Key finding
Self-reported body weight was lower than the weight measured in the clinic after 6 months by 1.03 kg (95% CI 1.01-1.05; P <.001).
This study validated self-reported weight from mobile health applications in weight loss interventions, showing significant discrepancies between self-reported and clinic-measured weights.

Study focus
This study validated self-reported weight from mobile health applications in weight loss interventions, showing significant discrepancies between self-reported and clinic-measured weights.
This study highlights the potential of mobile health applications in weight management, suggesting that self-reported data can be a practical alternative to clinic measurements. This is particularly important for remote monitoring and interventions, as it allows for greater flexibility and accessibility for patients. Understanding the accuracy of self-reported weights can enhance the effectiveness of digital health strategies in promoting weight loss.
Single-arm study limits generalizability. Potential bias in self-reported data. Lack of diverse population representation.
