Exercise and weight loss may improve sexual function in obese men. In a recent research study of more than 100 obese men with erectile dysfunction, nearly a third regained normal sexual function after participating in an intensive weight loss programme. In the 2-year study, researchers form the University of Naples followed 110 obese men with erectile dysfunction. Half of the men were randomly assigned to participate in an intensive weight-loss program that included individualised advice on boosting exercise and improving diet. The other half received general information about healthy eating and exercise, but did not receive any individualised guidance. By the end of the study, men in the intensive group achieved significant weight loss, along with improvements in several health indicators, such as blood pressure and cholesterol levels. 17 men (31 percent) in the intensive group regained sexual function by the end of the study, compared with just 3 men in the other group. The researchers concluded that lifestyle changes, including a reduced calorie diet and increased exercise, improves erectile dysfunction in obese men.
