Calculating your BODY FAT %
When you think about losing weight, more importantly than weight is the amount of fat you are carrying around. This fat is measured with what is called Body Mass Index, or BMI. For women, if you are fit, your percent of body fat should range from 21% to 31%. If you are in incredible shape, that could be as low as 10%. For men, fit should be between 14% and 25%, and excellent shape, as low as 2%.
To calculate your body fat, write down how much you weigh (be honest – no one will see this but you). Multiply your weight by 703. Next, write down your height, in inches. Multiply by that same number. Then you will divide your weight number by your height number. That is your BMI. For example, if your weight were 150 pounds x 703, your weight answer would be 105,450. If your height is 5’4”, that would be 64 inches x 64 for a total of 4,096. Taking the 105,450 divided by 4,096, you come out with a BMI of 25.7.
