Summary

This study tests a smartphone app called NutriTrack that uses artificial intelligence to help people with obesity or overweight track what they eat and how they feel. About 50 adults will use the app for 4 weeks. The main goal is to see if the app is easy to use and helpful for both patients and doctors.

What this could mean

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

Active substance
NutriTrack digital health application
What this could lead to
If successful, this could show that an AI app helps patients and doctors track eating habits and behaviors more easily, potentially improving obesity management.
What could go wrong
This is a small, early pilot study with only 50 participants over 4 weeks. The app may not be accurate or easy to use, and results may not apply to all patients.
