The Younger control monkey who eats ad lib looks significantly more frail and older than the older CR'd monkey. (click images to enlarge)EATING LESS, LIVING LONGER
Ricki Colman, PhD, reviews the long-term health benefits of caloric restriction (CR) using data from a 20 year study in non-human primates at the Wisconsin National Primate Research Center. She outlines positive health changes associated with longevity including lower diabetes incidence, less age-as sociated loss of muscle mass, altered energy expenditures, and lower rates of obesity. Low quality and high quality videos are available for those that can't watch on high.
This shows the survival of the control and Calorie restriction group at the moment. As you can see, the CR group are living longer. On the left they include all deaths, so this includes early accidental deaths from anaesthesia... which is not the important one we want to look at here. The most important thing is death from age related disease, and for this the CR group are showing the same results we see in other animals and are likely to live a few years longer.
This is the disease incidence of the primates on CR. Calorie Restriction completely prevents diabetes and this is true for all animals that are put on CR, including humans.
