What the study is about

The goal of this clinical trial is to compare weight change and other related outcomes associated with three different behavioral weight loss interventions (STANDARD Behavioral, PREVENT, and PROMOTE) in adults with obesity. The main questions it aims to answer are:

  • Which of the three Internet-delivered weight loss programs results in the greatest weight loss?
  • How do key weight-related behaviors (e.g., adherence, diet, physical activity) differ across the arms?
  • What individual characteristics predict success in each arm?
  • What are the underlying mechanisms of each approach?
  • Are there any potential adverse outcomes associated with any of the conditions (e.g., depression, weight stigmatization, increased body image concerns).

Participants will

  • signed informed consent
  • complete a baseline assessment
  • be randomized to 12 months of either Standard iBWL, PREVENT or PROMOTE
  • complete a training workshop to learn arm-specific cognitive strategies
  • complete a 12-month Internet-delivered weight loss program, requiring self-monitoring of intake and exercise and viewing of 12 weekly lessons followed by 9 monthly lessons
  • complete an assessment at 3 months (during treatment)
  • complete a refresher workshop on arm-specific cognitive strategies at 3 months
  • complete an assessment at 6 months (during treatment), 12 months (at the conclusion of treatment), and 18 months (6 months after treatment

Being studied: Standard Behavioral Weight Loss Intervention; PREVENT Behavioral Weight Loss Intervention; PROMOTE Behavioral Weight Loss Intervention
