  • Is The BMI A Good Health Indicator? More Than 1 Reason It Is!
November 14, 2021

The relevancy of the BMI as a good health indicator is a recurrent topic in the health and fitness industry. The BMI (Body Mass Index) is undoubtedly a widespread health indicator. But what does the result of your BMI tell you? Is it accurate? Can the BMI results be trusted? Many health professionals use BMI, but some experts say that it doesn’t provide an accurate picture. We’ll explore these questions and more in this blog post!

What Is The BMI? What Does The BMI Tell Me?

The Body mass index (BMI) is an approximate measure of your total body fat. The BMI result indirectly tells you what your best weight for health is.

What Is The BMI Formula?

The original BMI formula is weight in kilograms (kg) divided by height in meters squared (m)² as follow:

Metric-System BMI formula: BMI = Weight (kg) / Height (m)²

As a BMI formula example, a 60kg 165cm person has a BMI of 60/(1.65)^2=22.

Please note that the original Metric-System BMI formula uses meters and not cm when taking into account height. With the Imperial system, the original BMI formula is adjusted by a factor for weight and tall conversion purposes.

Imperial-System BMI formula: BMI = 703 * Weight (lbs) / Height (inches)²

As a BMI formula example using the imperial system, a 134lbs 64inch person has a BMI of 703 * 134 / 64² = 23.

Do Doctors Still Use Bmi?

Yes, they do. Doctors use BMI to assess a patient’s risk for obesity-related diseases and conditions, such as diabetes. Medical professionals know that the Body Mass Index must be interpreted within an adjusted BMI benchmark for some ethnicities to yield good insight into an individual’s health. Further adjustments are also required when the individual is very short or very tall or has an above-average proportion of muscle bulk.

Still, some people fail to do so and draw the wrong conclusion from the BMI result. A a result, the metric has been questioned due to its lack of accuracy in some cases.

Can The BMI Be Trusted?

Yes, the BMI is a trustworthy health indicator as long as the BMI result is interpreted correctly and adjusted for context. To draw the correct conclusion from a BMI calculation, it is essential to compare the BMI result with an ethnicity-adjusted BMI benchmark. For example, a BMI of 18 would be considered unhealthy in many situations, but it is a perfectly normal BMI for an Asian woman.

How Accurate Is The Bmi Calculator?

The accuracy of the BMI result is as good as its input data accuracy, weight, and height as the BMI calculator uses the Body Mass Index formula straightforwardly to get your BMI result. However, the interpretation of your BMI result is subject to variation. The correct interpretation of the BMI result is the key to making the BMI a good health indicator.

Is The Bmi A Good Health Indicator?

There has been much debate about the trustworthiness of BMI as an indicator for overall fitness or even weight. The truth is that the BMI calculation itself is not directly a good health indicator; but a correct interpretation of the BMI value adjusted for context (Height, ethnicity..) makes the BMI a good health indicator that is worth tracking. Calculate your BMI now!
