Brief summary
The primary aim of this study is to determine whether reduced intensity behavioral weight loss treatment (rBWL) + Peer Health Coaches yields significantly greater weight loss than rBWL + Mentor Health Coaches and rBWL alone.
Interventions
BEHAVIORALReduced Intensity Behavioral Weight Loss + Peer Health Coach
Participants will receive a 12-month reduced intensity group behavioral weight loss program. During weeks that there are no group meetings, participants will be coached by peers (i.e., other members of their weight loss group).
BEHAVIORALReduced Intensity Behavioral Weight Loss + Mentor Health Coach
Participants will receive a 12-month reduced intensity group behavioral weight loss program. During weeks that there are no group meetings, participants will be coached by a mentor (i.e., successful weight loser).
BEHAVIORALReduced Intensity Behavioral Weight Loss
Participants will receive 12 months of a reduced intensity group behavioral weight loss program.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Weight change from the initial assessment to the 12-month assessment measured on a digital scale to the nearest 0.1-kilogram | baseline to 12 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Direction of social comparison between participants and their Peer or Mentor weight loss coach | 2-weeks, 3-months, 6-months, 9-months, and 12-months | Participants in rBWL + Peer and rBWL + Mentor will complete a questionnaire that assesses whether their progress on weight loss, diet, and activity are worse, similar to, or better than their coach's on a 5-point likert scale. Mean scores on this measure will be reported. |
