The graphic that shows why BMI is useless
The graphic, by New York-based Body Labs, shows full-body scans of six people with the same BMI but different body shapes. Each of the volunteers was 5 feet 9 inches tall and 172lbs (78kg).
The same BMI can look different on different people because muscle and bone are denser than fat. Some people carry more or less weight in their legs, but because BMI only considers height and weight, it overlooks these factors. The number labeled V is the amount of fluid that would fill a container the same size as the person's body in litres.
