calorie restriction

For years, Donkey Kong has been trying to snuff out Super Mario, but with no luck. So maybe he should try cutting back on his bananas.

A new study found rhesus monkeys--a distant cousin of Donkey Kong--stayed healthier and more youthful on a calorie-restricted diet.

The research, first reported on in 2006, tells the tale of two rhesus monkeys, Canto age 27, and Owen age 29, both with two very different diets.

I distinctly remember speaking with an unknown elderly couple many years ago while seated next to them at a restaurant. I don't recall what started the conversation, but I do know that it had something to do with food. At any rate, the husband and wife -- both of whom looked rather healthy, despite the fact that they were in their late 80s -- proudly stated that the key to their longevity was not eating. "Huh?," I muttered through a mouthful of pasta primavera, only to be told once again by these fine people -- who dined only on small bowls of soup -- that they attributed their long lives to eating very, very little food.
