About

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.

Full 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.

100 participants in 2 patient groups

Low Glycemic Load
Experimental group
Description:
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.
Treatment:
Behavioral: Behavioral support
Behavioral: Calorie restriction
Behavioral: Glycemic load
Standard Glycemic Load
Active Comparator group
Description:
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.
Treatment:
Behavioral: Behavioral support
Behavioral: Calorie restriction
Behavioral: Glycemic load
