Eat Less, Live Longer?
Yes, much hoo-ha over a “new” study which shows that calorie restriction in monkeys gives them that something extra. They age more slowly, look like young babes even though they’re senior citizens, and seem to have escaped the so-called age related diseases. An article in the LA Times is gushing over this discovery like it was the discovery of the proverbial fountain of youth.
But really, this is nothing new. Calorie restriction has been discussed and studies for decades. The article even says that:
Evidence has been mounting for years that the practice of caloric restriction — essentially, going on a permanent diet — greatly reduces the risk of age-related diseases and even postpones death. It has been shown to significantly extend the lives of yeast, worms, flies, spiders, fish, mice and rats.
A lot of people have also practiced calorie restriction, with varying results, although it is safe to say that the vast majority of healthy centurians are not overweight.
But what makes this study so special? Beats me as to why it is even news. The article goes on to say that the “study comes as some validation to the cadre of several hundred true-believing Americans who profess to practice caloric restriction in their daily lives.” Well, it may add more evidence, but again, this isn’t exactly a news-breaker. It’s just a repeat of what’s already been studied. This time it was done in primates.
Now, if it was a study with human subjects, and they had some profound results, that would be a different story. But all this study is doing is confirming findings of other research in non-human subjects, and still unable to answer a multitude of questions about calorie restriction. Should I or shouldn’t I?
