Binge eating disorder (BED) is recurrent episodes of eating large amounts of food rapidly, with loss of control and significant distress, at least once weekly for 3 months — without purging or compensatory behaviors. It's the most common eating disorder in the US. CBT-E achieves remission in 60–80% of cases. DSM-5 code: 307.51, ICD-10: F50.81.
Binge eating disorder (BED) is the most common eating disorder in the United States, affecting approximately 2.8% of adults at some point in their lives — more than anorexia and bulimia combined. Yet it received its own official DSM-5 diagnosis only in 2013, previously categorized as "Eating Disorder Not Otherwise Specified" (EDNOS).
BED is characterized by recurrent episodes of uncontrolled overconsumption of food, accompanied by marked distress, but without the compensatory behaviors (purging, excessive exercise, laxative use) that define bulimia. The loss-of-control experience — not the amount eaten — is the defining feature.
For a clinical BED diagnosis, all three conditions must be met:
| Population | Lifetime Prevalence |
|---|---|
| All US adults | ~2.8% |
| Women | ~3.5% |
| Men | ~2.0% |
| Adolescents | ~1.6% |
| Adults seeking weight loss treatment | ~25–30% |

BED is not caused by any single factor. Research identifies a cluster of interacting contributors:
Biological: Genetic predisposition (heritability estimated at 41–57%), abnormalities in dopamine reward signaling, and leptin/ghrelin dysregulation that impairs hunger and satiety cues.
Psychological: Difficulty tolerating negative emotions (especially shame, anxiety, and loneliness), low distress tolerance, maladaptive perfectionism, and impulsivity. BED has high comorbidity with depression (50%), anxiety disorders (65%), and ADHD.
Behavioral: History of chronic dieting or weight cycling. Restriction creates physiological and psychological pressure that makes loss-of-control eating more likely. Studies consistently show that dietary restraint precedes and predicts binge onset.
Environmental: Trauma and adverse childhood experiences, weight stigma, chaotic home eating environments, and food insecurity.
| Feature | BED | Bulimia | Food Addiction (YFAS) |
|---|---|---|---|
| Binge episodes | Yes | Yes | Often |
| Loss of control | Yes | Yes | Yes |
| Compensatory behavior | No | Yes | No |
| Tolerance / withdrawal | Not a criterion | Not a criterion | Yes |
| Craving specific substances | Not a criterion | Not a criterion | Yes |
| Official DSM-5 diagnosis | Yes (307.51) | Yes (307.51) | No |
Left untreated, BED is associated with significant medical and psychiatric morbidity. The most common include: type 2 diabetes (3× increased risk), hypertension, dyslipidemia, sleep apnea, gastrointestinal problems (GERD, IBS), depression and anxiety disorders, and substantially reduced quality of life. BED is associated with higher all-cause mortality in population studies, primarily through metabolic disease.
Targets the thoughts, emotions, and behavioral patterns driving the binge cycle. Typically 16–20 weekly sessions. Addresses dietary restraint, emotion regulation, and the role of weight/shape concerns. Self-guided CBT using validated workbooks (Fairburn, 2013) achieves approximately 40–50% remission.
Developed for emotion dysregulation. Particularly effective when BED is driven by difficulties tolerating negative emotions. Skills modules: mindfulness, distress tolerance, emotion regulation, interpersonal effectiveness. Recommended when CBT-E has not achieved remission.
Focuses on improving interpersonal functioning rather than food/eating directly. Based on the finding that interpersonal problems (grief, role disputes, life transitions, isolation) are common precipitants of BED. Equivalent to CBT-E at 12-month follow-up in multiple RCTs.
The only FDA-approved medication for BED (approved 2015). Reduces binge days per week by ~3 compared to placebo in Phase III trials. Works on dopaminergic and noradrenergic pathways. Not appropriate for everyone — consult a psychiatrist. Typically recommended in combination with therapy, not as monotherapy.
Seek professional support if binges occur more than once per week, you are in significant distress, physical health is affected, or if self-managed approaches have not helped after 4–6 weeks. BED is highly treatable — the evidence consistently shows that early intervention leads to better outcomes and lower relapse rates.

Three or more of five markers must be present: eating faster than normal, eating until uncomfortably full, eating large amounts when not hungry, eating alone due to embarrassment, or feeling disgusted/depressed/guilty after. DSM-5 code: 307.51.
Cognitive Behavioral Therapy (CBT-E) is the gold-standard treatment with 60–80% remission rates. Dialectical Behavior Therapy (DBT), Interpersonal Psychotherapy (IPT), and guided self-help using CBT methods are also effective. Lisdexamfetamine (Vyvanse) is the only FDA-approved medication for moderate-to-severe BED.
Yes. BED is associated with obesity, type 2 diabetes, hypertension, sleep apnea, gastrointestinal problems, depression, and anxiety. However, it has the best treatment outcomes of any eating disorder — 60-80% achieve remission with CBT.
Yes. While BED is associated with overweight and obesity in population studies, it occurs across all body sizes. Weight is not a diagnostic criterion for BED. People of any weight can receive a BED diagnosis.
The key distinction is compensatory behavior. Bulimia nervosa involves purging (vomiting, laxatives, excessive exercise) after binge episodes. BED does not. Both involve recurrent binge episodes causing significant distress, but the absence of compensatory behavior is what separates a BED diagnosis from bulimia.
