professor Leonard Guarente says that "for the first time, this study gives us a glimpse of how calorie restriction works at the molecular level. And it will ultimately lead to health benefits in people." This stems from a greater understanding of the mechanisms associated with a single protein, Sirt1, that controls fat storage and release in the body. The eventual goal of this and similar research is to produce therapies that replicate the health and life-extending benefits of calorie restriction without the need for dieting.
