Trial ID: NCT04147585


The purpose of this study is to see how an Intermittent Calorie Reduced Diet (IRCD) that mimics fasting effects inflammation in patients with mild to moderate Crohn's disease (CD). The diet may allow users to receive the benefits of fasting while also being able to enjoy food (the ingredients of which are GRAS (generally recognized as safe) by the Food and Drug Administration (FDA). Research on dietary interventions and CD are very limited. Diets that mimick fasting have been studied with support of the National Institute of Health and published in leading journals. This research investigates whether markers of inflammation decrease and/or quality of life increases after five-day periods of the IRCD, and may provide rationale for its use to treat CD.
