The purpose of this study is to evaluate if following a specific low fat diet will improve the brain damage as seen by Magnetic Resonance Imaging (MRI) and to decrease the progression of multiple sclerosis (MS) as evidenced by clinical evaluation and symptoms.

Primary Outcome Measures:
  • Number of new MS T2 lesion formation on brain MRI in those randomized to the low fat study diet with that of subjects randomized to follow their regular diet. [ Time Frame: Baseline. Month 12. ]

Secondary Outcome Measures:
  • To assess effects of the low fat study diet on clinical activity of MS as by relapse rate and disability progression and on fatigue, depression and quality of life. [ Time Frame: Baseline. Month 3. Month 6. Month 9. Month 12. ]
  • To study the effects of the Low Fat Study Diet on serum markers of inflammation [ Time Frame: Baseline. Month 6. Month 12. ]
  • To assess safety and tolerability of the low fat study diet upon 12 months of administration [ Time Frame: Baseline. Month 3. Month 6. Month 9. Month 12. ]

Enrollment: 61
Study Start Date: February 2009
Study Completion Date: July 2014
Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1. Low fat study diet
The low fat study diet arm will receive low fat diet training and followed for 12 months on the diet.
Other: Low fat study diet
The low fat study diet is a very low-saturated-fat, plant food based diet. It will be approximately 10% fat, 14% protein and 76% carbohydrate.The diet is is starched based and also contains fresh or frozen fruits and vegetables and there is no animal meat used, including no use of fish. This diet is very low in saturated fats and enriched in unsaturated fats. Subjects do not take dietary supplements.
No Intervention: 2. Regular diet group
The regular diet arm will be a wait-listed group that will receive no training in diet and will be advised to continue their regular (usual) diet as was prior to entry into the study, for the duration of the study. They will have a similar clinic follow up schedule as the treatment group. The regular diet group will be given identical instructions to exercise regularly similar to the treatment group.

Detailed Description:
This research project has significance for its potential to develop a new therapeutic approach to MS. Current treatments in MS include disease modifying therapies such as human recombinant interferon beta, glatiramer acetate and natalizumab. However, these are only partially effective, cannot be taken orally, have side-effects and are very expensive. Developing treatment that can be combined with current disease modifying agent remains an important goal for improving the care of people with MS.

Inclusion Criteria:

  • Clinical diagnosis of the relapsing-remitting form of MS
  • Age 18-70, inclusive
