The Genome News Network is running a good article on calorie restriction (or CR), a diet and lifestyle choice that has been proven to have strongly beneficial effects on health, resistance to age-related disease, and healthy life span. The evidence for CR has been getting steadily more compelling over the past few years as the underlying genetics and biochemistry have been brought into focus. If you are serious about your health, you owe it to yourself to look into calorie restriction. A good place to start (aside from the introduction here at the Longevity Meme) is the website of the Calorie Restriction Society. You'll find friendly e-mail lists, recipies, books and much more.
