# Nutrition in Becker muscular dystrophy
Mediterranean dietary pattern
ResearchediPositive results in clinical studies, not yet standard treatment
The Mediterranean pattern consists of many vegetables, fruit, nuts, whole grains, fish and olive oil, with limited red meat and dairy. This dietary pattern contains many antioxidants and anti-inflammatory substances.
In muscle diseases, including dystrophies, research examines whether such a dietary pattern may be useful because of its anti-inflammatory properties. The general health benefits of this pattern are well documented, but specific studies of this pattern *only* in Becker muscular dystrophy are limited. The pattern aligns well with what clinicians recommend for someone with reduced mobility: many nutrients, fewer saturated fats, and support for heart and bone health.
Protein-rich nutrition
ResearchediPositive results in clinical studies, not yet standard treatment
A protein-rich diet contains more protein than average recommended, via meat, fish, eggs, cheese, yoghurt or plant-based sources such as beans and tofu. For muscle tissue, protein is a building block.
In muscle diseases, research examines how protein intake and muscle maintenance are related. Studies of nutritional status in boys with Duchenne dystrophy (a more severe form than Becker) show that malnutrition and insufficient protein intake occur and can be harmful. In Becker muscular dystrophy, where the condition progresses more slowly, adequate protein intake seems important for maintaining as much muscle strength as possible — but this does not replace physiotherapy or other treatment. Sufficient protein can also help with recovery after exertion.
No known risks at normal amounts, but very high doses can be problematic in kidney damage; this is discussed with the treating clinician.
Diet low in saturated fats and sugar
ResearchediPositive results in clinical studies, not yet standard treatment
This pattern limits fatty meat, fried food, high-fat dairy products, and sugar and sugary drinks and sweets.
Recent animal studies show that a diet high in fat and high in sugar worsens muscle damage in dystrophies and undermines the action of glucocorticoids (anti-inflammatory medicines that are widely used). This suggests that *avoiding* such a diet may help. In people with reduced mobility, weight gain also occurs more readily, which creates extra strain. A diet lower in saturated fats and added sugars aligns with preventing additional heart and metabolic problems.
Diet with attention to micronutrients
ResearchediPositive results in clinical studies, not yet standard treatment
This includes sufficient vitamins and minerals, especially iron, zinc, vitamin D, and B vitamins — via vegetables, fruit, whole grains, meat, fish, nuts and dairy.
Research shows that malnutrition and deficiencies in certain micronutrients occur in dystrophy patients. Zinc status has been studied in Duchenne dystrophy (related to Becker), and zinc supplementation produced measurable changes in certain parameters. Vitamin D is important for bone and muscle tissue, especially with reduced physical activity. The condition itself, or certain medicines, can impair nutrient absorption.
Risks at very high doses are known; supplements should be under the supervision of the treating clinician.
Periodic fasting
ExperimentaliOngoing in study setting, outcome still unknown
Periodic fasting restricts food intake to certain hours of the day, or eating very little one or two days per week.
In animals with muscle dystrophy, research has examined whether fasting provides any benefits. Some studies suggest that certain types of movement pattern combined with dietary changes have favourable effects on muscle strength and weight. However, specific and stable findings on periodic fasting in Becker muscular dystrophy are lacking. For someone with limited muscle strength, irregular eating can pose risks, such as insufficient energy and nutrients, especially if mobility is already restricted.
Ketogenic or very low carbohydrate diet
UnproveniNo scientific evidence that it works
A ketogenic diet is very low in carbohydrates, high in fat, and forces the body into fat burning. This diet is being studied in various neurological diseases, but not specifically in Becker muscular dystrophy.
There is no research that recommends or advises against this diet for this condition. Because muscles rely heavily on carbohydrates for energy, and because someone with Becker already struggles with muscle problems, such a drastic change without guidance would be unwise. Not recommended without supervision.

**Nutritional choices are tailored to the individual.** Everyone with Becker muscular dystrophy has a different disease course, different medication use, and different comorbidities. What nutrition is suitable depends on energy, nutrient, and chewing needs, on weight and growth (especially in young people), on medication side effects, and on what the muscles and stomach can tolerate. A dietitian with experience in muscle diseases can work together with your treatment team to create a plan that fits your situation and treatment.
