Why can cutting your daily caloric intake increase your lifespan?

Humans can't live reasonably by cutting 30 or 40 percent of their calorie intake like a laboratory rat put on a calorie-restricted diet, because all they would think about is food. Fortunately, just cutting back by 15 percent gets you almost as much of an anti-aging benefit as going on a more severe calorie-restricted diet. This is why you can incorporate this approach instead of the tougher 25 percent reduction that is often used by calorie restriction zealots.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
