Phone Coaching for Weight Loss Maintenance

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine whether weight loss maintenance can be improved by providing individuals with 4 consecutive weeks of phone coaching during the maintenance period. Individuals who previously achieved and maintained a >=5% weight loss in a 1-year behavioral weight loss program will be provided with a low-intensity maintenance intervention. Some individuals will be selected to receive phone coaching. Assessments of weight, physical activity, and other weight-related behaviors will occur at baseline, 6 months, and 1 year.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Maintenance program+possibility of phone coaching<br>All participants are provided with a monthly newsletter which contains useful strategies for maintaining weight loss long-term. Participants are also encouraged to weigh themselves daily using a smart scale, which electronically transmits weight data to the research staff. Some participants randomized to this condition will also receive 4 consecutive weeks of phone coaching at some point over the 1-year intervention period (this is determined by a weight-based algorithm). | Behavioral: Maintenance program<br>* 1-year weight loss maintenance program, consisting of monthly newsletters<br>Behavioral: Phone coaching<br>* Some individuals will receive 4 consecutive weeks of phone coaching. The first coaching call will be approximately 30 minutes in duration and follow-up calls will be 10-15 minutes in duration. Coaches will help support participants in their weight loss maintenance efforts. Once coaching calls are completed, the participant will not have any other contact with their coach.<br>|
| Active Comparator: Maintenance program only<br>All participants are provided with a monthly newsletter which contains useful strategies for maintaining weight loss long-term. Participants are also encouraged to weigh themselves daily using a smart scale, which electronically transmits weight data to the research staff. No participants in this condition will receive phone coaching. | Behavioral: Maintenance program<br>* 1-year weight loss maintenance program, consisting of monthly newsletters<br>|
