# What is BMI?

BMI stands for body mass index. Below is a small diagram illustrating the various BMI levels, but in essence it measures body fat against height and weight. Thereby, giving you a number. This number gauges if you have too much fat, health amounts, or too little fat. Given below is the gauge followed by the chart.

## BMI Categories:

Underweight = <18.5

Normal weight = 18.5–24.9

Overweight = 25–29.9

Obesity = BMI of 30 or greater

If you would like to calculate BMI for yourself, just type in the word “BMI” into Google and it will give you a calculator.

In most cases, an accurate BMI reading will give you an idea of how healthy you are. But not everything you read about BMIs in magazines is accurate. For example, let’s take a look at a very popular media figure. Dwayne "The Rock" Johnson.

Why him? Well, let’s look at the data. According to a quick search engine lookup The Rock stands at 196 cm and 110 kilograms of weight. This puts him at a BMI of 28.6. Looking at the scale above you can see The Rock is technically obese.

## The Rock is Obese?

But is he? This is where media magazines won’t call The Rock obese. The thing is that they can’t, The Rock is lean and shredded. Being overweight is based on the assumption of body fat. BMI does differentiate between fat and muscle. And The Rock is packed with muscle.

It does not matter about weight, for example 1 lb of fat weighs the same as 1 lb of muscle, but fat has a larger volume. Muscle is denser, you can have a lot more muscle on your frame than fat can accommodate. And this is where The Rock lies, as mentioned above, he is filled to the brim with lean muscle. This means that even though he weighs more than recommended for his height, his added weight is muscle and not fat. A BMI reading will not give you this information.

In addition, a BMI does not take into account a diet regime, workout plan or daily nutritional levels. In fact you may even deviate from a healthy BMI because you drank too much water and had a little extra salt in your food when you took a reading. And this might simply be due to extra water retention, not body fat.

## Conclusion

Therefore, it is important to understand that even though a BMI is a healthy benchmark to guide your progress, everyone is unique and there is no one size fits all when it comes to our bodies.
