Brief summary
A randomized, controlled pilot trial of a dietary intervention vs. wait-list control in patients with MS and fatigue for management of their fatigue. The hypothesis of this study is that participants following the low-fat study diet will demonstrate a significant reduction in fatigue after four months compared to wait list controls.

Eligibility
Inclusion criteria
For participants with MS: Inclusion Criteria: * Age 18-70 * Diagnosis of MS by 2010 McDonald Criteria * EDSS ≤ 7.5 * Experiencing moderate to severe fatigue (MFIS ≥ 38)
Exclusion criteria
* Current cardiopulmonary disease requiring treatment * Diabetes * Pregnancy or breast-feeding * MS exacerbation within 30 days of screening visit * IV steroids within 30 days of screening visit * Dietary fat content of \<30% as assessed by food frequency questionnaire (FFQ) at screening visit * Fish oil or flax seed oil supplementation within 30 days of screening visit
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fatigue | Baseline to month 4 | Measured by Modified Fatigue Impact Scale (MFIS). The MFIS is a 21-item questionnaire that assesses overall self-reported fatigue. Subjects rate agreement with a series of statements on a scale of 0 (rarely) to 4 (almost always), in context of their fatigue over the preceding four weeks. Total possible score of 84. Individuals with an MFIS score of \> 38 are considered to experience moderate to severe fatigue |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fatigue | Baseline to month 4 | Measured by Fatigue Severity Scale (FSS). The FSS is a 9-item questionnaire, with subjects giving a response from 1-7 to indicate their degree of agreement with each statement. |
| Disability | Baseline to month 4 | Measured by EDSS. The EDSS is an eight functional system scale including motor, sensory, cerebellar, brain stem, visual, mental, sphincteric, and other systems. Each functional system is graded from 0 (no disability) to 5 or 6 (maximal disability)20. An integrated score between 0 (normal examination) and 10 (death from MS) is formed based on the score in each functional system. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Microbiome- Relative abundance of targeted species of gut microflora | Baseline to month 4 | Measured by 16S rRNA sequencing |
