How to calculate body mass index? This is a simple formula with which you can determine the state of the body and its degree of obesity. To use this formula, you need to know only two parameters of your body - this is your current weight and height. Any person can determine BMI on their own, this will require a centimeter tape and floor scales. Once everything you need is available, you can start calculating. How to calculate body mass index correctly? For accuracy, it is best to use a conventional calculator.
Body mass index, formula:
BMI = body weight (kg) / height squared (m).
In order to understand how to calculate the body mass index yourself and without difficulty, just consider an example.
To determine your BMI, you only need to replace the body mass and height data with your parameters.
Suppose we need to determine the BMI of a person whose height is 171 cm (1.71 m) and weight is 84 kg. First of all, you need to determine the growth in
squared (1.71 * 1.71 = 2.9241 m).
Next, you need to divide the body weight by the obtained squared growth (84 / 2.92 = 28.76). The result will be BMI. In this case, we received 28.76.
How to calculate the body mass index, we learned, but you need to know what it means. To do this, you just need a table that shows the results of BMI and their interpretation.
BMI table
BMI (result) | Decryption of the received data |
<16.5 | Severe weight loss |
18.51 - 24.99 | Normal body weight |
25.01 - 30 | Being overweight or pre-obese |
30.01 - 35 | Obesity (1 degree) |
The table ends at 35 BMI for a reason. Further, there is no point in continuing it, because it is already clear that BMI simply does not fit into the normal range. This means that you must immediately correct it and lose weight.
How to calculate
body mass index to get reliable data? Often BMI quite accurately determines the state of your body in relation to overweight and underweight. But there are also cases in which it is not enough to rely on the result of BMI, since the formula does not contain data on physical development and constitution. If a person has a wide, heavy bone with developed muscle mass, then obtaining the correct BMI data is difficult. After all, it will turn out overweight, and this is wrong, because this result is based on muscle mass, and not on the fat layer. In this case, it is not necessary to perceive the obtained data as a signal to lose weight, since, possibly, there is no obesity as such.
What if the result indicates overweight? You need to lose weight, the sooner the better for your body. Indeed, because of it there is a mass of diseases of varying severity.
BMI is a simple formula that shows problems with excess weight or their absence. Do not neglect these data. If there are problems with overweight, they need to be solved, because, except for you, no one will solve them. First of all, it is necessary for you. Eat properly, exercise, and the problem of excess weight will never affect you.
