Summary
Brief summary
The study hypothesis is that inhibition of cholesterol absorption complements the effects of weight loss on lipid and lipoprotein transport in obese subjects. Specifically , the study aims to elucidate the mechanisms of action of a new therapeutic regimen (weight loss plus ezetimibe) for regulating lipid and lipoprotein transport in these subjects.
