Eating less can help you lose or maintain your weight, but it looks like it can also add years to your life. Well, at least that's the case for monkeys. A 20-year long study on Rhesus monkeys found that those who cut their calorie intake by 30 percent slowed down signs and diseases of aging, and lived longer than monkeys who ate more. The dieting monkeys had less cancerous tumors, heart disease, and less brain shrinkage. They also looked younger than the non-dieting monkeys.
Scientists have known that eating less over time has lengthened the life of more primitive creatures such as worms, flies, and mice. Now this news of larger mammals benefiting from a low calorie diet is inspiring the question — What about humans? Could calorie restriction help us prevent disease and lengthen our lives? Scientists aren't sure yet but the evidence seems convincing. If it turned out to be true, do you think you could live on 30 percent less calories a day for the rest of your life?
