Sexual function improved significantly and quickly in obese men with type 2 diabetes after weight loss with reduced-calorie diets, results of a small Australian clinical study showed. Erectile function, sexual desire, and urinary symptoms all improved significantly in 31 men who lost 5% to 10% of their body weight in eight weeks. Metabolic parameters, including blood glucose, insulin sensitivity, and lipid profile, also responded favorably to either a low-calorie, meal-replacement diet or a high protein-low carbohydrate diet, according to an article published online in the Journal of Sexual Medicine. The improvements were maintained during a year of follow-up.
