Calorie Restriction Mechanism Uncovered?

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

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.
