Calorie Restriction in Multiple Sclerosis Patients

"Calorie restriction will be achieved by alternate day fasting. During the day of fasting the subject will be allowed to eat two salads with light dressing, not to go over approximately 500 calories. The CR group subjects will fast on day 2 (second day of steroids) and then continue to fast on alternate days until day 15. This is the end of the Acute CR phase of the Study, and patients may discontinue the study at this point.~Chronic CR phase At the end of the Acute CR phase, both groups will be offered to enroll in the alternate day fasting regimen for 6 months (Chronic CR phase). During this phase, patients with a BMI \<28 will follow a regimen of fasting for two days per week while patients with BMI\>28 will follow a regimen of fasting for three days per week."
