Daily 2-Mile Walk May Prevent Impotence

More Exercise, Less Eating, Can Reverse Erectile Dysfunction in Obese Men

June 22, 2004 -- You may be willing to walk the ends of the earth to find true love. But when it comes to maintaining good sex, the trek is much shorter. A new study shows it takes just two miles a day.

That's all it takes for some obese men to reduce their risk of erectile dysfunction -- or even "reverse" current impotence, report Italian researchers.

"In our study, about one-third of obese men with erectile dysfunction regained their sexual function after two years of adopting healthy behaviors, mainly regular exercise and reducing weight," they write in this week's Journal of the American Medical Association.

And the workout to help iron out problems below the belt? According to the researchers, "sedentary men may be able to reduce their risk of erectile dysfunction by adopting regular physical activity at a level of at least 200 calories a day, which corresponds to walking briskly for two miles."

Dual Approach Is Best

The researchers wanted to determine how healthy lifestyle interventions could help improve erectile dysfunction in obese, middle-aged men who did not have heart disease, diabetes, hypertension, or other conditions known to cause erectile dysfunction.

Along with exercising two hours a week, half of the 110 men studied were placed on a calorie-restriction diet in which their average caloric intake dropped from 2,340 to 1,950 calories daily. Their prescribed diet boosted their fiber intake and they substituted saturated fats with monounsaturated and polyunsaturated fats.

The other half were given general information about healthy food choices and exercise, but not placed on any specific regimen.

After two years, the men advised to lose weight saw little improvement -- in either weight loss or sexual function. But the men who ate less and exercised more lost about 15% of their weight. What's more, one in three regained sexual function.

"We must say that the program which the obese subjects agreed to enter in was based on an integrated approach, so, we don't know if adopting one aspect only (diet or exercise) could be effective," says study researcher Katherine Esposito, MD, of the Center for Obesity Management at Second University of Naples.

"Our feeling is that diet and exercise are both important," she tells WebMD. "Our advice to such a man would be, eat well and move more."
