A WebMD article comments on recent work that reinforces the science behind the protective effects of calorie restriction. This isn't really news to anyone who has been following CR science for a while: low calorie diets have long been shown to protect against cancer in animals. In addition, a wealth of data exists to link human obesity - or even just excess weight - to greatly increased risk for cancer (as well as just about every other unpleasant age-related condition you can think of). If you haven't done so already, I think you owe it to yourself to look into calorie restriction. Improve your longevity and you'll be more likely to benefit from the future of real anti-aging medicine!
