The Power of a 5-day Fasting-Mimicking Diet for Crohn’s Disease

Explore the efficacy of fasting-mimicking diet that helps reset the immune response in mild-to-moderate Crohn’s disease.

A five-day cycle of a calorie-restricted fasting-mimicking diet (FMD) can significantly reduce both physical symptoms and biological markers of gut inflammation, improve metabolic health, and help reset immune response in patients with mild-to-moderate Crohn’s disease.

The data was based on a randomized control trial from Stanford Medicine, published in Nature Medicine.

The study provides an evidence-based tool that help manage Crohn’s disease in patients through diet and nutrition. The findings pave the way for safe treatments in the future for Crohn’s disease.(1^✔ ✔Trusted Source

How a Fasting-Mimicking Diet Helps Guide Crohn’s Patients Toward Long-Term Remission

While dietary interventions are difficult to study — participants’ reports of what they’re eating aren’t always accurate, and the placebo effect can’t be avoided because participants know which diet they’re on — the findings were notable, demonstrating significant declines in objective markers of inflammation in biologic samples alongside improvements in clinical symptoms.

The study may help physicians guide patients in finding a diet that alleviates symptoms.

“We have been very limited in what kind of dietary information we can provide patients,” said Sidhartha R. Sinha, MD, an assistant professor of gastroenterology and hepatology and the senior author on the paper. “This study will give physicians evidence to support recommendations in an area that patients are very curious about.”

Patients with Mild-to-Moderate Crohn’s Disease Need Diet Options Beyond Steroid Therapy

A chronic condition affecting about a million Americans, Crohn’s disease causes inflammation in the digestive tract, leading to symptoms of diarrhea, cramping, abdominal pain and weight loss. Steroids are the only approved therapeutic for mild Crohn’s, but their use is limited due to significant side effects, particularly with long-term use.

The study compared the symptoms and biological indicators of patients with mild-to-moderate Crohn’s disease as they either followed a fasting mimicking diet or ate their normal diet for three consecutive months. The study enrolled 97 patients across the country, with 65 in the fasting mimicking group and 32 in the control group.

Participants in the fasting mimicking group severely limited their calories for five consecutive days per month, eating between about 700 and 1,100 calories a day, Sinha said. Plant-based meals were provided during the fasting period. For the remainder of the month, the fasting mimicking group ate their normal diet.

How a Single Fasting-Mimicking Diet Cycle Can Improve Crohn’s Disease Symptoms

At the end of the study, about two-thirds of the fasting mimicking group experienced improvement in their symptoms. “We were very pleasantly surprised that the majority of patients seemed to benefit from this diet,” Sinha said.

“We noticed that even after just one FMD cycle, there were clinical benefits.”

In the control group, less than half experienced improvements in their symptoms. The improvement was likely a result of natural symptom fluctuations in Crohn’s disease and because patients continued to follow their standard care regimens, such as taking medications.

“Some participants in the fasting mimicking group experienced fatigue and headache,” Sinha said, but no serious side effects were reported.

Sinha was inspired to study the fasting mimicking diet in patients with Crohn’s disease after earlier research indicated the diet could reduce levels of C-reactive protein, a common marker of systemic inflammation in patients who had high baseline C-reactive protein levels.

“The effects seen on inflammatory markers made this an appealing diet to study in Crohn’s disease since many patients with this disease also have elevated inflammatory markers,” he said.

Targeted Fasting-Diet Cycle Could Help Lower Gut Inflammation in Crohn’s Disease

Along with tracking participants’ clinical response and remission, the researchers also explored changes in biological specimens, such as shifts in common markers of inflammation in both stool and blood.

“Our goal in collecting these and other biospecimens was to dig deeper into why there’s this differential response,” Sinha said. “Can we find mechanisms to explain the findings and signatures that might help predict patients who will respond to the diet?”

The researchers found a significant decline in fecal calprotectin, a protein in the stool that indicates gut inflammation, in the fasting mimicking group compared with the control group. Some inflammation-promoting lipid mediators derived from fatty acids also declined in fasting mimicking group participants.

Similarly, the immune cells of fasting mimicking group participants produced fewer of several types of inflammatory molecules. The researchers are now exploring whether changes in the gut microbiome may also help explain some of the benefits of the fasting mimicking diet.

“There’s still a lot more to be done to understand the biology behind how this and other diets work in patients with Crohn’s disease,” Sinha said.
