Study Description

Brief Summary:

Experimental studies of the experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis, indicate that the number of calories fed to mice prevent EAE and are also associated with less severe disease in mice who do develop the disease. Currently, whether these results translate favorably in humans is unknown. This is a pilot trial of testing two caloric restriction (CR) diets versus a control diet in multiple sclerosis (MS) patients: one continuous caloric restriction (CR) diet where a small number of calories will be restricted every day or another intermittent CR diet where a caloric intake will be restricted more severely 2 days per week. Participants are randomized to one of the diets, and for the first 8 weeks, will receive standardized, prepared meals tailored to the specific diet. At the conclusion of the controlled feeding study, all participants will transition to an unblinded phase for an additional 40 weeks where they are provided with instructions to follow an intermittent CR diet.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Continuous calorie restriction; Participants will be provided with a diet that includes approximately 78% of calories each day that would be needed to maintain current BMI.	Other: Diet; Diet, standardized to the 50th percentile for macronutrients, will be provided at varied calorie levels as described.
Experimental: Intermittent calorie restriction; Participants will be provided a diet that with a daily calorie intake required to maintain current BMI, except only 25% of this calorie intake will be provided for 2 days a week.	Other: Diet; Diet, standardized to the 50th percentile for macronutrients, will be provided at varied calorie levels as described.
Placebo Comparator: Control calorie intake; Participants will be assigned to consume enough calories each day required to maintain current BMI	Other: Diet; Diet, standardized to the 50th percentile for macronutrients, will be provided at varied calorie levels as described.

Outcome Measures

Primary Outcome Measures :

1. Adverse events [ Time Frame: 8 weeks ]
   Adverse events will be categorized by organ system and by the blinded neurologist's assessment of the relation to the diet.

Secondary Outcome Measures :

1. Adherence to Calories Assigned [ Time Frame: 8 weeks ]
   Adherence will be assessed by comparing the total caloric intake provided to the patients through the assigned diet to the total energy intake determined by the research dieticians.
2. Adherence to Calories Assigned [ Time Frame: 48 weeks ]
   Adherence during the "advice-only" phase will be compared to adherence in each diet group during the first 8 weeks using paired t-tests, where the grouping is done naturally by subject.
3. Adverse Events [ Time Frame: 48 weeks ]
   Adverse events will be categorized by organ system and by the blinded neurologist's assessment of the relation to the diet.
4. Quality of Life Questionnaire [ Time Frame: 48 weeks ]
   "Functional Assessment in MS" results will be assessed during the study
5. NIH Patient-Reported-Outcomes Measurement Information System (PROMIS )Fatigue Questionnaire [ Time Frame: 48 weeks ]
   PROMIS Fatigue results will be assessed during the study
6. Change in metabolite ratios [ Time Frame: 8 weeks ]
   The impact of each calorie restriction diet versus control diet on the metabolomics profile will be assessed.
7. Immune cell subsets/cytokines [ Time Frame: 8 weeks ]
   The impact of each calorie restriction diet versus control diet on ratios of immune cell subsets (e.g. T-helper (TH)17, TH1, TH2, T regulatory) and related cytokines will be assessed.
8. Change in concentration of measures of metabolism [ Time Frame: 8 weeks ]
   The impact of each calorie restriction diet versus control diet on fasting glucose, insulin, leptin, ghrelin, C-reactive protein, lipids, and long-chain ceramides will be assessed.
9. Change in serum lipid concentration [ Time Frame: 8 weeks ]
   The impact of each calorie restriction diet versus control diet on fasting lipids and long-chain ceramides will be assessed.
10. Change in serum brain-derived neurotrophic factor concentration (BDNF) [ Time Frame: 8 weeks ]
    The impact of each calorie restriction diet versus control diet on fasting BDNF will be assessed.
11. Change in levels of oxidative stress biomarkers [ Time Frame: 8 weeks ]
    The impact of each calorie restriction diet versus control diet on protein carbonyls, 8-isoprostane, nitrotyrosine, and 4-hydroxynonenal adducts will be assessed.
