Counseling for physical activity in overweight and obese patients.

Obesity has reached epidemic proportions in the United States. More than 60 percent of U.S. adults are now overweight or obese (defined as at least 30 lb [13.6 kg] overweight), predisposing more than 97 million Americans to a host of chronic diseases and conditions. Physical activity has a positive effect on weight loss, total body fat, and body fat distribution, as well as maintenance of favorable body weight and change in body composition. Many of the protective aspects of exercise and activity appear to occur in overweight persons who gain fitness but remain overweight. Despite the well-known health and quality-of-life benefits of regular physical activity, few Americans are routinely active. Results of research studies have shown that physician intervention to discuss physical activity (including the wide array of health benefits and the potential barriers to being active) need not take more than three to five minutes during an office visit but can play a critical role in patient implementation. This article describes elements of effective counseling for physical activity and presents guidelines for developing physical activity programs for overweight and obese patients.
