How to Stop Eating Disorders: Treatment That Works

Eating disorders are treatable, and several therapies have strong evidence behind them. The two with the most research support are enhanced cognitive behavioral therapy (CBT-E) for adults and family-based treatment (FBT) for adolescents, though effective care often involves a layered approach that combines psychological therapy, nutritional rehabilitation, medical monitoring, and sometimes medication. Recovery is real and well-documented, but it rarely follows a straight line, and finding the right combination of treatments matters more than any single intervention.

The Leading Therapy for Adults

CBT-E, developed by Christopher Fairburn at Oxford, is designed to work across all eating disorder diagnoses rather than targeting just one. It addresses the patterns of thinking that maintain disordered eating, including overvaluation of body shape and weight, rigid dietary rules, and the binge-purge cycles that follow from them. A systematic review found robust evidence that CBT-E is effective for adults with bulimia nervosa, binge eating disorder, and other specified feeding or eating disorders.¹

In a head-to-head trial comparing CBT-E with interpersonal psychotherapy (IPT), about two-thirds of CBT-E participants met remission criteria at the end of treatment, compared with about a third in the IPT group. At follow-up, CBT-E still held an advantage, with remission rates of roughly 69% versus 49%.² IPT did catch up somewhat over time, which is worth noting: it suggests that different therapies may work on different timelines, and a slow start does not always mean a treatment has failed.

For adults with anorexia nervosa specifically, the evidence base for any single therapy is thinner. CBT-E has shown effectiveness here too, but anorexia is harder to treat and outcomes tend to be more variable.³ Another approach, the Maudsley Anorexia Nervosa Treatment for Adults (MANTRA), showed significant increases in BMI and reductions in eating disorder symptoms in a feasibility study, though this was a small case series rather than a large trial.⁴ The honest picture is that adult anorexia treatment still lacks the kind of large, decisive trials that bulimia and binge eating disorder have.

Family-Based Treatment for Adolescents

When the patient is a teenager, the strongest evidence points to family-based treatment. FBT flips the usual therapy dynamic: instead of working primarily with the adolescent alone, it positions parents as the central agents of recovery, at least in the early phases. Parents take temporary charge of their child’s eating, then gradually hand control back as the adolescent stabilizes. FBT has emerged as a treatment of choice for adolescent anorexia nervosa, and preliminary evidence suggests it may also work for adolescent bulimia nervosa.⁵

Research from the Maudsley Hospital, where this approach was developed, found that FBT is especially promising for patients with a shorter duration of illness, typically less than three years. The benefits held up at five-year follow-up, and the majority of patients, even severely ill ones, could be treated successfully as outpatients as long as parents were involved.⁶ That last point matters for families weighing their options: FBT can often keep a teenager out of the hospital entirely.

A related program called SUCCEAT, which teaches skills to parents of adolescents with anorexia, found that full or partial remission was observed in 72% to 87% of patients depending on the delivery format. Both in-person workshops and online versions were equally effective, and the improvements held at one-year follow-up.⁷ The fact that online delivery worked just as well as face-to-face is a practical win for families who cannot easily travel to a specialist center.

Medication and Where It Fits

Medication is rarely the main treatment for an eating disorder, but it plays a meaningful supporting role in certain diagnoses. Two drugs have specific FDA approval: fluoxetine (Prozac) for bulimia nervosa, and lisdexamfetamine (Vyvanse) for binge eating disorder.⁸ Both bulimia and binge eating disorder also generally respond to other SSRIs prescribed off-label.

For binge eating disorder, lisdexamfetamine is the only FDA-approved option, though topiramate and various antidepressant and anti-anxiety medications have also shown effectiveness in trials.⁹ For anorexia nervosa, the medication picture is bleaker. No drug has shown reliable effectiveness for weight restoration or the core psychological symptoms of anorexia, though medications are sometimes used to treat co-occurring depression or anxiety.

The practical takeaway: if you or someone you know has bulimia or binge eating disorder, medication combined with therapy tends to work better than either alone. If the diagnosis is anorexia, medication is a sidecar at best, and the main engine of recovery is psychological and nutritional treatment.

Levels of Care

Eating disorder treatment exists on a spectrum from weekly outpatient sessions to round-the-clock hospital care. Outpatient treatment is generally the best starting point and is less disruptive, less expensive, and has shorter waiting lists than inpatient programs. Even patients with severe or extreme anorexia can often be treated as outpatients if they are medically stable.¹⁰

When outpatient care is not enough, the options include intensive outpatient programs (several hours a few days a week), partial hospitalization or day programs (most of the day but you go home at night), residential treatment (you live at the facility), and full inpatient hospitalization. A comparison of residential versus day program treatment found greater improvement from residential care, with medium effect sizes across symptoms.¹¹

For patients at very low body weights, 24/7 care (inpatient or residential) produced significantly greater BMI increases during treatment compared with partial hospitalization or intensive outpatient programs. However, improvements in the psychological symptoms of the eating disorder did not differ between the two settings.¹² In other words, higher levels of care are clearly better at restoring weight quickly, but the psychological work of recovery does not necessarily require a hospital bed. Stepping down to less intensive care after medical stabilization is standard practice and appears well-supported.

Medical Stabilization and Refeeding

For patients hospitalized with severe malnutrition, refeeding is the immediate medical priority and one of the areas where clinical practice has shifted in recent years. Historically, doctors started refeeding slowly out of concern for refeeding syndrome, a potentially dangerous shift in electrolytes that can occur when a starved body suddenly receives nutrition. But newer evidence supports starting at higher calorie levels.

A randomized controlled trial in hospitalized adolescents with anorexia compared higher-calorie refeeding (starting at 2,000 calories per day with increases of 200 calories daily) to lower-calorie refeeding (starting at 1,400 calories per day with slower increases). The higher-calorie group restored medical stability earlier, with no increase in safety events and shorter hospital stays. Over one year of follow-up, clinical remission and rehospitalization rates did not differ between groups, supporting the higher-calorie approach as both safe and more efficient.¹³ Similar findings have been reported in adult patients, where a higher-calorie protocol showed no differences in electrolyte disturbances or clinically diagnosed refeeding syndrome and actually resulted in less hypoglycemia.¹⁴

Alongside refeeding, structured dietetic support can help patients rebuild a functional relationship with food. One manualised intervention delivers five dietitian-led outpatient sessions covering mechanical eating, portion estimation, social eating, and meal planning.¹⁵ Nutritional rehabilitation is not just about calories. It is about building the practical skills needed to eat normally in real-world settings.

Treating ARFID

Avoidant/restrictive food intake disorder (ARFID) looks very different from anorexia or bulimia. People with ARFID are not trying to lose weight or change their body shape. Instead, they severely restrict their diet because of sensory sensitivity to food textures or flavors, fear of choking or vomiting, or a general lack of interest in eating. ARFID was only formally recognized as a diagnosis in 2013, and treatment options are still catching up.

The most developed approach is CBT-AR, a cognitive-behavioral therapy designed specifically for ARFID. It is appropriate for anyone aged 10 and older, runs across 20 to 30 sessions in four stages, and comes in both individual and family-supported versions.¹⁶ The therapy relies heavily on exposure, gradually introducing feared or avoided foods in a structured way. An adapted CBT day treatment program for adolescents with ARFID, integrating exposure principles over a four-week period, has also been tested in clinical settings.¹⁷ Both approaches are relatively new, and larger trials are still underway.¹⁸

What Predicts Recovery and Relapse

One of the most practical questions for anyone in treatment is: what makes recovery more likely? A systematic review and meta-analysis identified several consistent predictors. The single most robust predictor of outcome, both at the end of treatment and at follow-up, was how much symptoms improved early during therapy. Rapid early change is a strong signal that treatment is working. Baseline factors associated with better outcomes included higher BMI at the start, fewer binge-purge behaviors, greater motivation to recover, lower depression, fewer additional psychiatric conditions, and better interpersonal functioning. Dropping out of treatment was predicted by more binge-purge behaviors and lower motivation.¹⁹

Relapse remains common, especially in anorexia nervosa. Factors associated with long-term outcomes across diagnoses include age at presentation, quality of life, the presence of co-occurring conditions, treatment engagement, and access to relapse prevention programs.²⁰ What this means in practice: recovery does not end when formal treatment does. Some form of ongoing support, whether structured relapse prevention, periodic check-ins with a therapist, or a continued relationship with a dietitian, appears to improve the odds of staying well.

What Happens to the Brain During Recovery

Severe malnutrition physically changes the brain. Brain imaging studies have documented reductions in cortical thickness and in the volume of structures like the hippocampus, amygdala, and thalamus in patients with anorexia nervosa. The encouraging finding is that much of this damage reverses with weight restoration. One study found significant global restoration of cortical thickness during treatment, with the fastest recovery in the first phase. Subcortical volumes of the amygdala, caudate nucleus, hippocampus, and thalamus also increased during early treatment. Younger patients showed greater cortical restoration, suggesting that earlier intervention has a biological advantage beyond just a shorter illness duration.²¹

But recovery is not always complete. Research on weight-recovered women with a history of anorexia found that certain cortical regions remained thinner compared with people who had never had the disorder.²² And a study of patients with severe anorexia found that weaker brain connectivity and altered network patterns did not improve even after weight was restored, suggesting that severe illness may leave lasting changes in how the brain processes information.²³ These findings reinforce why early treatment matters: the brain recovers more fully when illness is caught sooner.

Emerging and Experimental Treatments

Several treatments currently under investigation may eventually expand the options available, particularly for patients who have not responded to standard care.

Psilocybin therapy has received early attention. A phase 1 feasibility study gave a single 25-milligram dose of synthetic psilocybin, alongside psychological support, to 10 adult women meeting criteria for anorexia nervosa or partial remission. No clinically significant changes were observed in heart rhythm, vital signs, or suicidality, leading the researchers to conclude that psilocybin therapy is safe, tolerable, and acceptable for this population.²⁴ A broader review of psychedelic-assisted therapy covering psilocybin, ketamine, MDMA, and ayahuasca found preliminary evidence of potential benefit for anorexia and bulimia, though very little data existed for binge eating disorder.²⁵ These are early-stage findings. No psychedelic treatment is ready for clinical use in eating disorders yet, but the safety data is a necessary first step.

Repetitive transcranial magnetic stimulation (rTMS), a noninvasive technique that uses magnetic fields to stimulate brain regions, has shown promising early results in improving mood and reducing core anorexia symptoms.²⁶ Deep brain stimulation (DBS), which involves surgically implanting electrodes in the brain, has been tested in a small randomized trial of patients with chronic, treatment-refractory anorexia. At six months, five participants showed a BMI increase of 10% or more relative to their reference value, and quality of life improved. But the treatment came with complications, including cutaneous issues in three patients, and overall BMI change from baseline to six months was not significant in the simplest analysis.²⁷ DBS remains highly experimental and is relevant only for the most severe, long-standing cases that have resisted everything else.

Who Gets Treatment and Who Does Not

Access to eating disorder treatment is profoundly unequal. People from racial and ethnic minority groups experience eating disorders at rates similar to or higher than white populations but are less likely to receive a diagnosis or treatment. Barriers include cultural stigma, biased diagnostic criteria that were developed primarily with white patients in mind, unequal access to healthcare, and provider bias.²⁸

Insurance type also creates stark divides. In one study, young people with private insurance were three times more likely to receive recommended treatment than those with public insurance. Racial and ethnic minority youth were about 37% less likely to receive recommended care compared with white youth, even in the same model.²⁹ These are not small differences. They mean that effective treatments exist but are not reaching large portions of the people who need them.

The promise of digital and telehealth tools has been held up as one potential solution. Smartphone apps could theoretically extend the reach of evidence-based treatment, but a review of existing eating disorder apps found that most contained minimal evidence-based content and failed to take advantage of smartphone features. The researchers concluded that feasibility, acceptability, and efficacy need to be evaluated before these tools are incorporated into treatment.³⁰ Telehealth delivery of established therapies like FBT and CBT-E, which was accelerated during the COVID-19 pandemic, has shown more promise, but digital tools alone are not yet a substitute for a trained clinician.

Gender, Identity, and Treatment Outcomes

Eating disorders have historically been studied and treated as though they predominantly affect young, white, cisgender women. That picture has always been incomplete, and recent research has started to fill in the gaps. A study comparing treatment outcomes across gender identities in young people found that cisgender boys reported lower eating disorder, anxiety, and depression symptoms at admission compared with cisgender girls. Transgender and gender-expansive (TGE) youth, on the other hand, had significantly higher anxiety, depression, and suicidal ideation at admission. The encouraging finding was that all symptoms improved during treatment at similar rates regardless of gender identity.³¹

The fact that treatment works across gender identities is good news, but the higher psychiatric burden at admission for TGE youth means these patients may need additional support for co-occurring mental health concerns. Cisgender boys and men also face a recognition gap: eating disorders in males are frequently missed or dismissed because clinicians and families may not be looking for them. Ensuring that screening tools and treatment programs are not built solely around the female presentation of eating disorders is one of the more straightforward ways to improve outcomes for everyone.

The Role of Gut Health in Nutritional Recovery

An emerging area of research concerns the gut microbiome and its role in eating disorder symptoms and recovery. The gut microbiome influences mood, appetite, gastrointestinal symptoms, and nutrient metabolism, all of which are disrupted in anorexia nervosa. Current treatment guidelines favor high-calorie diets for weight restoration, often achieved by raising the fat content of meals. But there is growing evidence that balanced, higher-fiber diets may better support a healthy microbiome during recovery.³² This does not mean patients should eat less. It means the composition of what they eat during refeeding could matter for long-term gut and psychological health in ways that are only beginning to be understood. For now, this is an area to watch rather than act on. Dietary decisions during recovery should still be guided by a treatment team, not by microbiome headlines.
