Calculate Your BMI

It's important to realize that BMI is not the most accurate determination of whether or not you are at an unhealthy weight. For example, if you are extremely muscular, your BMI may show as "Overweight" or even "Obese," when you're not. By the same token, if you are a "Normal" BMI, but have a very high body fat percentage, you may have the same health risks as someone with an "Obese" BMI.

BMI or "Body Mass Index" is based on the following formula:

(	Weight in pounds	)	* 703
	______________
	Height in inches2

BMI is only one tool in your health arsenal. Body fat percentage is a much better predictor of health risks than the ratio of your height to your weight.

This calculator uses what is called the "Harris-Benedict Formula" to determine your daily calorie needs. There are a few things that are important to remember about this formula. First, the formula was devised many years ago, and has in recent years been determined to have up to a 20% error rate, depending upon the percentage of body fat and other variables. (For this reason, the calculator shows plus and minus 5% and 20% so you can get an idea of the range.)

Secondly, the modification for your "lifestyle" (sedentary vs. moderately active and so forth) is really a bit of a guess. "Sedentary" is "little or no exercise" and you can imagine that there can be quite a bit of difference between "little" and "no" exercise.

Weight loss cannot, unfortunately, be boiled down into an exact number. All this can do is give you an idea of a potential range. Chances are good, however, that if you limit your intake to the lower end of the spectrum, you may be able to lose weight, but different people have different metabolisms and so you may need fewer or more calories.

Calculation of your "Basal Metabolic Rate" (or "Resting Metabolic Rate" as it's sometimes called) is only one tool in your fitness arsenal.
