The purpose of this study is to determine the feasibility of providing incentives to people enrolled in a weight-loss program for dietary self-monitoring and/or interim weight loss.
In this study, community outpatients will participate in an effective, 24-week, low-carbohydrate weight loss program delivered via biweekly group classes. An innovative information technology (IT) solution will collate dietary self-monitoring data (input by patients via a mobile phone dietary application) and weight loss data (input by patients via remote scale). An algorithm will classify participants as achieving adequate or inadequate dietary self-monitoring and weight loss to earn intermittent rewards of varying value in real-time. Participants will be notified of earning rewards via text messaging.
