Efficacy of an app-based multimodal lifestyle intervention on body weight in persons with obesity: results from a randomized controlled trial
Authors' conclusion
Application of a multimodal app-based weight loss program results in moderate weight loss in persons with obesity.

- Participants
- 168 adults
- Comparison
- App-based multimodal weight loss program from baseline (ADHOC) vs after 12 weeks of waiting (EXPECT)
