Summary

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.

Conditions

• Weight Loss

Interventions

Type	Name	Description
BEHAVIORAL	Standard Behavioral Weight Loss Treatment	Behavioral weight loss treatment is the current gold standard treatment for obesity.
BEHAVIORAL	AI-optimized Behavioral Weight Loss Treatment	AI-optimized Behavioral Weight Loss Treatment will continuously vary intensity (automated text message, videoconference group, individual coaching call) and coach type (paraprofessional or MS-level expert) based on continuously-monitored participant digital data.
