A calorie restriction (CR) human interest piece from the Baltimore Sun: "Scientific studies in the 1930s showed that mice on an extremely low-calorie but healthful diet lived 30 percent longer and also seemed to age more slowly. Ever since, researchers have been trying to figure out whether a [calorie restricted] diet that was also rich in nutrients would extend human life. Further animal studies and research on small groups of humans have been encouraging, and this month scientists at Louisiana State University reported an extremely low-calorie diet can reduce the DNA damage of aging. ... News stories about the science of calorie restriction often focus on practitioners who eat almost nothing and whose weight is dramatically lower than what's considered normal. But many people who believe it will extend life practice calorie restriction to a lesser degree."
