Summary

This study tests whether a stepped-care program using digital tools like smart scales, activity trackers, and text messages, plus in-person counseling if needed, can help adults with obesity maintain at least 5% weight loss for a year. About 258 participants first lose weight through a 16-week program with group counseling and meal replacements. Those who succeed are then randomly assigned to usual care, self-monitoring with digital tools, or the stepped-care program. The goal is to find a practical way to prevent weight regain.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
behavioral intervention (digital health tools, counseling, and meal replacement diet)
What this could lead to
If successful, this could provide an effective, scalable strategy to help people keep weight off long-term after losing it.
What could go wrong
This is a relatively small, early-stage trial focused on maintenance, not weight loss itself. Results may not apply to everyone, and some participants may still regain weight.
