Weight Loss Shown to Increase Libido

September 13, 2011

New research published in the Journal of Sexual Medicine found that a sexual benefit of weight loss for men is an increased libido. The study consisted of 31 men suffering from both obesity and diabetes, who were given reduced-calorie diets in an effort to lose weight and improve health. The men were divided into 2 groups: one group was provided with a liquid meal-replacement twice daily with a well-rounded dinner, and the other group was given low-fat, low-carb and high-protein meals.

The participants lost, on average, five to ten percent of their body weight over the course of the eight week study. Erectile function, sexual desire, and urinary symptoms all improved substantially, which was a key finding of the study. In addition, regardless of which of the two diets they were following, the men experienced improvements in insulin sensitivity, lipid profile and blood glucose.

Looking at the results per diet plan, the participants on the low-calorie dropped an average of 10% of their body weight after eight weeks, while the participants on the high protein diet averaged a 5% reduction in their body weight. At the conclusion of the study, weight loss averaged almost 30 pounds with the low-calorie diet and almost 12 pounds for men on the high-protein diet. The study findings indicated that for diabetic obese men, quick diet-induced weight loss reduces systemic inflammation and improves sexual, urinary, and endothelial function. Dr. George Fielding commented on the importance of the study. He said: "This recent study on improved male sexual desire and performance highlights a very important, but not much talked about, issue for all obese patients, namely their sexual function. Many patients, even young people, hint at this problem, but it’s usually glossed over." Dr. Fielding concluded: "This is an obvious benefit for our weight loss patients, and it can now be discussed with them, with some good scientific background information."

Dr. Mark Fusco, bariatric surgeon in Florida, agreed, adding "this is one more example of how varied are the beneficial effects of weight reduction. It's no wonder how we consistently see strong improvements in many facets of quality of life after weight reduction surgery."
