TIME On Calorie Restriction
TIME Magazine is running an article on calorie restriction and its beneficial effects on health and longevity. The last couple of years of research into calorie restriction has uncovered an array of fascinating biochemistry relating to metabolism, stress, hormones, aging and genetic regulation. The current goal for many scientists is to produce calorie restriction mimetic drugs that replicate the health benefits and extended healthy life span without the need to diet. It's worth noting that the lack of excess body fat in practitioners of calorie restriction could explain some of the health benefits - but given that being overweight greatly increases your risk of suffering age-related disease, that sounds like another good reason to be practicing calorie restriction!
