Restrictive Eating: Could It Be a Sign of Anorexia Nervosa?

Have you noticed your child eating less than usual, skipping meals or becoming increasingly worried about food/calories or their weight? Perhaps they have started avoiding certain foods, exercising more or expressing concerns about their weight or body shape.

These changes can be worrying for parents. While eating habits can change for many reasons, sometimes they may be signs of an eating disorder, such as anorexia nervosa.

What is restrictive eating?

Restrictive eating happens when a person limits the amount or type of food they eat. This may involve skipping meals, eating smaller portions, avoiding certain food groups or following strict food rules.

When there is an intentional drive for restriction and this restriction is linked to an intense fear of weight gain or behaviors aimed at preventing weight gain, it may be a sign of anorexia nervosa.

What are the signs parents should look out for?

Anorexia nervosa can develop gradually, and the signs are not always easy to recognize. Some possible changes include:

Eating less than usual: Your child may skip meals, leave food unfinished or say they are not hungry.
Increasing food rules: They may avoid foods they previously enjoyed, cut out food groups or become very concerned about calories, ingredients or portion sizes.
Worries about weight and body shape: They may frequently talk about their weight, feel that their body is not good enough or become afraid of gaining weight.
Changes in exercise: They may exercise excessively, feel guilty when they cannot exercise or struggle to take rest days.
Changes in mood and behavior: They may become more anxious, withdrawn, irritable or distressed around mealtimes.
Avoiding meals with others: They may make excuses not to eat with family or friends or become uncomfortable when others comment on their eating.

Some children may also experience dizziness, feeling cold, tiredness, difficulty concentrating or changes in growth and development.

Importantly, a child does not need to look underweight to have an eating disorder. Restrictive eating can affect physical health even when a person’s weight appears to be within the expected range.

How can parents help?

It can be frightening to notice these changes, especially if your child becomes defensive when you try to talk about food.

Try to approach the conversation with curiosity and compassion rather than focusing on weight or appearance. Let your child know that you are concerned about how they are feeling and want to help.

You can:

Encourage regular meals and snacks in line with professional guidance.
Avoid criticism, blame or comments about your child’s body.
Listen to their worries without dismissing them, even if they seem difficult to understand.
Seek professional support early, rather than waiting for the problem to become more severe.

If any of this feels familiar, don’t wait. Speak to your primary care doctor or an eating disorder service about an assessment, because the earlier a child gets support, the better the outlook. Univa’s programs are designed to meet families at whichever point they’ve reached: the restrictive eating program for children with early signs or suspected anorexia, and the anorexia program for children with a diagnosis. In both, parents and caregivers are supported every step of the way.

If your child is fainting, experiencing chest pain, becoming confused or showing signs of severe physical weakness, seek urgent medical help.

Does your child eat only a few foods? Do they become upset when you offer something new, or refuse to eat foods because of their smell, texture or appearance?

If this sounds familiar, you may have wondered whether your child is simply a picky eater or whether something else is happening.

One possibility is Avoidant/Restrictive Food Intake Disorder (ARFID).

What is ARFID?

ARFID is an eating disorder that affects the amount and/or variety of food a person eats. Unlike anorexia nervosa, it is not driven by a desire to lose weight or change body shape.

Children with ARFID may want to eat more foods but find it extremely difficult. Their eating difficulties are real and are not simply a choice or a behavioral choice.

What are the signs of ARFID?

ARFID can look different from one child to another. Some common signs include:

Eating a very limited range of foods: Your child may accept only a few familiar foods, brands or meals.
Sensory sensitivities: They may struggle with particular textures, smells, tastes, colors or food temperatures.
Fear of eating: They may worry about choking, vomiting, gagging or experiencing pain after eating.
Little interest in food: Eating may feel like a chore. Your child may rarely feel hungry or become full after eating only a small amount.
Anxiety at mealtimes: They may become distressed when new foods are offered or when familiar foods look different.
Avoiding social situations: Eating at school, birthday parties, restaurants or friends’ houses may feel overwhelming.

Over time, these difficulties can affect growth, nutritional health, energy levels and family life. Some children may also struggle to gain weight as expected.

Importantly, a child does not need to be underweight to experience ARFID.

How can parents help?

It can be worrying when your child eats very little or refuses most foods. You may feel frustrated, anxious or unsure what to do next.

Try to remember that your child is not giving you a hard time – this is not a choice, and they may be having a hard time themselves.

This is not your fault either.

You can help by:

Keeping mealtimes calm and predictable.
Avoiding pressure, threats or forcing your child to eat.
Continuing to offer familiar foods that help your child feel safe.
Introducing new foods gradually, without expecting your child to eat them straight away.
Seeking professional advice if you are concerned about their weight and growth

If you recognize these signs in your child, speak to your primary care doctor or a healthcare professional with experience in feeding difficulties and eating disorders. Early support can help you understand your child’s needs and find a way forward. Univa’s ARFID care program is designed for exactly this stage, offering early, specialist support for children with suspected or diagnosed ARFID, and for the parents and caregivers alongside them.
