Eat more, weigh less, live longer?
Clever genetic detective work may have pinpointed the reason why a near-starvation diet prolongs the life of many animals.
Ronald Kahn at Harvard Medical School in Boston, US, and his colleagues have been able to extend the lifespan of mice by 18 per cent by blocking the rodent's accumulation of fat in specific cells. This suggests that leanness - and not necessarily diet - promotes longevity in "calorie restricted" animals.
