## Weight Loss Tip: How to Calculate Body Mass Index (BMI)

TweetIf you want to lose weight you must know how to correctly calculate your BMI or body mass index. BMI is measured by comparing your weight and height. It divides your weight by your height squared and where that number is on a chart lets you know if you are underweight, at a healthy weight or overweight. BMI doesn't measure body fat so the calculations can sometimes in inaccurate. Athletes or anybody with a lot of muscle will often times get a number that is not accurate. Muscle weighs more that fat and BMI doesn't take this in account. Only an average person will get accurate results with average muscle and body fat.

The correct formula for calculated BMI is kg/m2. This is your weight in kilograms divided by your height in meters, squared. For instance, if a person is 2.0 meters tall, you would square that number (times it by itself) which is 2.0 times 2.0 which equals 4. Then you divide that person's weight, if the person weighed 80 kilograms you would divide 80 by 4 which equals 20. A healthy weight range is anywhere between 18.5 and 24.9 . If your BMI is between 25 and 29.9 you are at a healthy weight but anything above 30 is obese.

If you want to calculate in pounds and feet instead of kilograms and meters then you just change the suit. You would multiply the weight of 176 pounds by 4.88 which equals 858. Then divide the height of 6.5 feet squared which is 42.64. The equation would be 858 divided by 42.64 with a sum of 20.1 which is not too much higher than the metric result.
