Adherence

Orthorexia nervosa is a pathological fixation on healthy food that leads to nutritional deficiencies, medical complications, and poor quality of life, distinguishable from anorexia by its motivation (health/purity vs. weight loss) and from OCD by its ego-syntonic nature.

If you find yourself spending hours scrutinizing food labels, avoiding entire food groups due to 'purity' concerns, or feeling intense guilt when eating 'impure' foods, this may be orthorexia. Unlike healthy eating, it causes distress, social isolation, and potential medical issues. Seek help from a multidisciplinary team (therapist, dietitian, physician) if your diet is restricting your life.

Orthorexia nervosa describes a pathological obsession with proper nutrition that is characterized by a restrictive diet, ritualized patterns of eating, and rigid avoidance of foods believed to be unhealthy or impure. Although prompted by a desire to achieve optimum health, orthorexia may lead to nutritional deficiencies, medical complications, and poor quality of life.
