The Fallacy Of The Body Mass Index

Do you know what your BMI is?

If so, are you considered healthy? Overweight? Underweight?

The Body Mass Index (BMI) is supposed to tell you whether or not you are considered healthy. It is determined by the comparison between your weight and height (BMI = weight(kg)/height(m)2).

Simply divide the numbers and you have your BMI.

To this day it’s one of the screening tools doctors use to determine if an individual is healthy.

Unfortunately, it’s not really the best predictor of overall health…

The BMI does not take into account healthy muscle mass or body fat percentage (two very important aspects of optimal health)

Therefore, you might have a large amount of muscle mass and be considered overweight/obese.

If that’s the case, you could reasonably say that the BMI doesn’t make much sense.

We at Arizona Training Lab would agree.

The best advice we could give you is to focus on lean muscle mass. Your goal, year in and year out, should be to increase strength, build muscle, and reduce body fat.

This can be measured through a bod pod, dexa scan or calipers and it provides you a great starting point. Even better, it can be retested to show your progress and improvements.

You must remember, fat loss and weight loss aren’t always linear. You will have ups and downs but having accurate measurements is vital for your success and motivation.

If you need some starting points, let us know and we can help you out.
