What is your BMI?

BMI (Body Mass Index) is a measure of an adult's weight in relation to their height. It is a very convenient way to determine whether or not your weight is in a healthy range.

To find your BMI, just take your weight in kilograms and divide it by your height in meters (squared). BMI can help you determine if you are underweight, normal weight, overwieight, obese or extremely obese.

Underweight = Less than or equal to 18.4
Normal weight = 18.5 - 24.9
Overweight = 25.0 - 29.9
Obese I = 30.0 - 34.9
Obese II = 35.0 - 39.9
Extreme obesity = Greater than or equal to 40

(Or you can just look at this chart)
Although BMI is a simple way to classify your weight, it is important to remember that BMI works well for the general population and not for individuals necessarily.
For example, look at this picture below:

These males are the same height and weight, so therefore, they have the same BMI and they are both classified as obese. But clearly, the male on the left is not "obese". He is in great physical shape and has a great amount of muscle mass. It is important to remember that muscle weighs more than fat.

So when figuring out your BMI, don't get too caught up in the numbers. BMI is just a good way for most people to classify their weight to determine if it is healthy or not. It is also good to keep in mind that if someone is classified as "underweight", they can be more at risk for disease/complications than someone who's weight is classified "normal".
