Better Health and Childhood Obesity: Supporting Children to Thrive

Helping children achieve better health is about much more than the number on a scale. It means supporting their physical and emotional wellbeing, building healthy habits and making it easier for families to access nutritious food, enjoyable activity and good-quality sleep.

Childhood obesity is influenced by many factors, including biology, family circumstances, income, food environments, advertising, sleep and opportunities to be active. It is not a sign that a child or parent has failed. A compassionate, whole-family approach can help improve health without blame or shame.

Look beyond weight

A child’s growth should be considered in the context of their age, development and overall health. In the UK, health professionals may use a child’s height and weight plotted on a growth chart to understand their growth pattern. These measurements are only one part of an assessment; a GP, health visitor or school nurse can help interpret them and discuss any concerns.

Children grow at different rates, and weight changes can be sensitive. Conversations are best handled privately and respectfully, focusing on health, energy, confidence and wellbeing rather than appearance. Avoid teasing, comparisons or restrictive diets, which can harm a child’s relationship with food and their body.

Build healthy routines together

Small, realistic changes can make a difference when they become part of everyday family life. Parents and carers can help by offering regular meals and snacks, keeping a variety of foods available and encouraging children to try new tastes without pressure. Fruit and vegetables, wholegrain foods, beans, pulses and other sources of protein can all contribute to a balanced diet. Water and plain milk are generally better everyday choices than sugary drinks.

There is no need to label foods as “good” or “bad”. A flexible approach helps children enjoy food while learning what supports their health. Eating together when possible, involving children in choosing or preparing meals, and keeping mealtimes relaxed can also encourage positive habits.

Make movement enjoyable

Physical activity supports children’s fitness, strength, mood and sleep. It does not have to mean organised sport: walking, cycling, dancing, active play, swimming and helping with household tasks can all get children moving. Choose activities that suit the child’s interests and abilities, and where possible make them something the whole family can enjoy.

Reducing long periods of sitting and balancing screen time with sleep, play and other activities may also help. The aim is not to punish or exhaust a child, but to make movement a normal and enjoyable part of the day.

Sleep and emotional wellbeing matter

Regular sleep routines support children’s development and can make it easier to manage appetite, mood and concentration. A calm bedtime routine and consistent sleep and wake times may help. If a child is persistently tired, snores heavily or has difficulty sleeping, speak to a health professional.

Children also need to feel safe, valued and accepted. Stress, bullying, low mood and anxiety can affect health and everyday habits. Listen without judgement, take concerns seriously and seek support if a child’s wellbeing is affected.

Families and communities can make change easier

Healthy choices are easier when they are practical and affordable. Schools, local services, food providers and policymakers all have a role in creating environments where children can eat well and be active. Safe parks, walking routes, inclusive sports and accessible health services can make a real difference—especially for families facing financial or other barriers.

When to seek advice

If you are worried about a child’s growth, eating, activity, sleep or emotional wellbeing, contact your GP, health visitor or school nurse. They can offer confidential advice and, if appropriate, discuss further support. Avoid putting a child on a weight-loss diet unless this is recommended and supported by a qualified health professional.

Better health is built through supportive relationships and sustainable habits, not quick fixes. By focusing on wellbeing, making healthy routines enjoyable and seeking help when needed, families and communities can help children grow with confidence.

What is childhood obesity, and how is it assessed in the UK?

Childhood obesity describes excess body fat that may affect a child’s health and wellbeing, but it cannot be judged reliably by appearance alone. In the UK, health professionals usually assess a child’s growth by measuring their height and weight, calculating their body mass index (BMI) and plotting it on an age- and sex-specific growth chart, such as the UK-WHO chart. The result is considered alongside the child’s growth pattern, development and wider health; it is a screening measure, not a diagnosis on its own. A GP, health visitor or school nurse can explain the results and discuss any concerns sensitively.

What health problems can childhood obesity cause?

Childhood obesity can increase the risk of health problems such as type 2 diabetes, high blood pressure, raised cholesterol, joint pain, breathing difficulties and fatty liver disease. It may also affect sleep and emotional wellbeing, and some children experience low self-esteem or bullying. These risks vary from child to child, and having a higher weight does not mean a child will necessarily develop health problems. If you are concerned about a child’s health or growth, speak with a GP, health visitor or school nurse for supportive, personalised advice.

How can I tell whether my child’s weight is affecting their health?

A child’s weight is only one part of their overall health, and appearance alone cannot show whether it is causing a problem. Look at their growth over time, energy, mobility, sleep, mood and general wellbeing, but avoid drawing conclusions from these signs or commenting negatively on their body. If you have concerns, speak privately with your GP, health visitor or school nurse, who can assess your child’s growth using age-appropriate charts and discuss any related health issues sensitively.

What should my child eat for a healthy, balanced diet?

A healthy, balanced diet for your child should include a variety of foods: plenty of fruit and vegetables, starchy foods such as potatoes, bread, rice or pasta (wholegrain options where possible), and protein sources such as beans, lentils, eggs, fish or lean meat. Include milk or other dairy foods, or suitable alternatives, and offer water as the main drink. Aim for regular meals and snacks, and let your child’s appetite guide how much they eat. There’s no need to ban particular foods; keeping treats occasional and focusing on enjoyable, varied meals can help build healthy habits. If you have concerns about your child’s growth or diet, speak to your GP, health visitor or school nurse.

How much physical activity should children get each day?

Children and young people aged 5 to 18 should aim for an average of at least 60 minutes of moderate to vigorous physical activity each day across the week. This can include brisk walking, cycling, active play, dancing or sport, and it does not need to happen all at once. Activities that strengthen muscles and bones, such as climbing, jumping or running, should be included regularly. Younger children should also have plenty of opportunities to move and play throughout the day. Choose enjoyable activities suited to your child’s age and abilities, and speak to a health professional if you have concerns about what is appropriate.

How can I help my child develop healthy habits without focusing on weight?

Help your child build healthy habits by making them a positive part of family life, rather than linking them to weight or appearance. Offer a variety of nourishing foods, enjoy regular meals together, keep water readily available and encourage your child to help choose or prepare food. Make movement fun by finding activities they enjoy, such as walking, dancing, cycling or active play, and support a calming bedtime routine. Focus on how these habits can help everyone feel energised, sleep well and enjoy daily life. Avoid criticism, comparisons or restrictive diets, and speak with your GP, health visitor or school nurse if you have concerns about your child’s health or development.

How can sleep and screen time affect a child’s health and weight?

Sleep and screen time can influence a child’s health, mood and everyday routines. Too little or disrupted sleep may affect energy, appetite and the motivation to be active, while long periods on screens can replace time spent sleeping, moving or playing. Screen use can also expose children to food advertising, and using devices close to bedtime may make it harder to settle. A regular bedtime routine, keeping screens out of the bedroom overnight and balancing screen use with active play can help support healthy habits. The right approach will vary by age and family circumstances; speak to a GP or health visitor if you are concerned about your child’s sleep or wellbeing.

Where can families in the UK get support for childhood obesity?

Families concerned about a child’s weight or health can speak to their GP, health visitor or school nurse, who can offer confidential advice and, where appropriate, refer them to local NHS services or a family-based healthy weight programme. Some areas also provide support through children’s centres, schools, local councils and community organisations. Services vary across the UK, so ask your healthcare professional or local council what is available nearby. Support should be respectful and focused on the child’s overall wellbeing, not blame or stigma.

When should I speak to a GP, health visitor or school nurse about my child’s weight?

Speak to your GP, health visitor or school nurse if you’re concerned about your child’s growth, weight, eating habits, activity levels or wellbeing. You don’t need to wait until a problem seems serious: a health professional can review your child’s growth over time, discuss any changes sensitively and suggest practical support for the whole family. Seek advice sooner if your child is being bullied, feeling distressed about their body, experiencing rapid weight change or having symptoms that worry you.
