Are you between 18 and 50 and have obesity? This study is examining whether obesity causes chemical changes to DNA that affect the amounts of certain proteins that your body makes. These changes in protein levels may raise the risk of heart and blood vessel diseases in people who have obesity. The study will test whether regular physical activity and weight loss surgery can help reverse these changes to DNA. This study takes place in Chicago, Illinois.
