ReLearn Trial Summary

This trial is testing a weight-loss AI system to see if it's more effective and cheaper than weekly gold-standard behavioral weight-loss treatment.

Who is the study for?
Adults aged 18-70 with a BMI of 27-50 kg/m², able to walk two city blocks and engage in remote weight loss programs using a smartphone. Excludes those with certain medical conditions, recent significant weight loss, or changes in medications affecting weight.Check my eligibility
What is being tested?
Project ReLearn is comparing standard behavioral treatment for weight loss against an AI-optimized version that adapts weekly based on participant responses using mobile and wearable tech over one year.See study design
What are the potential side effects?
Since this trial involves non-medical interventions focused on behavior change and monitoring via technology, there are no direct side effects like you'd expect from medication; however, participants may experience stress or fatigue.

ReLearn Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: BWL-AIExperimental Treatment1 Intervention
1 year of remote weight loss treatment made up of a combination of (1) remote small group-based behavioral weight loss sessions, (2) 12-minute individual video calls, (2) automated text messages. An MS-level clinician will deliver the group treatment. Most video calls will be delivered by a paraprofessional coach, but some by an MS-level clinician. Each week the AI system will select one of the interventions for each participant based on which treatment the participant has responded to the best, within certain time constraints.
Group II: BWL-SActive Control1 Intervention
1 year of remote gold standard, small group-based behavioral weight loss treatment with an MS-level clinician.
