Eating Disorders: Evidence-Based Psychological Treatment in Bella Vista

The Dinner You Kept Rehearsing All Day

It is 4:47pm on a Wednesday. Dinner is at seven. You have spent parts of today thinking about what will be on the table, how much of it you will eat, what you will say if someone offers seconds, whether you will need to move for an hour afterwards, and whether tomorrow’s breakfast will need to compensate for tonight. In the car, in the meeting, in the queue at Woolies — the calculations kept running in the background like a browser tab you could not close.

You have told yourself for years that this is just being “careful”, or “disciplined”, or “into wellness”. The people around you have often praised it. You have quietly not mentioned the part where the calculations do not stop, where the flexibility to eat what other people are eating has narrowed year by year, where the shame after a slip is disproportionate to the slip, and where — some nights — the whole thing tips into a binge and the day ends worse than it started.

If any of this is familiar, please read on. Eating disorders are serious, treatable clinical conditions — not lifestyle choices, not vanity, not failures of willpower. They affect people of every age, gender, cultural background, and body size. And with the right treatment, most people recover.

What Counts as an Eating Disorder

The current DSM-5 framework recognises several eating disorder diagnoses. Understanding the range matters, because the stereotype — a very young, very thin girl refusing food — represents only a small slice of who is actually affected.

• Anorexia nervosa (AN) — persistent restriction of energy intake, intense fear of weight gain or persistent behaviour that interferes with weight gain, and disturbance in body-image experience. Includes an “atypical” presentation in people whose weight is within or above the healthy range.
• Bulimia nervosa (BN) — recurrent binge eating followed by compensatory behaviours (vomiting, laxatives, fasting, excessive exercise), occurring on average at least weekly.
• Binge eating disorder (BED) — recurrent binge eating without regular compensatory behaviours; the most common eating disorder in adults, and often the most under-diagnosed. It is covered in more depth in our guide to binge eating disorder treatment in Bella Vista.
• ARFID (Avoidant/Restrictive Food Intake Disorder) — restrictive eating not driven by body-image concerns but by sensory sensitivity, fear of aversive consequences (choking, vomiting), or low interest in food.
• OSFED (Other Specified Feeding or Eating Disorder) — clinically significant patterns that do not fit neatly into the categories above. OSFED accounts for a large proportion of people who present for treatment and is not a “mild” or “sub-clinical” diagnosis.

Eating disorders have among the highest mortality rates of any mental health condition, largely from medical complications and suicide (Arcelus et al., 2011). This is not a minor issue to sit with quietly. Early treatment matters.

Who Actually Gets Eating Disorders

The stereotype is out of date and materially harmful. Eating disorders affect men and women, adolescents and adults, people across body sizes, and people from every cultural background. Recent Australian data suggest around one in twenty Australians is living with an eating disorder at any given time (Butterfly Foundation / Deloitte, 2024). Rates in men, midlife women, and culturally and linguistically diverse communities are underestimated in older figures — largely because the stereotype delayed both help-seeking and clinician recognition.

In my clinical practice in Bella Vista, I most often see adults in their 20s to 50s who have quietly lived with disordered eating for a decade or more before seeking help. Many carry an atypical anorexia, a bulimic pattern that has never been named, or a binge eating disorder that arrived alongside a stressful life stage — a divorce, a bereavement, perimenopause, a promotion, a move. The common thread is not weight. It is that food, body, and eating have taken up more mental real estate than they should.

What Drives Eating Disorders

Eating disorders are biopsychosocial. There is no single cause. Contemporary aetiological models (Culbert et al., 2015; Treasure et al., 2020) point to an interaction of:

• Genetic and temperamental predisposition — heritability estimates for anorexia and bulimia sit around 50–60%. Perfectionism, anxiety-proneness, and high harm-avoidance are common temperamental features.
• Neurobiological factors — starvation itself changes the brain, entrenching restrictive patterns; reward-system alterations contribute to binge-purge cycles.
• Psychological factors — low self-esteem, difficulty tolerating strong emotion, over-reliance on weight and shape for self-worth, trauma history, and perfectionism.
• Sociocultural pressures — weight-focused messaging, diet culture, social media, and the moralisation of food and bodies.
• Life-stage transitions — puberty, leaving home, pregnancy, postpartum, perimenopause, and major losses are frequent onset windows.

Understanding this multi-factor picture matters because it makes clear that recovery is not a matter of “just eating” or “just willpower”. It is a matter of treating a serious condition with the right combination of medical, nutritional, and psychological care.

Why Team-Based Care Is Non-Negotiable

Eating disorders sit at the intersection of physical and mental health. Restrictive eating produces measurable cardiac, endocrine, gastrointestinal, and cognitive effects. Purging produces its own dangerous physical sequelae. Refeeding — the process of nutritional restoration — has its own medical risks that must be monitored. No psychologist works alone in this space, and any clinician who suggests otherwise is not practising to best-practice standards.

The National Eating Disorders Collaboration (NEDC, 2023) and RANZCP (2014) both endorse a coordinated team model:

• GP — physical monitoring (weight, vitals, bloods, ECG where indicated), medical safety, referrals
• Psychologist — evidence-based psychological treatment
• Accredited Practising Dietitian — with eating-disorder-specific training; nutritional rehabilitation and meal-planning support
• Psychiatrist — where medication, higher-level care, or complex comorbidity requires it
• Family or key support person — where appropriate and consented to

In my Bella Vista practice, I work within this team structure. Where you do not yet have a GP or dietitian with eating-disorder experience, I help you find one before we begin.

The Evidence-Based Psychological Treatments

The strongest evidence for adults across diagnoses centres on a small number of protocols. For a broader overview of what the profession recommends, see our summary of the evidence-based therapies for eating disorders recommended by the APS.

CBT-E (Enhanced Cognitive Behaviour Therapy). Developed by Christopher Fairburn and colleagues at Oxford, CBT-E is the current first-line psychological treatment for adults across eating disorder diagnoses (Fairburn, 2008; Fairburn et al., 2015). It works with the shared “core psychopathology” — over-evaluation of weight, shape, and eating control — that runs across anorexia, bulimia, BED, and OSFED. As an enhanced form of cognitive behaviour therapy, treatment is structured, transdiagnostic, and typically runs 20 sessions (40 for underweight presentations).

MANTRA (Maudsley Model of Anorexia Nervosa Treatment for Adults). Developed by Schmidt, Treasure, and colleagues at King’s College London, MANTRA is designed specifically for adults with anorexia nervosa and targets the cognitive, socio-emotional, and interpersonal maintaining factors of the illness. The MOSAIC trial (Schmidt et al., 2015) demonstrated MANTRA’s effectiveness alongside SSCM (Specialist Supportive Clinical Management) as first-line outpatient options for adults with AN.

FBT (Family-Based Treatment). For adolescents, family-based treatment (Le Grange & Lock, 2007) is the strongest-evidenced option and involves parents actively supporting nutritional restoration. Elements of FBT can be adapted for young adults still living at home with supportive families.

DBT-informed skills work. For bulimia nervosa and binge eating disorder specifically, DBT-based skills (Safer et al., 2009) — particularly distress tolerance, emotion regulation, and mindfulness — target the emotion-driven eating patterns that often maintain the disorder. DBT skills are frequently integrated into eating disorder treatment where affect dysregulation is prominent.

IPT (Interpersonal Psychotherapy) — for bulimia and BED — targets interpersonal difficulties that maintain the eating disorder and has RCT evidence as an alternative to CBT-E (Wilson et al., 2010).

Medication. SSRIs (particularly fluoxetine, the only medication with a specific indication for bulimia nervosa) and, for BED, lisdexamfetamine may be helpful adjuncts, prescribed by a GP or psychiatrist.

How I Work with Eating Disorders

In my Bella Vista practice, I combine evidence-based structured protocols with a formulation approach tailored to the person in front of me. Early sessions focus on assessment, formulation, and building the team around you. I do not begin psychological treatment without confirmed GP monitoring and, in most cases, a dietitian involved.

For adults with bulimia nervosa or binge eating disorder, CBT-E is my most frequent starting point, with DBT-derived skills woven in where emotion regulation is a prominent driver. For adults with anorexia nervosa or atypical anorexia, treatment usually integrates elements of MANTRA and CBT-E, sequenced to the person’s medical stability.

Alongside the eating-disorder-specific work, treatment addresses the common companion presentations — anxiety, depression, trauma, obsessional patterns, perfectionism, and shame. Where trauma is a driver, EMDR may be added once eating and physical stability are established. ACT contributes throughout — building willingness, values-based living, and a workable relationship with the difficult feelings that used to be numbed with food or restriction.

Recovery is not linear. I say this at the start so that setbacks — a rough week, a re-emergence of an old behaviour, a plateau — do not derail treatment. In my experience, setbacks are almost always information rather than failure, and used well they accelerate learning.

Multicultural context is important. In many South Asian and other cultural contexts, food is central to family, hospitality, ritual, and love. Eating disorders in these contexts often carry additional layers of secrecy, shame, and complicated family dynamics around food. Being able to work with a clinician who understands both the clinical picture and the cultural context — without minimising either — often removes barriers that have kept treatment inaccessible for years.

What Recovery Actually Looks Like

Recovery from an eating disorder is not the disappearance of every food-related thought. It is a gradual restoration of nutritional health, a loosening of the mental grip that food and body have held, and the return of energy for the things that matter. In practice, that often means:

• Eating regularly and adequately across the day, without ritualised rules
• Body weight in a range that supports full physical and cognitive function
• Menstrual return (where relevant) and normalised bloods and vitals
• The capacity to eat socially and flexibly without hours of anticipatory dread or later compensation
• Emotion regulation strategies that do not depend on food or its restriction
• A relationship with the body that includes respect and care — not necessarily love, but no longer war

Longitudinal follow-up studies find that the majority of people with anorexia and bulimia eventually reach full recovery, though the timeline is often measured in years rather than months (Eddy et al., 2017). Waiting to seek help until it “gets bad enough” adds years to recovery. Seeking help early — even when the disorder feels ego-syntonic — is one of the most protective decisions a person can make.

Common Companion Conditions

Eating disorders rarely arrive alone. In my clinical practice, I most often see them alongside:

• Anxiety disorders — particularly generalised anxiety, social anxiety, and OCD (see our page on anxiety treatment in Bella Vista)
• Depression — often reactive to years of malnutrition and shame
• Trauma — childhood adversity is a well-documented risk factor
• ADHD — particularly relevant to binge eating disorder
• Perfectionism and obsessive-compulsive features
• Substance use — sometimes as an alternative regulation strategy

Good eating disorder treatment holds these companion presentations together rather than treating them in isolation.

A Note for Families and Partners

The people around a person with an eating disorder often feel helpless — watching a loved one struggle with meals, noticing changes they cannot mention, worrying without a clear way to help. Some brief principles: avoid comments about weight, shape, or food quantity even when meant kindly; do not police meals unless this has been agreed as part of a treatment plan; do offer steady, non-judgemental presence and practical help with the practicalities of getting to appointments. Our guide to supporting a loved one with an eating disorder goes into this further. Where a spouse, parent, or close friend wants to be part of the treatment picture, that involvement can be genuinely useful and is planned collaboratively with the person and clinician.

Practical First Steps While You Book

Whether or not you end up in formal treatment, these steps are useful:

• Book your GP — for a physical review (weight, bloods, ECG where indicated) and a Mental Health Care Plan or Eating Disorder Plan referral. Under the Medicare Eating Disorder Plan, eligible people can access up to 40 psychological sessions and 20 dietetic sessions in a 12-month period.
• Eat regularly — three meals and two to three snacks across the day is the pattern most evidence-based protocols start with, even before formal treatment begins.
• Reduce diet-culture inputs — unfollow accounts that trigger food, weight, or body comparison. Notice how your mind changes over two weeks.
• Tell one trusted person — the secrecy of eating disorders is one of the biggest maintaining factors. Naming it to one person is often the hardest and most helpful early step.
• Contact the Butterfly Foundation — for free confidential support and information while you organise formal care.
• Approach your body with basic care — sleep, hydration, warmth. These sound trivial. They are not.
