Brief Summary

The purpose of this study was to examine whether 4 consecutive weeks of phone coaching aids in recovery from weight regain during weight loss maintenance. Individuals who previously achieved and maintained a \>=5% weight loss in a 1-year behavioral weight loss program were provided with a low-intensity maintenance intervention (monthly newsletters and smart scale). At baseline, participants were randomized to the coaching group or the control group (no coaching). If participants regained \>1.5% of their weight, randomization was "triggered." At this point, participants randomized to the coaching condition received 4 brief weekly coaching calls; participants randomized to the control condition received no additional intervention contact. Short-term and long-term weight change was assessed and compared between treatment groups.

EXPERIMENTAL

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).

ACTIVE COMPARATOR

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.

Phone coaching BEHAVIORAL

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.
