Can a cheaper, step-by-step weight loss plan beat the gold standard?
NCT ID NCT05861973
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares three weight loss approaches in 492 adults with obesity: a new stepped-care program that starts with minimal support and adds help only if needed, the standard Diabetes Prevention Program, and a self-guided option. The goal is to see if the smarter program can achieve similar weight loss at a lower cost. Participants must own a smartphone and not be in another weight loss program.
