BMI (Body Mass Index) and body fat percentage are popular measures to help determine your level of health and fitness. When used properly, they provide a more complete picture of your health than simply monitoring your weight. If you want to gain muscle or lose weight, understanding your BMI and body fat percentage will help you set appropriate health goals and track your progress.
Why measure BMI?
BMI is commonly used by doctors, wellness facilities, and within the insurance industry. It is based on a height to weight ratio, and is an indicator of your body size. It’s a general score that was designed to determine if you are within a “healthy range” for BMI. It’s also a way to assess risk for disease, as people with very high and very low BMIs are most likely to develop health problems.
However, the downside of BMI is that it doesn’t take into account body composition. An athlete with high muscle mass and low body fat may register as “obese” due to a high weight reading relative to their height. For example, a male wrestler in top physical condition might be 6’2”, weigh 220 pounds and have a BMI of 28. 28 is bordering on obese, which clearly isn’t correct.
How to determine BMI
You can calculate your BMI by using the following formula: [weight (lb) / height (in) / height (in)] x 703
Why measure Body Fat Percentage?
Your body fat percentage represents the proportion of fat on your body, as opposed to muscle, bone, and other lean tissue mass. For some avid exercisers and dieters, measuring body fat can be a more accurate measure of health than the weight on a standard bathroom scale. For example, as you begin an exercise regime, your body fat may be decreasing and your muscle mass increasing. If these happen simultaneously, you may not see a change on the scale – or you may even gain a few pounds! This can be very demotivating.
The advantage of using body fat percentages is that it provides you with a breakdown of your body composition, tailored to your individual body type. Healthy body fat ranges differ for men and women.
How to calculate body fat percentages
Body fat can be measured in a variety of ways. Skin fold calipers, hydrostatic weighing, body pods, and Bioelectrical Impedance Analysis (BIA), found in certain bathroom scales, are methods to measure body fat.
