A long-running study is re-affirming the life-extending benefits of calorie-restricted diets. It overturns a study from 2012 indicating otherwise. The 25-year experiment shows that rhesus macaques, when eating 30% less than normal, are twice as likely to live beyond those who could eat whatever they want.

Shockingly, Canto, who is on a CR diet, is 29, while Owen, who receives pellets consisting of 30% sugar, is 27. Credit: University of Wisconsin-Madison, photo by Jeff Miller.
