Disordered Minds, Disordered Meals: When Emotions Masquerade as Hunger in Eating Disorders-A Systematic Review

Emotion dysregulation and altered interoceptive processing are increasingly recognized as core processes in eating disorder (ED) psychopathology. Difficulties in identifying, tolerating, and regulating negative emotional states may interact with reduced trust in bodily signals and distorted interpretation of hunger and satiety cues, contributing to maladaptive eating behaviors. The aim of this PRISMA-guided qualitative systematic review was to synthesize original empirical evidence on the interaction between emotion dysregulation and interoceptive processing in EDs, with particular attention to how emotional distress may be misinterpreted as physical hunger or food-related urges. A systematic search of PubMed and Scopus identified 78 records; after removal of duplicates and screening procedures, 24 original empirical studies were included in the qualitative synthesis. Across ED presentations, emotion dysregulation consistently emerged as a central transdiagnostic process associated with symptom severity, impulsivity, maladaptive eating behaviors, and related risk outcomes. Interoceptive alterations were widely reported, particularly involving reduced body trust and distorted interpretation of internal sensations rather than a uniform deficit in interoceptive sensitivity. The reviewed studies also showed that emotional states and cognitive expectations may shape the appraisal of hunger and satiety cues, contributing to the misinterpretation of emotional distress as physiological need across restrictive, binge-purge, and binge-eating presentations. The findings support a close interplay between emotion dysregulation and altered interoceptive processing in EDs and highlight the clinical relevance of interventions that integrate emotion regulation and interoceptive awareness to promote more adaptive eating behaviors.
