Orthorexia Nervosa

Orthorexia nervosa is an excessive preoccupation with maintaining a diet that is “healthy” or “pure” and includes fears around the consumption of foods or ingredients perceived as “unhealthy” or “impure”. This fixation on healthy eating creates psychological distress and can be socially isolating. Self-imposed dietary restrictions may lead to weight loss and nutritional deficiencies.

How It Works

Orthorexia nervosa is an unhealthy obsession with 'healthy' or 'pure' eating. Unlike anorexia which focuses on weight loss, orthorexia focuses on food quality and purity. This fixation can lead to nutritional deficiencies, social isolation, and significant psychological distress.

CHARACTERISTICS of orthorexia:

Obsessive focus on food quality, purity, or 'healthiness'
Rigid rules about which foods are 'allowed'
Distress or guilt when eating 'impure' foods
Progressive elimination of food groups
Social isolation due to food rules
Sense of moral superiority about eating
Time-consuming food research and preparation
Paradoxically, malnutrition from excessive restriction

CRITICAL: Orthorexia is a serious eating disorder that requires professional treatment. This protocol addresses nutritional deficiencies only.

PROFESSIONAL HELP includes:

Eating disorder specialist: Essential for recovery
Psychotherapy: CBT, exposure therapy for food fears
Registered dietitian: Meal planning, nutritional rehabilitation
Medical monitoring: For nutritional deficiencies
Psychiatric evaluation: For co-occurring anxiety, OCD

WHY NUTRITIONAL DEFICIENCIES OCCUR:

Paradoxically, the pursuit of 'healthy' eating can cause deficiencies:

Avoiding fats = low omega-3s, fat-soluble vitamins
Avoiding animal products = low B12, zinc, iron
Avoiding 'processed' foods = may miss fortified nutrients
Limited variety = multiple micronutrient gaps

* Zinc is particularly important as it affects appetite regulation and mood.

* B vitamins and Omega-3s support brain function and mood.

* Iron and Vitamin D are commonly deficient in restrictive eating patterns.

Expected timeline: Recovery from orthorexia takes months to years with professional help. Correcting nutritional deficiencies takes weeks to months. Supplements should be introduced with guidance from a dietitian who understands eating disorders.
