NCT ID NCT04784585
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a smartphone app that monitors when you might be about to break your diet and sends helpful alerts or tips. About 200 adults with obesity and heart risk factors will use the app alongside a standard online weight loss program. The goal is to see which types of alerts work best to prevent dietary lapses.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
smartphone-based just-in-time adaptive intervention (JITAI) with behavioral education and self-efficacy training
What this could lead to
If it works, this could lead to a scalable smartphone tool that helps people stay on track with their diet during weight loss programs, improving long-term weight control.
What could go wrong
This is an early-stage optimization trial, not a test of weight loss itself. The interventions may not prevent lapses in real-world settings, and results may not apply to everyone.
