About

This is a randomized controlled trial that will test the effects of intermittent fasting (IF) in subjects with relapsing-remitting MS (RRMS). The goal of this clinical trial is to acquire objective evidence regarding whether an IF diet has beneficial effects in MS patients.Two dietary regimens, IF and western diet, will be compared in a randomized, controlled, single-blinded 12 week trial in RRMS patients. This is a single-center study.

Full description

RRMS patients will be enrolled in a randomized, controlled, single-blinded 12 week trial in which IF will be compared to a standard western diet. Patients will be recruited at the John L. Trotter MS center and randomly assigned to either a standard western diet or an IF diet (1:1). Enrolled subjects will complete a clinical and laboratory assessment before starting the diet (baseline), at week 6 and at end of the study (week 12). The primary outcome will be leptin at week 12 measured in the peripheral blood. Secondary outcomes will be: 1) peripheral blood metabolic profiling; 2) anthropometric (body mass index and waist circumference) and total body fat measures; 3) gut microbiota richness and composition.

61 participants in 2 patient groups

Intermittent fasting

Experimental group

Description:

The subjects randomized to this group will do IF by restricting their diet and consuming few calories two days per week. During the days of fasting, subjects will be allowed to drink water, calorie-free beverages, and eat fresh, steamed or roasted non-starchy vegetables.

Treatment:

Other: Intermittent fasting

Western diet

No Intervention group

Description:

The subjects randomized to this group will eat a standard western style diet.
