Studies have shown that restricted eating can improve longevity. Researchers found that those who experienced the least weight loss while eating less had the greatest longevity benefits. Eating less food or less frequently improved lifespan in mice more than periodic fasting. Mice on very low-calorie diets lived longer, regardless of body fat or glucose levels. Maintaining body weight and immune cell health during stress or low food intake was linked to longer lifespans in mice. Genetic factors played a larger role in lifespan than diet. It was found that losing weight on caloric restriction was actually bad for lifespan. Balanced calorie restriction may be the key to long-term health and lifespan.
