About

Many adults with obesity continue to gain weight even though they do not want to. This project will test the effects of a primary care intervention in which people with obesity receive an electronic scale and recommendations to weigh themselves daily. This will help us understand whether daily self-weighing might be a way to prevent continued weight gain.

Enrollment: 396 patients

Sex: All

Ages: 19 to 65 years old

Volunteers: Accepts Healthy Volunteers

• Resides in one location at least 5 days each week
• Possesses a smartphone with data plan
• Wi-Fi or Bluetooth internet connection in home

Exclusion criteria

• Pregnancy or anticipating pregnancy during study duration. This is a weight loss study and weight gain/loss due to pregnancy and/or delivery would confound study results. Additionally, weight loss is not recommended for pregnant women.
• Unwilling or unable to do any of the following: give informed consent, accept random assignment, attend five measurement assessments
• Likely to relocate and no longer be seen at UAB primary care in the next 2 years
• Weight loss ≥5% of body weight in past 6 months (other than postpartum)
