Compulsive overeating and binge eating disorder (BED) describe a maladaptive pattern of eating characterized by recurrent episodes of eating an objectively large amount of food accompanied by a sense of loss of control. The seed idea in the prompt—”eat a whole tub”—reflects a behavior that can align with binge-type eating, where consumption becomes disproportionate to hunger and is followed by distress rather than pleasure. BED is now recognized as a distinct eating disorder in major diagnostic systems and is associated with significant medical comorbidity and psychosocial impairment.
Mechanistically, BED involves dysfunction across reward, stress, and inhibitory control systems. Neurobehavioral models emphasize that binge episodes occur when heightened reward salience of palatable foods converges with impaired top-down regulation. The brain’s reward circuitry, including dopaminergic pathways and cortico-striatal networks, can become sensitized to food cues, such that environmental triggers (availability, advertising, social contexts, emotional states) elicit cravings and approach behavior. Simultaneously, executive control networks in the prefrontal cortex may underperform, reducing the capacity to inhibit consumption despite negative consequences.
Stress biology is also central. Many individuals experience BED episodes during or after stress, anxiety, or dysphoric mood. Chronic stress may dysregulate hypothalamic-pituitary-adrenal (HPA) axis signaling and autonomic arousal, increasing vulnerability to impulsive coping behaviors such as binge eating. Additionally, emotional regulation difficulties—trouble identifying, tolerating, or modulating negative affect—can lead to binge eating as an immediate, albeit transient, form of relief.
Clinically, BED is diagnosed when binge episodes occur at least weekly for a defined period, with marked distress about the binge pattern. Binge episodes must include both (1) eating an amount of food that is clearly larger than most people would eat in a similar period and (2) a perceived lack of control during the episode. Unlike bulimia nervosa, BED typically does not involve recurrent compensatory behaviors such as self-induced vomiting or misuse of laxatives. However, individuals may use compensatory restriction later, which can perpetuate a cycle of deprivation, rebound hunger, and subsequent bingeing.
Medical sequelae can include obesity, type 2 diabetes, dyslipidemia, hypertension, and obstructive sleep apnea, though BED can occur across weight categories. The disorder also carries risk for gastrointestinal complications, fatty liver disease, and inflammation-related metabolic changes. Psychological comorbidity is common: depression, anxiety disorders, and substance use disorders frequently co-occur, and shame-based rumination may reinforce binge behavior.
Evidence-based treatment integrates psychological and behavioral interventions with, when indicated, pharmacotherapy. First-line psychotherapy includes cognitive behavioral therapy for BED (CBT-BED), which targets the cognitive distortions and behavioral triggers that maintain binges. CBT-BED helps patients regularize eating patterns, reduce restrictive dieting, improve coping skills for urges, and challenge beliefs that drive binge behavior. Interpersonal psychotherapy (IPT) is another effective approach that focuses on role transitions, interpersonal conflicts, and grief, reducing binge behavior via improved relationship functioning and mood regulation.
Pharmacologic options may be considered for moderate to severe BED, especially when psychotherapy alone is insufficient or when rapid symptom reduction is desired. Lisdexamfetamine, a stimulant prodrug, has demonstrated efficacy in reducing binge frequency in some patients; selective serotonin reuptake inhibitors (SSRIs) may help with comorbid depression and anxiety, and for some, with binge frequency—particularly when dieting is less prominent. Other agents have been studied, including topiramate and medications targeting craving and impulsivity pathways, but selection should be individualized based on comorbidities, contraindications, and patient preferences.
A key clinical principle is assessing severity and risk. Clinicians evaluate frequency of binges, level of distress, history of self-harm, suicidal ideation, and medical complications. Nutrition counseling may complement therapy, but diet plans should avoid extreme restriction that can increase binge vulnerability. For urgent cases where binge eating is accompanied by severe medical instability or acute psychiatric risk, coordinated care with primary care and mental health professionals is essential.
For prevention and self-management, reducing binge triggers is often effective: identifying cue patterns, practicing urge-surfing strategies (delaying action until urges subside), and creating structured meal routines to prevent extreme hunger. Sleep regularity and stress reduction (mindfulness, behavioral activation, and, when appropriate, treatment of anxiety or depression) can reduce physiological arousal that primes binge episodes.
Overall, compulsive overeating consistent with BED is best understood as a disorder of impaired control under conditions of heightened reward and emotional stress. Effective care typically requires sustained, structured interventions that restore regulatory capacity, address cognitive and interpersonal drivers, and—when indicated—use targeted medications to reduce binge frequency and improve quality of life.
