Food as Medicine for ALS, Muscular Dystrophy and Other Neuromuscular Disorders

Nutrition doesn’t look the same for every neuromuscular disease, and that’s exactly the point, according to Rabia Malik, M.D., director of the MDA Care Center at Rush University Medical Center. Patients with amyotrophic lateral sclerosis (ALS) often face rapid, unexpected weight loss driven partly by a hypermetabolic state, while patients managing conditions like Duchenne muscular dystrophy or myasthenia gravis, often on long-term corticosteroids, tend to face the opposite challenge.

We spoke with Malik, who chaired the Muscular Dystrophy Association’s recent MDA Engage: Chicago session, about how nutrition intersects with disease management, the specific challenges that come up most often, like swallowing difficulty, constipation and bone health, and why she recommends bringing a registered dietitian into a patient’s care team early.

Nutrition needs differ by disease, not just by patient

Malik said neuromuscular disease treatment has advanced significantly over the past decade, with an increasing number of new therapeutics approved. Still, nutrition remains a central piece of disease management, and the specific challenge varies by condition. Patients with ALS, she said, often present with rapid, pronounced weight loss, driven not only by swallowing or hand-strength difficulties but by a hypermetabolic state in which muscles burn more calories than expected. Stabilizing that weight loss, Malik said, can help slow disease progression itself.

Patients with conditions like Duchenne muscular dystrophy or autoimmune neuromuscular disorders such as myasthenia gravis face a different problem. Many are on long-term corticosteroids, which commonly cause weight gain, compounded by limited ability to exercise due to mobility issues. For these patients, Malik said the focus shifts to monitoring caloric intake and maintaining disease stability rather than addressing weight loss.

Swallowing, constipation and bone health

Diseases involving bulbar weakness, affecting speech and swallowing, such as ALS and oculopharyngeal muscular dystrophy, benefit from close collaboration with speech therapists, who teach safe swallowing strategies and recommend texture modifications, like adding moisture or gravy to drier foods, to prevent aspiration.

Constipation is another common issue, often tied to abdominal wall weakness that makes bowel movements more difficult. Malik said the typical approach involves increasing dietary fiber and addressing fluid intake. Bone health is also a concern, particularly for patients on corticosteroids, who face a higher risk of reduced bone density. Malik said her team monitors vitamin D levels closely and supplements aggressively when deficiency or insufficiency is identified.

What “food as medicine” actually looks like

Malik described a general nutritional framework similar to a Mediterranean diet, built around fruits, vegetables, grains, and lean proteins like chicken and seafood, rather than a restrictive elimination diet. Desserts and red meat remain acceptable in moderation, she said, since elimination-style diets tend to be impractical and hard to sustain. Beyond those general principles, Malik emphasized there’s no single nutritional formula that fits every patient, which is why she relies on registered dietitians to tailor plans individually within a team-based care model.

Bringing in a dietitian early

Malik recommends patients connect with a registered dietitian soon after diagnosis, rather than waiting for a nutrition problem to emerge. Once a diagnosis is clear, she said, the care team can anticipate likely future challenges and address them proactively. For patients with ALS specifically, Malik said weight is monitored closely, typically every two to three months, often requiring more frequent dietitian follow-ups than other neuromuscular conditions.

One practical takeaway for families

Asked for one realistic nutrition-related change every family managing a neuromuscular disease should know, Malik pointed back to working with a registered dietitian on texture modifications for safe eating and ensuring adequate intake of lean protein, which she said is critical for preserving muscle bulk and preventing significant weight loss.

Why multidisciplinary care matters

Malik emphasized that neuromuscular diseases are complex, chronic conditions best managed by a full care team, not just a neuromuscular specialist. Beyond dietitians and speech therapists, patients often benefit from physical therapy, occupational therapy and pulmonology, depending on their specific disease. She credited the Muscular Dystrophy Association for championing comprehensive, multidisciplinary clinics that bring multiple specialists together in a single visit, even if that means a two- to three-hour clinic day for patients.
