Functional Outcomes From Diets in Multiple Sclerosis
Purpose
The purpose of this study is to test the effects of two dietary interventions, glycemic load and calorie restriction, on physical function, cognition, pain, fatigue, mood, and anxiety in adults with multiple sclerosis (MS). The investigators will also explore the how the diet interventions impact inflammation, immunity, and metabolic biomarkers.

- Intervention Model Description
- Participants will be randomized to follow either a low GL or standard GL diet for 32 weeks. For the first 16 weeks, both groups will eat enough calories to maintain baseline weight. During the second 16 weeks, both groups will reduce calorie intake by 500 kcal/day,

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Low Glycemic Load |
This group will be prescribed a daily GL of <45 points/1000 kcal and 25% of daily calorie intake from carbohydrates. This group will be provided few processed foods. During the first 16 weeks, this group will eat enough calories to maintain baseline weight, and will reduce daily calorie intake by 500 kcal/day in the second 16 weeks. |
|
|
Active Comparator Standard Glycemic Load |
This group will be prescribed a daily GL of >75 points/1000kcal and 60% of daily calorie intake from carbohydrates. This group will be provided more processed foods than the low GL group. During the first 16 weeks, this group will eat enough calories to maintain baseline weight, and will reduce daily calorie intake by 500 kcal/day in the second 16 weeks. |

Detailed Description
100 participants will be randomized 1:1 to follow either a low glycemic load (GL) or standard GL diet for 32 weeks. For the first 16 weeks, all participants will eat enough calories to maintain their baseline weight. During the second 16 weeks, all participants will reduce calorie intake by 500kcal/day, with a goal of losing 5-10% of initial body weight. Participants will complete data collection at baseline (prior to randomization), at 17 weeks (after the weight stable phase) and again after completing the calorie restriction phase. All participants will receive meal plans and groceries for the duration of the trial.
