Can setting easier goals boost digital weight loss success?
NCT ID NCT05715242
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This pilot trial tests whether easier or harder daily goals in a digital weight loss program are more feasible and acceptable for adults with overweight or obesity. Participants receive a 10-week remote program with self-monitoring tools and are assigned different goal intensities for calories, steps, eating window, and certain foods. The study aims to see which goal levels keep people engaged and satisfied, paving the way for more effective digital weight loss interventions.
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 with varying goal intensities (calorie, step, eating window, red zone food)
- What this could lead to
- If successful, this could help design more effective digital weight loss programs by identifying the optimal goal intensity for engagement and weight loss.
- What could go wrong
- This is a small pilot study focused on feasibility, not effectiveness. Results may not generalize, and the intervention's impact on weight loss is not yet established.
