Childhood obesity (Blog)
You may find it difficult to tell whether your child has temporary "puppy fat" or is genuinely overweight. In adults, a simple formula (the body mass index, or BMI) is used to work out whether a person is the right weight for their height.
However, BMI alone is not an appropriate measure for children, because they are still growing. Factors such as rate of growth, age and sex, and the BMI of other children of the same age must be taken into account when assessing your child's weight. BMI is best interpreted with the help of your GP, health visitor, practice nurse or dietitian.
