Fasting diet shows promise for depression in bowel disease

NCT ID NCT05382897

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested whether a low-calorie, plant-based diet that mimics fasting could reduce depressive symptoms in people with inflammatory bowel disease (IBD). 42 adults with mild-to-moderate depression and IBD followed either the fasting-mimicking diet or a calorie-sufficient plant-based diet for three 5-day cycles over three months. Researchers measured changes in mood, gut microbes, and immune function to see if targeting the gut could improve mental health.

What this could lead to

If it works, this could offer a safe, non-drug way to improve mood in people with inflammatory bowel disease.
