First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
behavioral weight loss intervention via smartphone app
What this could lead to
If successful, this could offer a more accessible and cost-effective way to manage obesity without in-person visits.
What could go wrong
This is a behavioral intervention, not a drug, so results depend on participant adherence. The study is not yet complete, and the app may not work for everyone.
