NCT00260143
Men infected with the HIV virus (the virus that causes AIDS) often lose weight even though they may try to eat more food to gain weight. The reasons for this weight loss are not clear. Many men with HIV have low levels of testosterone in their blood. Testosterone is a hormone that is naturally produced in the bodies of both men and women and has important effects on building muscle and bone mass. The purpose of this study is to find out if providing additional testosterone to HIV infected men who have low testosterone can help them gain weight, increase their muscle mass, and feel better. The study will also help see if testosterone improves the efficiency with which your body produces and uses energy including fat. The dose of testosterone being used in this study will raise testosterone levels in the blood to higher than normal levels (2-3 times normal level).

Obesity is a major health problem in the US and many Western countries, with more than half of the population being overweight or obese. Yet, despite intense research efforts into the mechanisms underlying obesity and into the development of novel pharmacologic interventions, bariatric surgery, including gastric bypass surgery is the only successful treatment for severe obesity. Mimicking one of the effects of bariatric surgery, e.g. the increased secretion of glucagon-like peptide 1 (GLP-1) could be an effective strategy against obesity. Obese individuals may be more sensitive to the rewarding aspects of food and less responsive to signals from the gut about actual energy needs. Using functional MRI scanning the investigators plan to examine the effect of Exenatide (a GLP-1 analog known to reduce caloric intake and produce weight loss in both obese and lean individuals) on activity within brain regions/networks involved in reward/motivation and in regulation of energy requirements. The investigators expect the peptide to change the balance between desire to eat for pleasure and the need to eat to maintain homeostasis.
