Calorie Restriction is pretty much the only proven way to extend life and slow down the aging process. The only source for this I've seen so far is the wikipedia page and according to it: There are ongoing studies on whether CR works in primates. So unless you are a yeast or a fish, it is not proven. Exercise and a healthy diet on the hand are proven.
