Can a mediterranean diet and Time-Restricted eating tame gut inflammation?
NCT ID NCT07752446
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether a 12-week dietary intervention can improve gut health, reduce inflammation, and enhance quality of life in adults with ulcerative colitis who are in remission. Participants are randomly assigned to a Mediterranean diet, a Mediterranean diet combined with time-restricted eating (eating within an 8-hour window), or standard dietary advice. The study measures changes in stool markers of gut health, inflammation, and symptoms to see if these eating patterns offer benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mediterranean diet and time-restricted feeding (behavioral intervention)
- What this could lead to
- If effective, this dietary approach could offer a non-drug way to support gut health and reduce inflammation in people with ulcerative colitis in remission.
- What could go wrong
- This is a small pilot study, so results may not be conclusive or generalizable. Dietary changes can be hard to maintain, and the benefits are uncertain.
