When it comes to the body, there are several parameters that are used to determine one's physical status. Body weight is one of the most common, then there is body fat, lean body mass and something called Body Mass Index (BMI). The BMI is most often used as a quick reference in the medical and fitness industry to assess someone's body fat based on a relationship between his weight and height. When it comes to calculating it for men, there are various steps that need to be taken.
Step 1
Weigh yourself to get the most accurate reading of your weight possible. To do this, weigh yourself first thing in the morning on an empty stomach and after using the bathroom.
Step 2
Find out your height. Stand with your back up against a wall or inside a doorway. Look forward and place a small mark on the wall at the top of your head with a pencil. Use a tape measure to calculate your height. Once you get your height in inches, square it.
Step 3
Input the information into an equation. Divide your weight by your height, and then multiply the result by 703 to get your body mass index. Here's an example of a man who is 6-foot-3 and weighs 180 lbs.: 703 x (180/75x75) = 22.5.
Step 4
Compare your results. There is a range of BMI that you can check to evaluate where you stand. If you are less than 18.5, you are underweight. If you are 18.5 to 24.9, then you are normal; 25 to 29.9 is overweight and 30 or above is considered obese.
Tips and Warnings
- When you weigh yourself, either do it naked or just be in your underwear. Use an online calculator. There are various websites that have trackers available. One of them is set up by the Centers for Disease Control. All you do is punch in your height and weight, and your BMI automatically comes up.
