GLP-1 diet study: what happens when you eat on ozempic?
NCT ID NCT07001553
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at how people change their eating habits after starting GLP-1 drugs like Ozempic or Mounjaro for weight or diabetes. Researchers tracked 37 adults using dietary records and questionnaires to see if it's feasible to study diet changes this way. The goal was to understand recruitment and retention, not to test the drugs themselves.

- Active substance
- GLP-1 agonist (e.g., Ozempic, Trulicity, Mounjaro, Saxenda)
- What this could lead to
- If successful, this could help doctors understand how diet changes with these medications, leading to better dietary advice for patients.
- What could go wrong
- This is a small, completed feasibility study with only 37 participants, so results may not apply broadly. It only observed dietary patterns, not treatment effectiveness.
