What is the new body mass index?

For nearly 200 years now, medical professionals the world over have used the universally accepted Body Mass Index (BMI) to help assess the overall state of a person’s health.

Experts have identified a flaw in the basic BMI formula and have recently come up with a new calculation which presents a more realistic result as it scales more accurately in relation to a person’s height.

The new, more honest method of calculating BMI is based on an equation developed by a British mathematician, which makes shorter people appear heavier and taller people slimmer. The new method takes better account of distortion caused by height.
