|Description||Caloric restriction (to 60-80% of ad lib levels) increases mean and maximum life span of laboratory rodents (eg Weindruch and Walfor, 1988). A study on rhesus monkeys was begun at the National Institute on Aging in 1987 to study the effects of caloric restriction (by 30%). There were three groups at the beginning of the study: juvenile, adolescent, and old (Ingram et al, 1990). Another study of adult-onset caloric restriction was begun in 1989 at the University of Wisconsin, Madison (Kemnitz et al, 1993). The results, on aging, are still pending.|
|Other Phenotypes||Rhesus monkeys on caloric restriction have lower body temperature, fasting blood glucose and insulin, and serum triglycerides and cholesterol (Lane et al, 1999). They are more sensitive to insulin than ad lib fed controls and have increased HDL2B (Lane et al, 1999). They have reduced body fat and lower blood pressure (Lane et al, 1999).|
