Eating Disorders: Beyond Dieting — What They Actually Are and Who They Affect

Of everything I treat, eating disorders are among the most misunderstood — both by the public and, often, by the people living with one. Patients frequently tell me they didn't think their eating was "bad enough" to be a real problem, because they didn't match the image of an eating disorder they'd absorbed from media.

That image is wrong in almost every respect. This article covers what eating disorders actually are, who they affect, and what treatment that works actually involves.

What Counts as an Eating Disorder?

Eating disorders are serious illnesses marked by severe disturbances to a person's eating behaviours, often accompanied by fixation on weight, shape, and control over food intake.[2] The three most common presentations are:

• Anorexia nervosa: Severe restriction of food intake driven by an intense fear of gaining weight or a distorted body image, sometimes alongside binge-eating and purging episodes
• Bulimia nervosa: Recurrent episodes of binge eating followed by compensatory behaviours such as forced vomiting or laxative use
• Binge-eating disorder: Regularly losing control over eating and consuming unusually large amounts of food, without the compensatory behaviours seen in bulimia

These are described consistently across major clinical sources, including the National Institute of Mental Health.[2]

Who Do Eating Disorders Actually Affect?

An estimated 9% of the population will experience an eating disorder during their lifetime.[1] While these conditions remain more common among women and girls, men and boys make up a meaningful share of cases and are frequently underdiagnosed precisely because clinicians and family members are looking for a stereotype rather than the illness itself.

Eating disorders do not discriminate — they affect people of all ages, races, ethnicities and body sizes, and a person can be underweight, average weight, or overweight and still have a serious eating disorder.[3]

Why Are Eating Disorders So Dangerous?

Eating disorders often involve serious medical complications that can cause permanent damage or death, and people with eating disorders also face an increased risk of dying by suicide.[3] This is precisely why "just eat" or "just stop" is never an adequate response — the illness has taken over regulatory systems in the body and brain that willpower alone cannot override.

What Does Effective Treatment Involve?

• Medical stabilisation: Especially crucial when malnutrition or purging has caused physical complications — the first priority in more severe cases
• Nutritional rehabilitation: Structured, supported work with a dietitian to restore regular, adequate eating patterns
• Psychotherapy: Approaches such as cognitive behavioural therapy and family-based treatment (particularly for adolescents) directly target the thoughts and behaviours sustaining the disorder
• Medication: Not a primary treatment for most eating disorders on its own, but can help manage co-occurring depression, anxiety, or OCD that often accompany them

Because eating disorders sit at the intersection of psychiatric and physical health, care is most effective when a psychiatrist, dietitian and, where needed, physician work together rather than treating any one piece in isolation.
