Inclusion criteria

  • Body Mass Index between 30 and 40
  • Age between 40 and 60 years
  • English speaking

Exclusion criteria

  • Are unwilling to communicate regularly with a weight loss coach
  • Report not being able to walk 2 blocks (1/4 mile) without stopping
  • Are currently participating in a weight loss program, taking a weight loss medication, have a history of bariatric surgery, or lost ≥ 5% of body weight during the past 6-months
  • Are pregnant, lactating, less than 6-months post-partum, or plan to become pregnant during the intervention timeframe
  • Report a heart condition, chest pain during periods of rest or activity, or loss of consciousness on the Physical Activity Readiness Questionnaire
  • Report a medical condition that would jeopardize their safety if involved in a weight management program with diet and exercise guidelines
  • Report conditions that, in the judgment of the PI, would render the participant unlikely to follow the study protocol (e.g., relocation, dementia, terminal illness, substance abuse).

Treatment and study plan

Reduced Intensity Behavioral Weight Loss + Peer Health Coach

Behavioral

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).

Reduced Intensity Behavioral Weight Loss + Mentor Health Coach

Behavioral

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).

Reduced Intensity Behavioral Weight Loss

Behavioral

Participants will receive 12 months of a reduced intensity group behavioral weight loss program.

Primary outcomes

  1. Weight change from the initial assessment to the 12-month assessment measured on a digital scale to the nearest 0.1-kilogram

    Time frame: baseline to 12 months

Secondary outcomes

  1. Direction of social comparison between participants and their Peer or Mentor weight loss coach

    Time frame: 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.
