I've seen this claim several times in connection with different studies. I believe the hugest benefits apply to organisms that eat a restricted number of calories for all or most of their lifespan. And it's probably not only the number of calories, but also the quality of food that matters. Nutrient-dense, low-calorie diets could be worth a try, but how long could you stick with them?
