Healthy Eating and Active Living for People Living With Multiple Sclerosis (HEAL MS): A Lifestyle Program for People With Multiple Sclerosis

The goal of this clinical trial is to learn whether a structured lifestyle program can improve health and wellbeing in people living with multiple sclerosis (MS). The program focuses on four areas: nutrition, physical activity, sleep, and stress management. The study will also examine how lifestyle changes affect biological markers related to inflammation, metabolism, and immune function. The main questions the study aims to answer are: Can a 12-week lifestyle program improve fatigue, physical function, sleep, and quality of life in people with MS? Do lifestyle changes influence biological markers related to inflammation, metabolism, and mitochondrial function? Participants will first complete a 12-week observation period to measure their usual lifestyle and health. After this, they will take part in the 12-week HEAL MS lifestyle program. Participants will: Attend four assessment visits at Yas Clinic (baseline, before the intervention, after the intervention, and three months later) Participate in two supervised online exercise sessions per week during the 12-week program Follow a structured nutrition plan, with meals provided during the first two weeks Use a mobile application to log daily habits related to exercise, nutrition, sleep, and stress Complete questionnaires and physical tests and provide blood, saliva, and stool samples during assessment visits Researchers will analyze these data to understand whether lifestyle interventions can support symptom management and overall health in people living with MS.
