How could diet affect body dysmorphic disorder?

It is well known that nutrition and diet can impact brain health.^[1] However, there is currently a lack of nutritional studies specifically focused on BDD. As a result, there is limited knowledge regarding potential nutritional deficiencies and the related dietary adjustments that could be beneficial for individuals with BDD.

Although specific interventions for nutrition and diet in BDD are not yet available, research has shown that people with BDD are more likely to also have an unhealthy relationship with food, which may contribute to the presence of an eating disorder. It is important to note that eating disorders are distinct from BDD and can occur as a consequence or symptom of body dysmorphia.^[2] Furthermore, individuals with muscle dysmorphia often adhere to very strict diets that are typically high in protein and low in fats, and some individuals may also use supplements and/or anabolic steroids in an attempt to achieve their desired body shape more quickly.^[3] All of these unhealthy eating patterns can potentially result in nutritional deficiencies and correlated issues, which should be addressed alongside BDD signs and symptoms.
