Details and patient eligibility


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.

Full 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.

Trial design

Primary purpose




Interventional model

Parallel Assignment


None (Open label)

61 participants in 2 patient groups

1. Low fat study diet
Experimental group
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
2. Regular diet group
No Intervention 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.
