What is the purpose of this trial?

This trial examines how effectively a special anti-inflammatory eating plan can treat irritable bowel syndrome (IBS). Known as the Lifestyle Eating and Performance (LEAP) Program, the plan involves working with a dietitian to adjust one's diet. It targets individuals with IBS with diarrhea (IBS-D) who have experienced moderate symptoms for some time. Those with IBS-D who are ready to try a new diet plan for three months may find this trial suitable.

As an unphased trial, this study provides a unique opportunity to explore a dietary approach to managing IBS-D symptoms.

Will I have to stop taking my current medications?

The trial requires that you have been on a stable dose of your current medications for at least one month before joining. It does not specify that you need to stop taking them.

What prior data suggests that the LEAP Program is safe for individuals with Irritable Bowel Syndrome?

A previous study found the LEAP program suitable and well-tolerated by all participants. This program uses a personalized diet plan to help manage irritable bowel syndrome (IBS) symptoms. Participants reported no harmful side effects, indicating that no one experienced negative reactions from following the program. This suggests the LEAP program is safe for people with IBS. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Lifestyle Eating and Performance (LEAP) Program for irritable bowel syndrome (IBS) because it takes a personalized nutrition approach, which is different from the usual medications and dietary adjustments typically recommended for IBS. While standard treatments often involve medications to relieve symptoms or general dietary advice, the LEAP Program focuses on identifying and eliminating specific food sensitivities unique to each individual. This tailored approach aims to reduce IBS symptoms by directly addressing the underlying dietary triggers, offering a potentially more effective and sustainable way to manage the condition.

What evidence suggests that the LEAP Program is effective for irritable bowel syndrome?

Research has shown that the Lifestyle Eating and Performance (LEAP) Program can greatly help people with irritable bowel syndrome (IBS). One study found that IBS patients experienced fewer stomach problems and felt better overall after following the LEAP program. Another study suggested that these improvements might result from changes in diet-related inflammation. The LEAP program, which participants in this trial will follow, includes a personalized eating plan that reduces inflammation and has benefited people with moderate to severe IBS symptoms. Overall, these findings suggest the program may effectively manage IBS. ^{1 2 3 5 6}

Published Research Related to This Trial

Restricting dietary FODMAPs has been shown to improve symptoms like abdominal pain and bloating in over half of IBS patients, highlighting its efficacy as a treatment option.

There is potential for developing personalized dietary therapies based on individual sensitivities to FODMAPs, which could lead to more effective and less restrictive dietary plans for IBS patients.

The role of diet in the management of irritable bowel syndrome: a focus on FODMAPs. Dolan, R., Chey, WD., Eswaran, S.[2018]

Dietary interventions, particularly elimination diets, are commonly used to treat irritable bowel syndrome (IBS), but they may not be suitable for all patients, especially those with orthorexia nervosa or avoidant/restrictive food intake disorder.

Current dietary strategies should be personalized based on individual symptoms and biomarkers, as diet interventions are effective for only a subset of IBS patients, and there is growing interest in 'functional foods' as a complementary approach.

The low FODMAP diet has been shown to be effective in managing symptoms for a majority of patients with irritable bowel syndrome (IBS), based on recent studies.

While probiotics show promise in IBS treatment, their effectiveness varies by strain and dosage, indicating a need for further research to identify the most beneficial options.

Irritable bowel syndrome and diet: where are we in 2018? Dimidi, E., Rossi, M., Whelan, K.[2022]

A low FODMAP diet was reported to be effective by 86% of patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), with significant improvements in symptoms like bloating (82%) and abdominal pain (71%).

Patients on the low FODMAP diet experienced a notable reduction in chronic disease courses and an increase in normal stool frequency, indicating that this dietary approach can lead to better management of bowel symptoms in both IBS and IBD patients.

The LEAP program, guided by the Leukocyte Activation Assay-MRT, significantly improved IBS symptoms and quality of life in a retrospective study of 146 adults, with notable reductions in gastrointestinal symptoms (P < 0.001).

Participants, primarily female and followed for about 10 weeks, benefited from personalized dietary modifications, highlighting the importance of tailored dietary approaches in managing IBS effectively.

Is Personalized Dietary Therapy Effective for Individuals With Irritable Bowel Syndrome? Zarini, GG., McLean, MA., Delgado, SI.[2023]

A low FODMAP diet (LFD) was more effective than a standard diet in relieving symptoms of irritable bowel syndrome (IBS), particularly abdominal pain and diarrhea, in a study of 70 adults over four weeks.

Both diets improved quality of life, but the LFD group maintained symptom relief even after reintroducing FODMAPs, suggesting it may be a preferred dietary approach for individuals with IBS, especially those experiencing diarrhea.

The 5Ad Dietary Protocol was tested on 22 subjects with functional bowel disorders (FBDs) and resulted in significant improvements in all abdominal symptoms, indicating its efficacy in reducing gastrointestinal issues.

Improvements in stool consistency and frequency were observed regardless of factors like BMI, age, or prior IBS diagnosis, suggesting that the 5Ad Dietary Protocol could be a versatile treatment option for various forms of FBDs.
