Researchers Say Low-Cal Diet Cuts Aging

CBS News reports:

Longevity researchers say they've shown for the first time that following a strict low-calorie diet can decrease DNA damage linked with aging.

Some people who took part in the six-month diet study ate as little as 890 calories a day. Their insulin levels fell and metabolisms slowed _ changes that are thought to increase longevity.

The findings are provocative, but preliminary. Longer-term research will try to sort out whether such changes can meaningfully extend people's lives, said senior author Eric Ravussin of the Pennington Biomedical Research Center at Louisiana State University.

Eating less would help a whole lot of people.
