Starving Doesn't Work

From Reuters:

Starving -- officially known as caloric restriction -- may make worms and mice live up to 50 percent longer but it will not help humans live super-long lives, two biologists argued on Sunday.

They said their mathematical model showed that a lifetime of low-calorie dieting would only extend human life span by about 7 percent, unlike smaller animals, whose life spans are affected more by the effects of starvation.

This is because restricting calories only indirectly affects life span, said John Phelan of the University of California Lo Angeles and Michael Rose of the University of California Irvine.

Researchers at various universities and the national Institutes of Health are testing the theories but there are groups already cutting calories by up to a third in the hope they can live to be 120 or 125, while staying healthy...
