The Effects of Lifestyle-modification Induced Weight Loss on Metabolic and Inflammatory Profile, Endothelial, Sexual and Urinary Function, and Quality of Life in Obese Men

This study aims to evaluate the extent to which weight loss of 5-10% from baseline, induced by exercise and diet, improves metabolic and inflammatory profile, endothelial function, erectile function, sexual desire, lower urinary tract symptoms (LUTS), and quality of life in obese men.

This study aims to evaluate the extent to which weight loss of 5-10% from baseline, induced by exercise and diet, improves metabolic and inflammatory profile, endothelial function, erectile function, sexual desire, lower urinary tract symptoms (LUTS), and quality of life in obese men.Men aged 30-65 years, with body mass index (BMI) ≥ 27.5 kg/m2, will be recruited from referrals to the Sports Medicine Centre in Changi General Hospital. The study will be conducted at the Sports Medicine Centre by trained medical investigators, dieticians and sports trainers.At baseline, 12 and 24 weeks, fasting glucose and lipids, insulin, testosterone, sex-hormone binding globulin, serum C-reactive protein and interleukin-6 are measured, endothelial function is measured by the non-invasive EndoPAT method, and validated questionnaires administered to assess changes in erectile function, sexual desire, LUTS and quality of life
