  • Obesity


Overweight and obese adults recruited from the primary care setting (n=150) will be enrolled in a 6-month randomized trial of the INTERVENTION versus CONTROL. Both groups will receive usual medical care, printed materials, and educational text messages. The INTERVENTION group will also receive personalized coaching and feedback, as well as peer support, via text message. The investigators hypothesize that compared to those in the Control group, patients in the Intervention group will lose more weight and demonstrate more favorable changes in fruit and vegetable intake, exercise, and social support for weight loss.
