The Effect of Rimonabant on Energy Expenditure, Fat Metabolism and Body Composition

Summary

This study will determine in obese subjects the direct effects of the weight loss drug rimonabant (ie independent of weight loss) on energy expenditure, fat metabolism and and body fat distribution. We hypothesise that rimonabant will increase energy expenditure. The fuel for the increased energy expenditure will come from fat. As a result of burning more fat there will be a decrease in fat in blood and an improvement in the body's response to insulin.
