Here’s something to think about. In one case, someone misses lunch during a stressful workday. A teenager avoids eating with friends because the food might not fit their rules. Both involve eating, but the reasons behind them and their impact may be very different. Are they disorders, problems, both, or something else?
The difference between eating problems and eating disorders is not simply what someone eats or how much they weigh. It involves the pattern of thoughts and behaviours, the effect on health and daily life, and whether the person meets the criteria for a clinical diagnosis. In other words: it is very complicated.
Not every eating difficulty is a disorder. At the same time, a person does not need a diagnosis before their concerns deserve attention. Consider anxiety: whether it is due to a specific situation or a diagnosis, both can require support.
Understanding the distinction should help people seek the right support, not convince them to wait until things get worse.
What are eating problems?
Eating problems is a broad, everyday term. Think of it as more of a transient or lower-level condition. It might describe reduced appetite, trouble maintaining regular meals, or difficulty eating certain foods. Allergies can fall into this. A person with a peanut allergy who is very hesitant to eat something likely does not have an eating disorder.
The phrase can also include serious problems; it does not tell us how mild or severe they are.
There can be many explanations. Grief, illness and some medications can affect appetite. Food allergies, cultural practices and limited access to food also need to be understood and considered.
Think about someone who loses their appetite after losing a close friend of family member. That does not automatically mean they have an eating disorder. It also does not mean their difficulty eating should be ignored, particularly if their health is affected.
Asking something like “Are they eating the same way as everyone else?” probably is the wrong place to start. And also can be harmful. I prefer the question: “Why are they eating the way that they do, and what support do they need and want?”
What is “disordered eating?”
Disordered eating describes troubling patterns of thoughts and behaviours around food, eating or body image. These may involve strict food rules, repeated restriction, distress about eating, or feeling out of control. The term describes a pattern; it is not a separate formal diagnosis.
The Canadian Psychological Association explains that disordered eating can cause distress and harm even when someone does not meet the criteria for an eating disorder.
Imagine an adult who starts avoiding meals with colleagues because they cannot control the menu. They spend much of the day thinking about food and feel guilty when plans change. The concern is not one meal. It is the anxiety, lack of flexibility and shrinking social life around it.
Disordered eating can occur with or without a diagnosed eating disorder. These are not fixed stages that everyone moves through. A diagnosis is also not a measure of whether someone has struggled enough to deserve help. In fact, it is better to help someone in need because they are in need. Not just because they can prove it.
What makes something an eating disorder?
An eating disorder is a recognized health condition with specific diagnostic criteria. A qualified clinician considers the person’s eating patterns, thoughts, physical health and daily functioning. Some diagnoses also have frequency or duration criteria, but those are not instructions to delay getting help.
(Full disclosure: our clinic when this article was written does not provide assessments nor diagnoses for disorders. We can help you find a licensed professional if you are in need).
Eating disorders can affect people of different ages, genders and body sizes. The better-known diagnoses do not all look the same:
Anorexia nervosa involves food restriction that leads to significantly low body weight. It also involves fear of weight gain or behaviours that prevent it, and difficulties with body image or recognizing the seriousness of the illness.
Bulimia nervosa involves repeated binge-eating episodes followed by behaviours intended to “undo” the eating or prevent weight gain. A binge involves both an unusually large amount of food in a limited period and a sense of losing control. It is not simply enjoying a large meal.
Binge-eating disorder involves repeated binge-eating episodes with significant distress, without the repeated attempts to “undo” the eating seen in bulimia. Calling it a lack of willpower misses the nature of the illness.
Avoidant/restrictive food intake disorder (ARFID) involves food avoidance or restriction that seriously affects nutrition, growth or daily life. It may relate to sensory sensitivities, low interest in food, or fear of choking or vomiting. Unlike anorexia, it is not driven by concerns about body shape or weight.
Other specified feeding or eating disorder (OSFED) describes serious eating-disorder symptoms that do not fit all the criteria for another diagnosis. One example is atypical anorexia, where a person has the other features of anorexia but is not at a low body weight. “Atypical” does not mean harmless.
NEDIC’s guide to eating disorders explains these and other presentations. No short description can replace an assessment.
Signs that an eating problem needs attention
Look beyond the plate. A growing concern may show up in thoughts, behaviour, relationships or physical health:
- Emotional changes: strong guilt after eating, fear around meals, or food and body concerns taking over the day.
- Behavioural changes: increasingly strict food “rules”, repeated loss of control, secrecy, or feeling compelled to “make up for” eating.
- Social changes: avoiding friends, family meals, school activities or work events because food is involved (or not involved).
- Physical changes: dizziness, ongoing fatigue, digestive problems, menstrual changes, or disrupted growth in children and teens.
These are reasons to seek assessment, not a checklist for diagnosing yourself. Other health conditions can cause similar changes. Someone may also feel that nothing is wrong even when their health is at risk.
Importantly, body size cannot tell you whether someone has an eating disorder or how medically unwell they are. The Canadian Paediatric Society warns that serious restrictive eating disorders can be missed in young people who are not underweight.
Why do eating disorders develop?
There is no single cause. Genetic vulnerability, anxiety, difficult experiences, social pressures and body-related stigma can interact. For some people, sensory differences or fear linked to eating are central. The combination is different for each person.
I think that under the heading of social pressures, we need to focus on social media. It has had a devastating impact on children and teens and I don’t think can be overstated.
Explanations such as “They just want attention” or “They only need more discipline” are not useful – they actually are quite mean and potentially harmful. Do not dismiss what you see.
Eating disorders are not choices, and telling someone to simply eat differently does not address the illness. You also cannot shame somebody into change.
What should you do if you are concerned?
For your own concerns, arrange an appointment with a family doctor or nurse practitioner. Describe what has changed, how you feel around food, and any physical symptoms. A clinician with eating-disorder expertise can help assess the problem and identify an appropriate treatment plan.
When you are worried about someone else, choose a private, calm moment rather than starting an argument over dinner. Focus on what you have noticed and how the person seems to be doing, not their appearance.
One way might be to say something like “Meals seem stressful lately, and you have stopped joining us for things you used to enjoy. I am concerned about how you are feeling. Do you want to talk about it?” Especially for teens, just letting them know that you are paying attention and are there for them is important.
Try to listen and avoid debating whether their body looks “fine.” Remember also that a first conversation may not resolve everything. NEDIC offers guidance on approaching someone with concern rather than criticism.
For children and teens, seek professional guidance even when they minimize the concern. Compassion does not mean waiting for them to agree that there is a problem. Parents may need an active role in care, including structured meal support guided by the treatment team.
At our clinic, we will often have parents reach out to us asking if we can help. The answer can vary. As a start, for teens, they need to provide their own consent for treatment. You might also need the help of a family doctor or nutritionist/dietician. We will do what we can to help you find the supports you need.
What does treatment involve?
If this was an easy question to answer, then likely the problem would be solved by now. Treatment may combine psychotherapy with medical monitoring and support from a registered dietitian with eating-disorder experience. In extreme or unique cases, a patient might need a more intensive program or hospital care.
For mental health support, a therapist can try to help a patient address fear, rigid beliefs, difficult emotions and behaviours that keep the problem going. Medical care assesses and treats physical complications. Nutritional care supports adequate nourishment. These roles work together; one does not automatically replace the others.
Family-based treatment is an established approach for many young people with restrictive eating disorders. It is a specific treatment, not simply general family counselling or advice to parents.
Remember: improvement can happen. It can be a process that is not linear and filled with frustrations. It can also be a process that is worth the effort.
Frequently asked questions
Can someone have an eating disorder without being underweight?
Yes. Eating disorders occur across body sizes. Neither appearance nor a single weight measurement can establish a diagnosis or rule out serious medical complications.
Is picky eating the same as ARFID?
No. Food preferences or sensory sensitivities alone do not establish ARFID. Assessment considers whether restricted eating causes significant nutritional, growth or daily-life problems, along with other possible explanations.
Can disordered eating be serious without a diagnosis?
Yes. A person can experience substantial distress or health risks without a formal diagnosis. Not having been assessed is also different from being assessed and not meeting diagnostic criteria.
How do I talk to my teenager about concerning eating habits?
Describe changes without blame, ask about their experience, and offer support. Avoid comments about weight or appearance. Arrange professional assessment when concerned rather than relying on reassurance that everything is fine.
Can someone recover from an eating disorder?
Yes. People can recover, including after a long struggle. The process differs between individuals and often involves coordinated support. Seeking help is worthwhile even when someone feels unsure about change.
