Between Normality and Pathology: Anorexic Readiness Syndrome (ARS/SGA) – Clinical Signs, Psychology, and Prevention

The concept of Anorexic Readiness Syndrome was formulated to delineate adolescent and adult cohorts who manifest rigid dietary restriction and obsessive weight preoccupation without satisfying the full diagnostic thresholds for DSM-5 anorexia nervosa.

Hallmarks include rigid cognitive dichotomy labeling foods as strictly 'safe' or 'toxic', acute postprandial guilt, avoidance of communal dining, and compulsive gram-by-gram caloric tracking. This manifestation does not reflect genuine lack of appetite, but an overwhelming dread of adiposity and loss of personal control.

The progression of ARS steadily erodes interpersonal relationships. Prominent behavioral trajectories include:

• Compulsive, punitive exercise: Physical exertion is weaponized solely to 'compensate' for caloric intake, regardless of systemic fatigue, musculoskeletal injury, or environmental hazards;
• Medicalized elimination disguises: Adopting restrictive exclusion diets (strict gluten-free, dairy-free, raw veganism) devoid of clinical indications, functioning covertly to eliminate lipid and carbohydrate density;
• Affective lability and irritability: Secondary to sustained neuroenergetic deficits, suppressed leptin signaling, and blunted central serotonergic tone.

Unaddressed Anorexic Readiness Syndrome frequently escalates into clinical anorexia or bulimia nervosa. Successful early resolution combines psychodietetics and Cognitive Behavioral Therapy (CBT):

Core strategies center on decoupling self-worth from body metrics, systematic desensitization through the graded reintroduction of eliminated 'fear foods', and restoring intuitive interceptive awareness of physiological hunger and satiety cues. Cultivating empathetic, weight-neutral family environments remains the strongest protective shield.
