Early Signs of Eating Disorders in Children: A Guide for Parents

Recognising the early signs of eating disorders in children can feel overwhelming for any parent.

In a world where societal pressures and unrealistic body ideals can feel greater than ever, it’s natural to be unsure of what to look out for. Many eating disorder behaviours — such as excessive exercise or restrictive eating — hide in plain sight, and are often even praised.

This guide is here to help. Below, we explain the early warning signs of an eating disorder in children and teenagers, and share practical, compassionate tips parents can use to support a healthy relationship with food and body image at home.

What are the early warning signs of an eating disorder

in a child?

No single sign confirms an eating disorder, but a cluster of changes is worth paying attention to.

Here are five areas to keep an eye on.

Changes in eating habits

As a parent, paying attention to shifts in your child’s eating patterns is one of the most important things you can do. Look out for sudden changes in appetite, increasingly rigid or extreme dieting, or your child eating noticeably more or less than usual. These shifts can be an early indicator that their relationship with food is changing.

Body image concerns

Pay attention to how your child talks about their body. Negative comments about their appearance, or a growing preoccupation with weight, can be early indicators of body image struggles. Encourage open conversations about self-esteem, and help your child see their body as something to care for rather than criticise.

Social withdrawal and isolation

Eating difficulties can often lead to social withdrawal. If your child begins to isolate themselves from friends or family around mealtimes, or starts avoiding social gatherings altogether, it may signal discomfort in food-related situations. A noticeable change in their mood or behaviour can be an early warning sign too.

Changes in exercise patterns

Regular, enjoyable movement is important for all of us — but obsessive or compulsive exercise can be a red flag. If your child becomes intensely focused on exercising to ‘make up for’ eating, or distressed when they can’t exercise, it may point to an emerging problem. You might notice they feel they ‘have to’ work out nearly every day for long periods, or that they’ll skip a social occasion rather than miss a session.

Emotional changes

Emotional well-being and eating are closely linked. Be attentive to signs of anxiety, low mood, or mood swings. Emotional distress can sometimes show up as an unhealthy relationship with food, used as a way of coping.

Early detection and support are key when it comes to eating difficulties in children. By staying attuned to changes in eating habits, body image, social behaviour, exercise, and emotional well-being, parents can play a vital role in protecting their child’s mental and physical health.

How parents can help

Here are three practical ways to approach eating and body image concerns with sensitivity and care.

Cultivate open communication and curiosity

Create a safe, non-judgemental space where your child feels comfortable talking about their thoughts and feelings about food and body image. Start conversations regularly, leading with genuine interest and concern. Ask questions and stay curious, rather than jumping in to ‘fix’ things — a very understandable impulse for most parents! Try to avoid blame or accusatory language, and focus instead on keeping the dialogue supportive and open.

Create a positive environment around food

Children often model their parents’ behaviour — they do as we do, not as we say. Aim to be a positive role model around food, showing a balanced and varied approach to eating. Avoid attaching moral value to food (for example, calling it ‘good’ or ‘bad’), and notice how you speak about your own eating — a throwaway ‘oh, I’ve been so bad today, I had pizza’ sends a powerful message. Make shared family meals a regular, enjoyable part of your routine where you can; they’re a chance to connect and build positive associations with food. Keep the atmosphere relaxed, let conversation flow, and focus on enjoying each other’s company.

Promote a healthy body image

Encourage a positive body image by emphasising self-acceptance and self-compassion. Counter societal pressure by celebrating difference and reinforcing that every body is worthy of respect and care. Model healthy attitudes by focusing on overall well-being rather than unrealistic appearance ideals. Show your child what it looks like to move your body for fun and joy — and get in the photo, get in the swimsuit!

When to seek professional support

If you’re concerned about your child’s changing relationship with food and/or exercise, trust your instincts and reach out. Speak to your GP, or a qualified professional trained in eating disorders, such as a dietitian or psychologist. Early support can make a real difference — you don’t need to have all the answers before asking for help.
