What is obesity?
'Obesity' and being 'obese' are words used by doctors to describe when a person (adult or child) is overweight to the extent that they are more likely to suffer health problems than a person who is a healthy weight.
The number of overweight and obese children in the UK has risen steadily over the past 20 years. It is estimated that up to 15 percent of children in the UK are overweight or obese. It's now a major health concern.
How children become obese
Children have high energy requirements because they are growing. A varied and nutritious diet is essential for their development. However, like adults, if they take in more energy in the form of food than they use up, the extra energy is stored in their bodies as fat.
