Burning fewer calories: the elixir for longevity

New research shows that humans and other primates burn 50% fewer calories each day than other mammals. The study, published January 13 in the Proceedings of the National Academy of Sciences, suggests that these remarkably slow metabolisms explain why humans and other primates grow up so slowly and live such long lives. The study also reports that primates in zoos expend as much energy as those in the wild, suggesting that physical activity may have less of an impact on daily energy expenditure than is often thought.
