Abstract
Weight loss is an important concern for the US population. Consumers spend $33 billion annually for weight loss products and services.1 Despite these expenditures, overweight and obesity have been increasing in the United States.2,3 Although long-term weight loss is difficult to achieve, research suggests that changes in both diet and physical activity are important to long-term success.4-6 For losing weight, both the US Department of Agriculture's Dietary Guidelines and the National Heart, Lung, and Blood Institute's Clinical Guidelines recommend decreasing calorie intake and increasing physical activity.6,7 Both guidelines recommend at least 30 minutes or more of moderate physical activity on all or most days of the week for all Americans.Keywords
