Cutting calories and eating at the right time of day leads t
One recipe for longevity is simple, if not easy to follow: eat less. Studies in a variety of animals have shown that restricting calories can lead to a longer, healthier life. Now, new research suggests that the body's daily rhythms play a big part in this longevity effect. Eating only during their most active time of day substantially extended the lifespan of mice on a reduced-calorie diet.

In this study of hundreds of mice over four years, a reduced-calorie diet alone extended the animals' lives by 10 percent. But feeding mice the diet only at nighttime, when mice are most active, extended life by 35 percent. That combo—a reduced-calorie diet plus a nighttime eating schedule—tacked on an extra nine months to the animals' typical two-year median lifespan. For people, an analogous plan would restrict eating to daytime hours. The results suggest that time-restricted eating has positive effects on the body, even if it doesn't promote weight loss.
