Why talking to your child about obesity matters
Talking about weight and health with your child can feel challenging, especially given the confusing messages they encounter through social media, at school, and in the wider society.
As a parent or caregiver, you play an important role in helping your child understand these messages in a supportive, positive way. By creating a safe space for discussing obesity in children, you can help your child feel understood, supported, and more confident in talking about their health and wellbeing.
When should you talk to your child about weight?
You don’t need to plan one serious “big talk” about weight and health. Often, it can be better to have short, relaxed conversations when the topic comes up naturally. Everyday moments, such as cooking together, shopping, or going for a walk, can create opportunities to talk about weight and wellbeing comfortably.
When talking with your child, try asking open-ended questions rather than questions that can be answered with a simple “yes” or “no”. This can help your child feel more comfortable sharing their thoughts and feelings.
What to say (and what not to say) to your child
Even playful comments or jokes about body size can hurt a child’s confidence and body image. Drawing comparisons between siblings, peers, or family members might similarly negatively affect your child, regardless of your intentions. Criticism and negative comments about weight or appearance can also impact your child.
Where possible, try to avoid focusing conversations on strict diets, calorie counting, or pressure to lose weight, as these discussions can affect a child’s relationship with food and may contribute to eating disorders in children.
Rather than imposing guilt or pressure on your child, prioritising phrases that promote healthy habits can help them feel secure. Focus on positive encouragement around food, movement, and self-esteem, instead of centering conversations only on weight. You can use positive phrases such as:
“Your body gets stronger when you play, move, and rest.”
“Eating a variety of foods helps your body grow and learn.”
It is also helpful to use language that does not label different body shapes and sizes, as this will show your child that all bodies are worthy of respect.
| Instead of saying… | Use these phrases: |
|---|---|
| You are fat/too big. | How do you feel about your body? |
| You need to lose weight. | Would you like to talk about your health or any goals you have? |
| Stop eating so much. | How does your body feel when you eat that amount? |
| You should go on a diet. | Are there any healthy habits you’d like support with? |
| Your weight is unhealthy/wrong. | Your health is about many things. Is there anything you’re concerned about or would like to discuss? |
Many of these small changes can help you create an environment where your child feels comfortable talking about weight, health, and wellbeing.
Remember: The goal of talking about weight is not the number on the scale; it’s to help your child build healthy habits and confidence.
When you talk about weight, centre the discussion on health, energy, growth, strength, and wellbeing rather than body size or appearance to create a positive, supportive environment.
Celebrating what bodies can do rather than how they look can even increase your child’s confidence.
Weight-related teasing is a difficult experience. If your child faces this, create space for open, supportive conversations. This will help your child feel heard and understood, which helps them process their emotions.
You can also explain to your child that body size does not define a child’s worth, personality, intelligence, or happiness. This can help your child build confidence and self-esteem, while reinforcing that a person’s value is not defined by their appearance or body size.
Many children are exposed to different media daily, which can impact their body image. Unrealistic body ideals can affect how children feel about their bodies and may contribute to body dissatisfaction, which can increase the risk of eating disorders in children and teenagers.
Talk with your child about the images they see online, on social media, and on television. You play an important role in helping your child understand that lighting, makeup, filters, and photo editing are often used to alter people’s appearance, so images may not reflect how someone looks in real life.
To start a conversation about photo and video editing, you can use phrases like:
“That picture looks like it may have been edited. What do you think might have been changed to make it look that way?”
Creating healthy habits as a family
Rather than singling out one child, try making healthy lifestyle changes together as a family. Building healthy habits is a shared effort and can create a supportive, positive environment where every family member feels included.
Move away from strict or stressful routines to build lasting habits. Children are more likely to embrace and continue new habits they genuinely enjoy.
There are many fun activities that you can do together as a family. Whether it is dancing, outdoor games, family walks and cycles, or cooking a healthy meal together, try to focus on new healthy routines that are enjoyable and rewarding – for the whole family.
For inspiration, you can explore NHS resources below, which offer general nutrition information, healthy recipes, and exercise recommendations for children aged under 5, as well as those aged 5-18.
Children are more likely to engage with and maintain healthy habits when they feel involved in the decision-making process. Giving your child choices where possible will not only keep them motivated but also boost their confidence in making positive decisions.
A simple way to do this is by letting your child make choices around meals, snacks, and physical activities. You can also involve your child in meal planning, shopping, or choosing weekend family activities.
Building a positive support network around your child
Children often benefit from consistency; when parents, grandparents, caregivers, teachers, and other trusted adults all use the same approach to health and wellbeing, your child will feel secure and well supported. Children especially benefit when the adults around them model healthy habits and respectful conversations.
As a family, you can agree to use positive, respectful language and avoid criticism, teasing, or negative comments about body size, weight, or appearance.
Communication from school about your child’s weight can sometimes raise questions or concerns, but it may also provide an opportunity to start a supportive conversation.
If your child’s school shares information about their weight, you can start a conversation with your child by simply asking them how they feel about it. Listen to any concerns they may have, and reassure them that weight is something that you can discuss together openly and without judgment.
It is important to work as a team with your child, school, and other sources of support to improve your child’s health, wellbeing, and positive daily routines.
You can use the NHS BMI Calculator for children and teenagers to check if your child has a healthy weight and access further advice about possible next steps.
What to do if you struggle with your own weight
Many parents have personal experiences or insecurities related to weight and body image. Try to avoid negative self-talk about your own body in front of your child.
Children look up to their parents. By modeling positive routines and positive language around food and movement, you can help your child feel more confident and supported and create a nurturing environment. Focus on general health, energy, and wellbeing rather than dieting or appearance goals.
Remember that you don’t need to be perfect to support your child.
