Eating disorders: the psychological approach in practice

A sixteen-year-old who started by cutting out the bread at dinner and now weighs her fruit on a kitchen scale. A man in his forties who eats at night, in secret, and hates himself the next morning. A runner who trains twice as hard on the days she «overdoes it». Eating disorders creep in like this, around the edges, disguised as a diet, as discipline or as a harmless quirk, and by the time someone close raises the alarm they have been settled in for months. This article looks at what eating disorders are, how to recognise them and what a psychological approach that actually works looks like — written for psychologists and teams who treat them in practice.

What eating disorders are

An eating disorder is a mental illness in which a person's relationship with food, weight and their own body becomes distorted to the point of doing harm: physical harm, because the body ends up paying for it, and harm to their life, because food takes over as the centre of everything. It is worth saying plainly from the outset, because the myths are loud: eating disorders are not a teenage whim or a matter of vanity, and they certainly are not cured by «eating a bit more». Underneath there is almost always emotional distress, a difficulty regulating emotions and a body image so distorted that the person sees something in the mirror that does not match reality.

Nor do they wear a single face. We hear a lot about the thin teenage girl, but an eating disorder can appear at any age, in any body and in any gender, and often at weights that look «normal». According to the U.S. National Institute of Mental Health, they are among the mental illnesses with the highest mortality, largely because of their medical complications and the risk of suicide. That is not a figure meant to frighten anyone, but to give them the seriousness they deserve.

The types of eating disorder you'll see in practice

Although everyday language lumps them together, eating disorders come in distinct forms, and it is worth telling them apart, because the treatment changes.

• Anorexia nervosa. Restricted intake, a weight below what would be expected and an intense fear of gaining weight that does not ease even when the body is at risk. The person often experiences their thinness as an achievement, which makes asking for help harder.
• Bulimia nervosa. Binge episodes — eating a large amount in a short time with a sense of loss of control — followed by compensatory behaviours: vomiting, laxatives, fasting or exercise to «undo» what was eaten. Here the weight can be normal, which is why it more often goes unnoticed.
• Binge eating disorder. The same episodes of loss of control, but without any compensation afterwards. It is the most common and the one most often mistaken for «eating out of anxiety», though it is a condition in its own right with its own treatment.
• ARFID. Avoidance or restriction driven by texture, by a fear of choking or by a lack of interest in food, with weight and shape not being the engine. It shows up a lot in childhood and is often written off as being «a fussy eater».
• OSFED. Presentations that do not fully fit the categories above but are just as serious and, in fact, the most common in real-world practice. The lack of a headline name does not make them any lesser.

These categories are laid out in the diagnostic manuals, but in the consulting room they rarely arrive in pure form: what you usually meet are overlaps, shifts from one picture to another and plenty of grey areas. That is why the label matters less than a careful assessment of each case.

Warning signs: why people take so long to ask for help

The big problem with eating disorders is that the person living with one almost never walks in saying «I have an eating disorder». In anorexia, the symptom is experienced as a virtue; in bulimia and binge eating, with a shame that pushes people to hide it. The upshot is that they tend to arrive late, often brought in by a frightened family or referred for some other reason.

It is worth keeping the radar on for certain signs: skipping meals systematically or making excuses not to eat in company, going to the bathroom right after eating, rituals that grow ever more rigid (cutting food into tiny pieces, arranging it, weighing it), exercise that is no longer about health but about obligation, social withdrawal around mealtimes or weight changes with no medical explanation. No single one of these signs confirms anything on its own; it is their accumulation that sets off the alarm. The MedlinePlus health guide offers a solid, plain-language overview for patients and families that you can recommend without hesitation.

The psychologist's role in treating eating disorders

A psychologist's work with an eating disorder starts with an assessment that goes well beyond food. You have to understand the person's history, their body image, how they handle emotions, what the symptom is doing for them — controlling, punishing, soothing — and the state their body is in, because that sets the urgency. That first map decides a great deal: whether outpatient work is possible, how often, and who else needs to be brought into the process.

From there, the intervention works on several fronts at once: restoring a regular pattern of eating, dismantling the fear of weight and the rigid rules, working on body image and, almost always, tending to what lies beneath — usually anxiety, perfectionism or deeper emotional difficulties. With minors, the family is not an add-on: it is part of the treatment. And there is a principle worth keeping in mind: therapeutic ambition has to walk arm in arm with clinical caution, knowing when a case is beyond us and it is time to refer or call in medical support.

Evidence-based psychological treatments

The good news is that eating disorders can be treated, and that there are scientifically backed approaches depending on the condition and the age of the person.

In adults, cognitive behavioral therapy in its version tailored to eating disorders — the well-known CBT-E — is the reference treatment for bulimia and binge eating disorder, and a solid option in anorexia. When the eating problem coexists with intense emotional dysregulation or borderline traits, dialectical behavior therapy offers very useful tools for tolerating distress without turning to bingeing or purging.

In adolescents with anorexia, family-based treatment — the so-called Maudsley model — has changed the picture: instead of leaving parents on the sidelines, it gives them an active role in weight recovery, with professional guidance. The leading clinical guidelines, such as those from the UK's NICE, set out well what works in each situation. The practical conclusion is always the same: there is no single recipe, and the plan is tailored to the person, their environment and the severity of the condition.

Why eating disorders are best treated as a team

An eating disorder touches mind and body at once, so it often overflows what a single professional can hold. A moderately severe case calls, at the very least, for psychology to do the therapeutic work, medicine or psychiatry to watch over the physical risk and any comorbidity, and nutrition to rebuild a healthy relationship with food. The family often joins in too. And everyone has to row in the same direction, because eating disorders are experts at exploiting the cracks: if one professional says one thing and another says the opposite, the disorder slips right through.

That coordination is, in practice, one of the hardest parts. You have to share just the right information between professionals — the course of the weight, the risks, the goals — without pouring out the intimate things the person tells you in session. For a psychology practice treating eating disorders, keeping the team's clinical records in one place, with clear permissions over who sees what, is not about convenience: it is clinical safety and respect for confidentiality at the same time.

How to organise your practice to treat eating disorders

The clinical side is demanding enough on its own; the logistics, if you don't sort them out, will eat your evenings. And eating disorders have a particular back office. They are long treatments, months at a time, with frequent sessions that cannot be left to the mercy of «I'll call to book»: a calendar that holds that cadence and does not leave two-week gaps makes a real difference to adherence.

As with any treatment that drags on, no-shows are the silent enemy; WhatsApp reminders cut down on forgotten appointments without you having to chase anyone. A good share of your patients will be minors, so you need consents ready for them and their guardians, and a clinical record worthy of health data: encrypted, well ordered and with progress carefully logged session by session. And then there is coordination with the rest of the team, which we have already seen is delicate: what you share with nutrition or medicine is what has been agreed; the rest stays under your professional confidentiality. Having the software hold that boundary, rather than mixing everything together, is part of the job.

My Psico Agenda: the back office of your practice, in one panel

My Psico Agenda is management software built for psychologists and therapists. It brings together, in one account, the calendar with automatic WhatsApp reminders, the encrypted clinical record, consents signed in session or remotely, the patient portal and VeriFactu-compliant invoicing, all under the GDPR and with servers in the European Union. It runs in the browser, on the phone and on the tablet, with nothing to install.

You start with the plan for self-employed psychologists from €19.99/month, with no lock-in, and cancel whenever you want. If you treat eating disorders as a team, the version for psychology practices brings the whole team's calendars and clinical records together in one panel, with permissions per professional, so coordination doesn't turn into a mess of emails. It's all on the plans and pricing page.
