Restrictive Eating

Restrictive eating is a broad term describing patterns of food intake in which an individual intentionally limits the quantity, variety, timing, or types of food consumed. Restriction may be volitional and non-clinical — as in dieting for weight management, adherence to specific dietary patterns (e.g., low-carbohydrate, plant-based, or religious/cultural practices), or avoidance of foods due to preference, allergy, or intolerance — or it may occur within clinical contexts, as a core feature of eating disorders such as anorexia nervosa, avoidant/restrictive food intake disorder (ARFID), and the restrictive subtype of other specified feeding or eating disorders.

Restrictive eating can involve limits on total energy intake, specific macronutrients, food groups, sensory characteristics (texture, appearance), or eating windows, and its psychological and physiological consequences depend on the degree, duration, and motivation of restriction. Depending on context, restrictive eating may support health-related goals or, when severe or prolonged, contribute to nutritional deficiencies, metabolic and endocrine disturbances, disordered eating patterns, and impaired cognitive, emotional, and psychosocial functioning.
