Eat less, live longer! Calorie restriction leads to weight loss and longevity. The more one eats, the more free radicals they will generate, the more their bodies will have to detoxify and remove bi-products of digestion and metabolism both systemically and cellularly. The benefits of reducing calories goes beyond just the weight loss that occurs. Calorie restriction/reduction may be the best form of life insurance we can get, and it's free.
