What to Expect

If you want to join the study, you will come in for 2 to 3 visits to see if you qualify. At these visits, we will check your vital signs, weight, height, and body fat. You will get a physical exam, an ECG (a test that checks your heart), wear 2 different sleep trackers for 1 to 7 days, complete a 7-day sleep log, and have your blood taken to check that you are healthy enough to join the study. If you qualify and decide to join, you will take part in a 6-month weight loss program. The program includes group meetings that help you make changes to your eating, activity, and sleep habits. A registered dietitian will lead the meetings. For the first 3 months, the group will meet every week. Then, for the next 3 months, the group will meet every other week. During the program, you will work on eating fewer calories, being more active, and improving your sleep. You will have 6 more in-person visits, 2 before the program starts, 2 in the middle of the program, and 2 after it ends. At these visits, we will check your weight, blood pressure, body fat, and take a blood sample. You will also wear a monitor that tracks your physical activity and sleep three times during the study, each time for one week. For three days in a row, you will take pictures of everything you eat and drink and text them to the study team. You will also be asked to participate in one 90-minute focus group so that we can hear about your experience in the study.

Study Duration

You will have 7 to 8 in-person visits during the study. The study will last about 9 months.
