Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Maintenance program+possibility of phone coaching

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).

Group Type EXPERIMENTAL

Maintenance program

Intervention Type BEHAVIORAL

1-year weight loss maintenance program, consisting of monthly newsletters

Phone coaching

Intervention Type 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.

Maintenance program only

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.
