Summary

This pilot study tests a smartphone app called BrainWeighve that helps teens aged 14-21 with obesity lose weight by replacing overeating with healthier coping behaviors. The study enrolls 38 participants to test the app's feasibility and satisfaction over 4 months. It is an early-stage trial focused on engagement and usability, not yet on proving weight loss.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
BrainWeighve smartphone app (behavioral intervention)
What this could lead to
If it works, this could point toward a convenient, app-based tool to help teens manage weight and reduce overeating.
What could go wrong
This is a very small pilot study (38 teens) testing feasibility, not effectiveness. The app may not lead to significant weight loss or may not engage users long-term.
