GLP-1 Users' diets under the microscope: what are they really eating?
NCT ID NCT07313384
First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This study follows 50 adults who are about to start GLP-1 therapy for obesity or type 2 diabetes. Researchers will track how their eating habits change over 12 weeks using diet quality scores and body weight. The goal is to understand what dietary support people need while on these medications, since current guidance focuses mostly on cutting calories rather than ensuring good nutrition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GLP-1 therapy (a class of medications for obesity or type 2 diabetes)
- What this could lead to
- If successful, this study could help develop better dietary guidelines and support programs for people taking GLP-1 medications.
- What could go wrong
- This is a small observational study (50 people) that does not test a new treatment. It only looks at eating habits, so it cannot prove whether any diet changes improve health outcomes.
