Why Plant-Heavy Diets May Build Long Life but Weaker Bodies
This work suggests the type of protein in a low-protein diet may matter as much as the amount.
Low-protein, Mediterranean-style eating is linked to long life, but it can leave people physically fragile. This commentary highlights work showing that adding a moderate amount of the amino acid methionine to a low-protein diet cut body fat and reduced frailty in animals. It worked through a hormone chain involving growth hormone, GLP-1 and FGF21, without cutting calories. So protein quality, not just how much you eat, may matter for aging well.
