According to JAMA, among women consuming a usual diet, physical activity was associated with less weight gain only among women whose BMI was lower than 25.

Dr. Michael Roizen, Cleveland Clinic Chief Wellness Officer, answers the question "How much exercise is enough?"

2. Resistance exercise for 30 minutes a week.
3. 20 minutes of cardiovascular exercise.
