I've read all those studies that tell us that we are so much better off if we reduce our calorie intake, and Im delighted to find one that disagrees!It's with rhesus monkeys...but hey, that's pretty close.
A 23-year study of caloric restriction in rhesus monkeys shows that this type of diet does not increase their lifespan. Yay , for those of us who like food.
The results, published online in Nature, contrast with other studies that have shown that restricting calorie intake (by 10–40% of a nutritious diet) can extend lifespan in various species. However, the results do suggest that calorie restriction may have some health benefits.
The National Institute on Aging study aims to verify whether the life-prolonging effects of calorie restriction observed in lower organisms also occur in monkeys and thus, might plausibly translate to human ageing. Starting to restrict monkeys’ caloric intake at older ages (around 16–23 years old) did not increase survival, but did improve the health and function of their metabolism, Rafael de Cabo and colleagues report. Young monkeys on a caloric restriction diet showed a trend towards a delay in age-associated disease onset, but again, no increase in lifespan. Considering the differences between their findings and the result of similar studies, the authors propose that the effects of caloric restriction in long-lived animals are not straightforward. They suggest that a variety of environmental, nutritional and genetic factors may also affect how calorie restriction affects longevity.
