New Study Suggests A Minimum One-Hour Workout May Be Necessary

New research suggests that older women who are at a healthy weight may need a minimum of one hour of moderate activity per day to stay in shape. Women who are overweight may need even more exercise to "avoid gaining weight without eating less," according to the CBS News article "Study: 1-Hour Workouts Needed to Fight Fat."

The study's results, which appear today, April 7, in the Journal of the American Medical Association, is "based on 34,079 non-dieting middle-aged women followed for about 13 years. The women gained an average of almost 6 pounds during the study." Only women were included in the study and "researchers from Harvard's Brigham and Women Hospital said it's uncertain whether the results would apply to men."
