## How to Calculate Body Mass Index

Body mass index is a good way to judge whether you are at a healthy weight or not. Body mass index is a standard metric used to determine who is in a healthy and unhealthy weight group. Body mass index aka BMI compares your weight to your height, calculated by dividing your weight in kilograms by your height in meters squared.

For example, you want to find out if you are normal or obese, you can use BMI calculator. First, multiply your height in squared: 1.75 x 1.75 = 3.06. Next, divide the weight lift by the square of height: 80 / 3.06 = 26.1. Finally, compare your BMI number (26.1) with the weight categories listed below:

Under 18.5 = underweight
18.5 – 22.9 = normal body weight
23 – 29.9 = excess body weight (obesity tendency)
30 and above = obesity

That way, your BMI, aka your body mass index, indicates that you are overweight. To make it easier for you to calculate what your body mass index is, and whether you are classified as ideal, under, or overweight, we have provided a BMI Calculator that you can use.

However, the body mass index cannot be used as a measure of ideal body weight. BMI is an easy calculation method that can provide basic information on your overall weight problem. This figure can act as a warning sign of danger and protect a person from dying from chronic obesity-related diseases.

BMI also does not take into account the amount and distribution of body fat, which is important for measuring a person’s risk of various chronic diseases. The reason is, thin people may still have a distended stomach or diabetes. And in some cases, a tall stature, like a bodybuilder (who can look like he is overweight thanks to his muscle mass), is not necessarily a bad thing; many people who are over “normal” weight are declared healthy. In addition, a low BMI number may be the result of certain diseases or aging factors.
