What you should know about BMI?

Thursday 19th September 2013

BMI stands for Body Mass Index and is used to estimate a healthy body weight only based on your height and weight. The calculation is: Body Mass Index = Weight (kg) / Height2(m). However, this measurement does NOT actually estimate % body fat. The ranges that you typically read about are:

18.5-24 is considered to be a healthy range
25-29 is overweight
30+ is considered obese

BMI isn't a very accurate way to diagnose individuals' health but rather it was designed to compare and classify populations of people. The BMI calculated for tall, slender people usually indicates they have more body fat than they actually do (just because of the way BMI is calculated).

BMI also doesn't take into consideration the difference in weight of muscle and fat. Therefore someone who is very muscular could end up having a very high BMI (indicating they are overweight) when really the extra weight is due to muscle mass, not fat. And the muscle mass is a positive thing.

BMI doesn't account for differences in frame size, fat proportion, bone densities and age - all factors that can affect an individual's body weight. It's important to monitor your health and the changes in your BMI are more important that the actual number.

It is just a number that should be monitored as you age, your metabolism changes, your acitivity levels change and in conjunction with various other health factors that are important as an overall indicator of your wellbeing.
