Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-70 with mild to moderate ulcerative colitis as indicated by a partial Mayo score between 2 and 7.

Probably not a fit

Patients who are pregnant, nursing, or have serious medical conditions that could complicate dietary changes may not benefit from this study.

What this trial studies

This study investigates how a fasting mimicking diet (FMD) influences inflammation in patients with mild to moderate ulcerative colitis. Participants will follow a diet that allows them to experience the benefits of fasting while consuming food deemed safe by the FDA. The research aims to assess changes in inflammation markers and quality of life after three cycles of a five-day FMD. This approach is novel as dietary interventions for ulcerative colitis have been limited in previous research.

Why it matters

Potential benefit: If successful, this diet could provide a new dietary management strategy for patients with ulcerative colitis, potentially reducing inflammation and improving quality of life.

How similar studies have gone: While dietary interventions for ulcerative colitis are limited, fasting mimicking diets have shown promise in other studies, suggesting potential for success in this approach.
