Summary

This study investigates how easy or hard it is for adults with inflammatory bowel disease (IBD) to follow three different eating plans: intermittent fasting, the Mediterranean diet, and the low FODMAP diet. Researchers will interview participants to understand what helps or hinders sticking to these diets, and whether certain diets improve symptoms. The goal is to find practical ways to make dietary changes more manageable for people with IBD.

What this could mean

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

Active substance: dietary interventions: intermittent fasting, Mediterranean diet, and low FODMAP diet
What this could lead to: If successful, this could identify which diet is easiest for people with IBD to stick with and most effective for symptom relief, potentially improving quality of life.
What could go wrong: This is a small, early-stage study (45 participants) focused on barriers and adherence, not on proving which diet works best. Results may not apply to all IBD patients.
