Overweight and obesity levels in the UK have risen rapidly in recent years. It's said on the department of health website that nearly 1 in 4 adults and over 1 in 10 children aged 2 - 10, are obese.
What is Overweight and obesity? This is how the World Health Organisation (WHO) answers that question.
"Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health.
Body Mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person's weight in kilograms divided by the square of his height in meters (kg/m2).
The WHO definition is: 1. a BMI greater than or equal to 25 is overweight. 2, a BMI greater than or equal to 30 is obesity.
BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults. However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals."
