TRF-CD: The Impact of Time Restricted Feeding in Crohn's Disease
Study Details
Study Description
Brief Summary
Time-restricted feeding (TRF) is a dietary regimen involving the consumption of food and liquids within a defined time window with or without additional restriction on dietary composition. TRF has been associated with improvements in inflammation, host metabolism, autophagy, gut microbial composition, and gut permeability. Crohn's disease is an inflammatory bowel disease of unknown etiology that likely results from a combination of genetic and environmental factors. This proposed study will test the hypothesis that a time-restricted feeding regimen will improve clinical outcomes and favorably influence the gut microbiome in patients with active Crohn's disease. If time-restricted fasting proves beneficial to this patient population then it will pave the way for larger, prospective studies and clinical trials.

|---|---|
| Experimental: Time Restricted Feeding Subjects will be required to fast for 16 consecutive hours daily for 4 weeks. The registered dietitian will provide subjects counseling on the intermittent fasting regimen. |
Other: Time Restricted Feeding
The counseling on the regimen will involve instructing the subjects on study compliance and fasting times. Subjects will be instructed to choose an eight-hour eating window (e.g., 11:00am - 7:00pm) during which the patient will be able to eat his/her normal diet. During the 16-hour fasting window (e.g., 7:00pm - 11:00am), the participant will be able to drink regular water and black coffee.

Outcome Measures
Primary Outcome Measures
- Change in patient reported outcomes as measured by Patient Recorded Outcome 2 (PRO2) scores. [Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet]
This will be measured to assess clinical response as determined by a reduction of either 8 or more points or a total PRO2 score of less than or equal to 8 points. The PRO2 score scale ranges from a score of 0 as the minimum and has no maximum limit. A score below 8 is considered remission; a score less than 14 is considered mild; and a score greater than 34 is considered severe.
- Change in Inflammatory Markers as measured by blood C-reactive protein (CRP). [Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet]
This will be measured to assess clinical response as determined by a reduction of 50% or more from baseline or normalization of the CRP level results.
- Change in inflammatory markers as measured by fecal calprotectin lab results [Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet]
This will be measured to assess clinical changes as determined by a reduction of 50% or more from baseline or normalization of the calprotectin levels results.
Secondary Outcome Measures
- Change in taxonomic composition of the gut microbiome as measured by Polymerase Chain Reaction (PCR) analysis. [Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet]
This will be measured to assess the impact of time restricted feeding on intestinal microbiota composition.
- Markers of systemic peripheral blood immunity as measured by Mass Cytometry by Time-Of-Flight (CyTOF) analysis. [Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet]
This will be measured to assess the effect of time restricted feeding on immune cell composition.
