Adherence
A mobile app-based behavioral weight loss intervention delivered exclusively via smartphone without human coaching does not produce significant weight loss compared to a control group in young adults over 24 months.
Relying solely on a weight loss app is unlikely to result in significant weight loss for young adults. While apps can help with self-monitoring, they lack the human interaction and accountability that are critical for sustained behavioral change. To lose weight, you likely need a combination of technology and personal coaching or social support.
CP did not lead to weight loss, and PC did not lead to sustained weight loss relative to Control.
Why this rating
Randomized, controlled trial with 365 participants, high retention (86%), and long duration (24 months).
