A study conducted by exercise physiologists in the University of Alabama at Birmingham (UAB) Department of Human Studies finds that as little as 80 minutes a week of aerobic or resistance training helps not only to prevent weight gain, but also to inhibit a regain of harmful visceral fat one year after weight loss. The study was published online Oct. 8 and will appear in a future print edition of the journal Obesity.

The American College of Sports Medicine (ACSM) has published its Position Stand "Appropriate Physical Activity Intervention Strategies for Weight Loss and Prevention of Weight Regain for Adults," updating its previous guidelines, particularly as it relates to the increased levels of physical activity that may be necessary for prevention of weight gain, for weight loss and for prevention of weight regain.
