How is BMI calculation made and why is it important?

BMI calculation (Body Mass Index)  is a tool used to estimate a person's body fat based on their weight and height. It is widely used by health professionals to evaluate an individual's weight status and identify potential health risks. In this article, we will explain how BMI is calculated and why it is important.


How to calculate BMI: The formula

Calculating BMI is simple and quick. To calculate BMI, all you need to do is divide your weight in kilograms by your height in meters squared. Here is the formula to calculate your BMI:


BMI = weight (kg) / height (m)²


For example, if someone weighs 70 kg and is 1.75 m tall, their BMI would be:


BMI = 70 / (1.75 * 1.75) = 22.86


BMI categories

Calculating BMI allows individuals to be classified into different categories based on their BMI. These categories are as follows:

  • BMI less than 16.5: underweight
  • BMI between 16.5 and 18.5: thinness
  • BMI between 18.5 and 25: normal weight
  • BMI between 25 and 30: overweight
  • BMI between 30 and 35: moderate obesity
  • BMI between 35 and 40: severe obesity
  • BMI greater than 40: morbid obesity

It is important to note that BMI calculation does not take into account the distribution of muscle mass and body fat. Therefore, it is possible for some individuals, such as athletes, to have a high BMI due to their significant muscle mass without presenting excess body fat.


Why is BMI calculation important?

BMI calculation is a key indicator of a person's health. By understanding how to calculate BMI, you can evaluate whether you are overweight, underweight, or have a normal weight, which can help you make informed decisions about your diet and physical activity.


Identifying health risks

BMI calculation is important because it can identify potential health risks associated with inadequate weight, overweight, or obesity. High BMI is associated with an increased risk of cardiovascular diseases, type 2 diabetes, high blood pressure, certain types of cancer, and other health problems. Conversely, a BMI that is too low can also lead to health problems such as anemia, osteoporosis, and a weakened immune system.


Tracking weight changes

BMI calculation is also useful for tracking changes in weight over time. By regularly measuring your BMI, you can determine whether your efforts to lose, maintain, or gain weight are effective. This information can motivate you to stay on track or adjust your dietary habits and level of physical activity to achieve your weight goals.


Planning a weight loss program

If you are looking to lose weight, BMI calculation can help you determine a realistic and healthy weight goal. By knowing your current BMI and identifying the desired BMI range, you can estimate the number of kilograms to lose to reach an optimal weight.


Adapting nutrition and exercise recommendations

BMI calculation can also help health professionals personalize nutrition and exercise recommendations for each individual. For example, someone who is overweight may benefit from a more intense physical activity program and reduced calorie intake, while someone who is underweight may require a higher calorie intake and a muscle strengthening exercise program.
