Researchers have uncovered evidence that suggests people consuming fewer calories each day may live longer.

For some time there has been evidence that laboratory mice and rats fed fewer calories live longer. George S. Roth and his team at the National Institute of Aging have now reported preliminary evidence that biological changes that help create super-aged rodents may also work in humans, reports the New York Times.
The biological markers – lower temperature, lower insulin levels and a steady level of a steroid hormone called DHEAS – all occur in restricted-diet rodents that live about 40% longer than fellow rodents on a normal diet, said Roth. The same biological markers have now been found in men who are living longest in a continuing study in Baltimore on aging.
However, as Roth stressed in a journal appearing in this week’s Science, the results are preliminary and, nobody should start starving themselves in an attempt to live longer.
Even if the evidence proves to be correct, it’s unknown how much extra time people might live.
