Summary
This study tests a smartphone-based weight loss program (EVO) against the standard Diabetes Prevention Program (DPP) in 524 adults with obesity. Participants use an app to track diet, activity, and weight, with remote coaching. The goal is to see which approach leads to more weight loss and is more cost-effective.
