Does physical activity ameliorate the health hazards of obesity?

Abstract

Obesity is an established risk factor for chronic disease and premature death, but losing weight and keeping it off is difficult. Therefore, although obese individuals may know that they are at higher risk of disease and early death, they still may not be able to lose weight and maintain weight loss. Perhaps health professionals should focus less on weight and more on how to enhance and maintain health for people of all sizes and shapes.
