I did not mean to imply that, I just wanted to make the point that eating less is not always good advice, in particular in the age bracket that suffers from age related muscle loss.
You're right, and there's always exceptions to the rule. Eg some of those with life threatening injuries probably need processed food in the interim. But the general point stands which is that human longevity had been correlated with caloric restriction. Even in Ben Franklin's wit and wisdom, he remarks that to preserve one's life, one should eat less. This observation is timeless
I don't think caloric restriction has been shown to increase lifespan in humans. It works very well in the mouse model, but iirc monkeys don't benefit (as much?).
