Among women consuming a usual diet, physical activity was associated with less weight gain over 13 years only among women of normal weight, according to a study in the March 24/31 issue of JAMA. The researchers also found that women successful in maintaining normal weight averaged approximately 60 minutes a day of moderate-intensity activity throughout the study.
