**What is Body Mass Index?**

It is determined by dividing the weight by the square of the height to get the BMI. Height is measured in meters and weight is measured in kilos. The term is referred to as BMI. It is also referred to as BMI and Body Mass Index. **It is a formula that is used to determine a person’s optimal weight and the weight category he falls into. **However, it could not produce a good result, particularly for individuals who are interested in bodybuilding, because it does not provide specific information regarding body fat and muscle mass.

**Because they have too much muscle mass, calculations based solely on height and weight can result in high BMI results.** Furthermore, the body mass index does not show the high fat ratio of an aged individual who has lost muscular mass.

**How to Calculate Body Mass Index?**

**Body mass index**, or BMI, is determined by dividing a person’s weight by height squared. The result of dividing your weight by the square of your height is calculated within the World Health Organization’s reference range. If the outcome is above 30, morbidly obese if it is over 40, and super fat if it is over 50, it is deemed obese.

The only factors used to determine the body mass index are weight and height. However, when calculating the detailed body mass index, factors like age, gender, body fat percentage, and waist circumference are also included.** Because the body mass index is calculated, people who have an excessive amount of body fat that will harm their health can compute these numbers under the guidance of a professional and get them to the right level for them.**

**How to Calculate Obesity?**

Today, there are various ways to determine the severity of the obesity condition. **Body mass index, or BMI, is the technique among these that is most user-friendly. The formula for calculating it involves multiplying a person’s weight by the square of their height in meters.** It is also known as the BMI (BMI). The following is an illustration of how the approach would be calculated using the World Health Organization’s classification of obesity:

- Let the calculation be made for a person who is 100 kilos and 1.80 m tall.
- For 1.8×1.8, the square of the neck is calculated as 3.24.
- The result of 100/3.24 is 30.8.
- When the reference ranges of the World Health Organization are evaluated, since results above 30 kg/m2 are defined as obese, this person is in the obese class.

**How is Obesity Classification Made in Body Mass Index Calculation?**

The comments to be made within the scope of the body mass index value in the obesity classification made by the World Health Organization are as follows:

- Those below 18.5 kg/m2 are called weak.
- Those between 18.5 kg/m2 and 24.9 kg/m2 are considered normal weight.
- When you have your body mass index calculated by wondering if you are overweight; If the result is between 25 kg/m2 and 29.9 kg/m2, you are considered overweight.
- Those who reach a result between 30 kg/m2 and 39.9 kg/m2 after the calculation are called obese.
- Results over 40 kg/m2 are called severely obese, that is, morbidly obese.
