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?
