A new way of calculating Body Mass Index (BMI) has been proposed - but does it really solve any of the BMI's well-known problems?
How often have we heard that Brad Pitt at the time of Fight Club, and England rugby player Jonny Wilkinson in his prime, were "overweight" - according to their BMI?
Any system that tells people whether they are "normal", "underweight", "overweight" or "obese" is bound to be controversial, but one obvious weakness of the BMI is that it doesn't distinguish between fat and muscle.
First devised by Adolphe Quetelet more than 150 years ago, BMI is calculated by taking your weight (in kilograms) and dividing it by your height squared (in metres).
In simple terms, it is a way to compare the weights of groups of people of different heights.
