It also isn't clear whether caloric restriction would extend human lives by very much, UCLA evolutionary biologist Jay Phelan said. He has combined results from animal studies with data on men on the Japanese island of Okinawa who ate 17% fewer calories than men in Tokyo. He calculated that reducing intake by 35% would extend the human life span by just two years.

Two years is two years, but still -- if that's the payoff for a life of starving and denying yourself, I'm not all that impressed.
