NCT ID NCT07557979

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study will compare weight-loss plans made by ChatGPT with those made by a human dietitian. 21 adults with obesity will be split into three groups: one gets AI-only advice, one gets a dietitian's plan, and one gets a combination of both. The goal is to see which approach leads to better weight loss and health improvements.
