Is the definition different between men and women, and adults and children?
For adults overweight and obesity ranges are determined by using weight and height to calculate a number called the “body mass index” (BMI). To find out more about BMI visit our BMI Calculator ยป BMI is still the most common method of defining overweight and obesity in children. However the definition is slightly different. Because when we are younger our BMI changes with age and differs between the sexes, special age and sex-specific charts called centile charts are needed for childhood and adolescence. Cut off levels are then used for defining overweight and obesity.
