Trial Summary

What is the purpose of this trial?

Inflammatory bowel disease (IBD) is a chronic illness characterized by inflammation of the intestine. Many individuals with IBD suffer from depressive symptoms and anxiety which can lead to a decreased quality of life, poor treatment compliance, and higher morbidity and mortality. The object of this clinical trial is to investigate the effects of a fasting mimicking diet in IBD patients who are suffering with symptoms of depression. Participants will carry out 3 cycles of a 5-day period of a plant-based low caloric diet or a plant-based caloric sufficient diet following by 3 weeks of eating normally. Effects of the dietary intervention on microbes in the gut, immune and metabolic function, and depressive symptoms will be measured. The overall goal is to develop a safe and effective treatment to improve mental health in patients with IBD by targeting the gut microbiome through dietary interventions.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the fasting-mimicking diet treatment for inflammatory bowel disease-related depression?

Research suggests that a plant-based diet may help reduce inflammation in inflammatory bowel disease (IBD) patients, which could potentially improve symptoms. Additionally, a plant-based diet has been shown to induce remission in some cases of mild ulcerative colitis, a type of IBD.12345

How is the fasting-mimicking diet treatment different from other treatments for inflammatory bowel disease-related depression?

The fasting-mimicking diet is unique because it involves a plant-based, low-calorie approach that mimics the effects of fasting, potentially offering benefits for inflammatory bowel disease-related depression by altering gut microbiota and reducing inflammation, unlike traditional diets that may not have these specific effects.16789

Treatment Details

Interventions

  • Plant-based fasting-mimicking diet (Other)
Trial OverviewThe study tests the effects of a fasting-mimicking diet on depressive symptoms in IBD patients. Participants will alternate between a low-calorie plant-based diet for 5 days and their normal diet for 3 weeks over several cycles. The focus is on how this diet affects gut microbes and mental health.

Findings from Research

In a study of 434 patients with inflammatory bowel disease (IBD), about 36.6% totally excluded at least one food category, and 62.4% partially excluded foods, indicating a significant prevalence of exclusion diets among these patients.
Approximately 30.8% of patients reported some form of fasting, with disease activity and specific treatments being linked to both exclusion diets and fasting behaviors, suggesting that dietary management could play a crucial role in their clinical care.

A plant-based diet may help reduce inflammation and improve the gut microbiome in patients with Inflammatory Bowel Disease (IBD), potentially enhancing their quality of life.
Current evidence suggests that a Westernized diet is linked to increased risk and relapse of IBD, highlighting the need for more rigorous studies to confirm the benefits of dietary modifications in managing this condition.
The role of a plant-based diet in the pathogenesis, etiology and management of the inflammatory bowel diseases.Grosse, CSJ., Christophersen, CT., Devine, A., et al.[2021]
A plant-based diet (PBD) was effective in inducing remission in a 34-year-old woman with mild ulcerative colitis, as her stool normalized and inflammatory markers improved during a 19-day educational hospitalization.
When the PBD alone was insufficient for sustained remission, medication (sulfasalazine) was introduced, leading to normal stool formation and confirmed endoscopic remission, highlighting a personalized approach to treatment.
