What is Body Mass Index (BMI)
BMI (short for Body Mass Index) has received a lot of attention in recent years, as schools in the United States measure students on BMI and send BMI registration cards home. Schools in the US check the weight and size of students at school, calculate the BMI, send the information as a “bMI registration card” to parents at home or send it home.
Unfortunately, the Body Mass Index does not take into account that weight comes from fat and not muscle mass, so it uses weight as a formula. If you use a BMI calculator like the one on this page, you can enter your weight and height information and get the results.
Am I Overweight
You can have a higher BMI if you have more muscle mass, but that doesn’t mean you’re overweight. You may also have the same body mass – trained people with a normal BMI, and you may have less body fat than people who have exercised well. Children with small frames may have a “normal” BMI, but they can still have either too many body fats or a high BMI.
Athletes and people with muscular stature may have a BMI that classifies them as overweight or even obese, even though they are clearly fit.
What to do before calculating Body Mass Index (BMI)
Before calculating your BMI, it is important that you measure weight and height in kilograms and centimetres. This is because the weight-to-height ratio is square, and if you feel that your BMI does not accurately reflect whether you are overweight or obese, measuring the difference between your body mass index (BMI) and your height (height / weight ratio) will give you a more realistic estimate.
It is important to remember that measuring BMI does not make a difference whether you are male or female, have a larger or smaller build or have a higher muscle mass, but whether or not you have distributed fat throughout all areas of the body. In other words, BMI is useful for determining whether a person is obese or not, and is used to determine whether they are overweight or obese. BMI is not a perfect system for measuring body fat, but in most cases it is reliable and gives a fair indication of body fat levels.
