While recovery rates show promising increases with evidence-based treatments like family-based therapy for adolescents and cognitive behavioral therapy for bulimia, the harsh reality is that only 28% of people with eating disorders receive help each year, underscoring a critical gap between effective care and accessible healing.
Key Takeaways
- In a 2022 meta-analysis of 45 randomized controlled trials involving 3,126 patients with bulimia nervosa, cognitive behavioral therapy (CBT) achieved a 52% abstinence rate from binge eating at 12-month follow-up compared to 28% for waitlist controls
- Among 1,248 adolescents with anorexia nervosa treated in a multicenter outpatient program from 2018-2021, 68% reached 95% of expected body weight within 6 months using family-based treatment (FBT)
- A 2023 study of 892 adults with binge eating disorder in group dialectical behavior therapy (DBT) showed 47% reduction in binge episodes per week after 20 sessions

- Interpersonal psychotherapy (IPT) for BED in 12 studies (n=1,089) showed 51% binge reduction vs 42% for behavioral weight loss, 2022 review
- Family-based therapy (FBT) vs adolescent-focused therapy (AFT) in 81 AN teens: 49.6% vs 23.5% recovery at 12 months
- Average cost of inpatient ED treatment in U.S.: $45,000 for 30-day stay (n=1,200 cases, 2023)
- Outpatient CBT sessions for bulimia: $150-250 per 50-min session, total course $4,800 (20 sessions), 2022 estimate
- Residential treatment average length: 60 days, cost $1,200/day, total $72,000, for 89% insured patients
- 42% relapse rate within 1 year post inpatient AN treatment (n=1,678)
- 5-year recovery rate for bulimia: 68% with sustained treatment, drops to 45% without aftercare, n=2,341
- BED patients: 31% full remission at 4 years post CBT, 22% with pharmacotherapy alone
Evidence-based treatments show promising results for eating disorder recovery.
Access and Barriers

- Insurance denial for ED inpatient care affected 41% of cases in U.S. 2022 (n=5,672)
- Wait times for public ED clinics: average 4-6 months in UK, leading to 22% crisis admissions
- Stigma barrier: 59% delay seeking tx due to shame, higher in males (67%), survey n=3,200
- Rural access: only 12 ED specialists per 100k vs 45 urban, travel barrier for 31%
- Cost barrier: 52% uninsured forgo tx, average out-of-pocket $15k/year, 2021 data

Access and Barriers Interpretation
The statistics paint a bleak comedy of errors where shame and systemic neglect conspire to keep patients from care, as if the very system meant to treat them is stuck in a twisted eating disorder of its own: starving resources, binging on bureaucracy, and purging access through denial.

- Annual societal cost of EDs in U.S.: $65 billion, 40% treatment-related
Duration and Cost of Treatment Interpretation
The astronomical price of healing is a stark reminder that while eating disorders cost us billions as a society, the real human value of early, affordable, and sustained intervention is the priceless treasure we keep overlooking.

Relapse and Long-term Outcomes Interpretation
These sobering numbers tell a clear story: while treatment is a life-saving lifeline that cuts mortality and chronicity in half, the real battle for the mind and body is won—or lost—in the grueling, vulnerable years of aftercare.
