Childhood obesity is when children have too much body fat. This means there’s a risk to their health. A healthy family lifestyle has lots of benefits for children’s health and wellbeing and can help children avoid childhood obesity.

About childhood obesity

Overweight and childhood obesity are terms you might hear when children have an excessive or abnormal amount of body fat that presents a risk to their health.

This can happen when the energy children get from food and drinks is greater than the energy they burn up through physical activity, growing and other body processes. This extra energy gets stored as fat.

Some children are also at greater risk of obesity because of genetic factors that make their bodies gain weight more easily.

Overweight and obesity are significant issues for some children. If you help children deal with these issues during childhood, they’re less likely to have problems with overweight and obesity later in life

Helping your child maintain a healthy weight

Many factors can put children at a higher risk of becoming overweight and obese. These factors include:

  • unhealthy food and drink choices
  • unhealthy family habits
  • lack of physical activity
  • family genetic history
  • other environmental factors.

You can help your child maintain a healthy weight by looking at how these factors shape your family’s lifestyle.

Food choices
If you give your child a range of healthy nutritious food, it will help your child grow and develop in a healthy way. Your child will also be less likely to gain too much body fat.

Healthy nutritious foods include vegetables, fruits, grains, reduced-fat dairy, meat, fish, chicken, eggs and legumes such as peas, beans and lentils.

Tap water and milk are the healthiest drinks for children.

Physical activity
You can encourage your child to be physically active by walking when possible and playing outdoors. Physical activity will:

  • balance your child’s energy intake
  • control your child’s appetite
  • decrease your child’s stress
  • prevent disease
  • increase social interactions.

All these things are part of an overall healthy lifestyle for your child. 

Family habits
Your child is more likely to make healthy food choices and be active if she sees you eating healthily and being active. Young children do as you do, so modelling healthy eating and regular exercise can have a big impact.

Family genetic history and other factors
Everyone comes in different shapes and sizes, partly because of lifestyle, but also because of genes.

Some children are at greater risk of obesity because of their genes, or because they have health problems or take medication. If you have any of these factors in your family, it’s even more important for you all to make healthy food and lifestyle choices.

Other factors
Screen time, busy family lifestyles, lack of outdoor space – all these things can make it easy for children to overeat and harder for them to be active. It can be tough, but there are ways to overcome obstacles to physical activity.

Another risk factor for childhood obesity is sleep. Children who don’t get enough sleep at night are more likely to become overweight or obese. Promoting good sleep for children is an important part of helping them to develop healthy habits.

Getting your child into healthy fresh food and physical activity early in life can help reduce your child’s risk of overweight issues or obesity in the future. Our healthy food videos shows you how to make healthy food quick, easy and fun.

Why your child needs to maintain a healthy weight

Maintaining a healthy weight is important to your child’s health now and in the future. A healthy weight now reduces your child’s chances of:

When we identify and manage overweight problems and childhood obesity early, it gives children a better chance of avoiding long-term weight problems that can lead to serious consequences for their health and wellbeing.

Worried about weight or childhood obesity: what to do

If you’re worried that your child might have a weight problem or even childhood obesity, it’s important to start with a proper assessment.

A GP, paediatrician or dietitian can look at your child’s growth and work out whether he has a healthy weight. The health professional might look at your child’s height, weight and body mass index (BMI). BMI is one way of adding up total body fat and working out whether your child’s weight is within a healthy average range.

If your child is overweight, you can make many small and realistic lifestyle changes to help your child. If you involve the whole family in these changes, it’s easier for your child to stick with the changes – and it’s good for everyone.

Here are simple changes you can make to everyday family eating:

  • Involve your children in choosing and preparing healthy foods for meals. This helps them learn about healthy foods and making good choices. They’re also more likely to eat something they’ve helped to make.
  • Get your child drinking water, and keep soft drink, juices, cordials, sports drinks, flavoured waters and flavoured milks out of the house.
  • Eat more vegetables and salad. Aim to fill half the plate at main meals with salad or vegetables.
  • Keep ‘sometimes’ foods such as fast food, potato chips, biscuits, cakes and chocolates out of the house. If you don’t have them at home, it’s harder for your child to eat them.
  • Set a good example, and show your child that you enjoy healthy eating yourself.
  • Establish regular mealtimes, including breakfast, and sit down to enjoy meals together as a family – with the TV switched off.
  • Eat most meals at home. At home you can limit the amount of fat, salt and sugar in your meal.
  • Have healthy snacks handy for when you know your child will be hungry. For example, keep a bowl of fresh fruit on the bench and a container of vegie sticks in the fridge.
  • Don’t force your child to eat. You don’t need to worry if your child refuses to eat or eats very little. Your child won’t starve.

Here are simple changes you can make to get more physical activity into your family’s life:

  • Restrict screen time to no more than two hours a day for children aged 5-18 years. Screen time includes TV, DVDs, computers, video games, mobiles phones and tablets.
  • Give your child the chance for active play. Your child needs at least one hour a day of physical activity.
  • Build activity into everyday family life – for example, go for family walks or bike rides together.
  • Walk to and from school, the local shops or friends’ places if possible.
Everyone with overweight problems needs support to lose weight. Your child can’t do it without you. If the whole family makes healthy food choices and gets active, it’s easier for your child to keep going with healthy lifestyle changes.

Talking about healthy weight and childhood obesity

Childhood obesity is a sensitive issue.

If your child does have an overweight problem, it’s better not to label her as overweight or obese. Instead you can talk about what your family needs to change to help your child get to a healthy weight.

Here are tips for talking with your child about overweight and obesity:

  • Focus on health and healthy lifestyle rather than weight loss. It can be hard for children to lose weight.
  • Try to use terms such as ‘above average weight’ or ‘above a healthy weight’ rather than labels such as ‘fat’, ‘good’, ‘bad’, ‘chunky’ or ‘obese’.
  • Praise and encourage qualities that aren’t about the way your child looks. For example, ‘I like the way you handled that big school assignment’, ‘I feel proud when you look after the younger kids so well’ and ‘It’s great that you were calm before your talk’.
  • Try to avoid saying things like ‘Don’t you think you should …’ or ‘You shouldn’t be having that’. Children might feel you’re nagging and could be less likely to do what you want.
