NCT05231824Completed
Using Artificial Intelligence to Optimize Delivery of Weight Loss Treatment
Source: ClinicalTrials.gov · Last updated 4 Sept 2026
Brief summary (registry, in English)
Project ReLearn is testing the efficacy and cost-effectiveness of an Artificial Intelligence system for optimizing weight loss coaching. Participants are randomized to a 1-year weekly gold standard behavioral weight loss remote (video) group treatment or the AI-optimized treatment, which is made up of a combination of remote group treatment, short video call and automated message. In the AI-optimized condition, the system monitors outcomes (via wireless scale, mobile phone app, and wristworn tracker) and, each week, assigns each participant the treatments they have responding to the best, within certain time constraints.
