Calorie restriction extends lifespan in primates
« on: August 02, 2015, 07:11:57 PM »
Somehow I missed this when it came out.  Calorie restriction has previously been shown to extend lifespan in a wide variety of animals from microbes to rats.  Now that result has been extended to primates - specifically, rhesus monkeys.  A 30% calorie restriction resulted in about a 20% increase in lifetime when looking only at age related deaths, and about a 10% increase in lifetime when other causes of death were included.

Caloric restriction (CR) without malnutrition increases longevity and delays the onset of age-associated disorders in short-lived species, from unicellular organisms to laboratory mice and rats. The value of CR as a tool to understand human ageing relies on translatability of CRs effects in primates. Here we show that CR significantly improves age-related and all-cause survival in monkeys on a long-term ~30% restricted diet since young adulthood.
