Finally, science is figuring out how we're going to shrink our guts and end the nation's obesity epidemic: We simply have to stop eating for sixteen hours at a time, every day, for the rest of our lives. The approach really seems to be working for mice, anyway. A new study by the Salk Institute finds that mice restricted to eating a high-calorie diet only during an active eight-hour period, then refused food during the rest of the day, are nearly as trim as a sample of mice kept on a low-calorie, low-fat diet. (A third group of mice could eat whatever they wanted, whenever they wanted, and they quickly became a bunch of fatasses.) "We have to come up with something that is a simple alternative to calorie counting," the study's lead biologist tells the L.A. Times. And while starving ourselves is easier than counting calories, it's also idiotic.
