Title: 12 Months Weight Loss Study Using Feedback Messages Delivered Via Smartphone
Brief Summary: The overall purpose of this randomized clinical trial is to examine the effect and efficacy of the individualized, real-time, smartphone-based feedback of diet and physical activity self-monitoring on subsequent weight-control behaviors, weight loss outcomes and sustainability of patient engagement. Participants will be randomized to one of 2 groups: (1) Self-Monitoring -similar to what many people do on their own, subjects will self-monitor diet, physical activity using Fitbit and weight using a Bluetooth-enabled scale, and (2) Self-Monitoring +Feedback-participants will self-monitor as described for the Self-Monitoring group but also will receive tailored Feedback messages. The Self-Monitoring +Feedback participants will receive up to 4 daily discrete pop-up Feedback messages on the participant's smartphone delivered at random times during waking hours and tailored to content of recorded entries in the subjects' smartphone-based diaries and a weekly summary Feedback message about the participant's weight.
