The purpose of these studies is to gain an understanding of the mechanisms that promote weight loss and improved glucose control. The ultimate goal is to identify therapeutic pathways for obesity and diabetes as a way to optimize surgical procedures and discover novel non-surgical targets for safe and effective drug therapy. Participants with obesity will…
We are recruiting healthy volunteers, aged 18-65, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to induce temporary insulin resistance in 10-12…
