Long-term, Substantial Weight Loss and Insulin Regulation of Lipolysis

Summary

It is not known how much improvement in insulin regulated lipolysis (the breakdown of triglycerides) occurs following substantial, sustained weight loss. Researchers will test the effects of inflammation and lipolysis regulation in people before and after bariatric surgery (sleeve gastrectomy) to answer these questions.
