The standard formula to calculate your body fat percentage is relatively complex based on the Department of Defense formula. Accordingly, the formula for males would be % body fat = 86.010 x log10 (abdomen – neck) – 70.041 x log10 (height) + 36.76. For instance, one observational study of more than 50,000 older adults in Canada measured both their BMI and body fat percentage. A low BMI and high body fat percentage were associated with increased mortality, per the April 2016 research in ‌Annals of Internal Medicine‌. This reveals the limitations of BMI — a person with a small frame There are multiple lean body mass equations (and they vary between sexes as well). We're using the Boer formula, which is said to be the most accurate. LBM (men) = 0.407 × weight [kg] + 0.267 × height [cm] - 19.2. LBM (women) = 0.252 × weight [kg] + 0.473 × height [cm] - 48.3. However, if you know your fat concentration, you can determine Or determine your BMI by finding your height and weight in this BMI Index Chart. If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese From the body fat chart above, you can see that this is a dangerously low percentage. A better goal might be for the woman to reduce her body fat from 23% to 18%. In this case: 130 pounds x 0.18 = 23 pounds body fat. 100 pounds lean body mass + 23 pounds body fat = 123 pounds goal weight. So, for this individual to achieve a lean, but healthy Why it works: Relative Fat Mass aims to give a more accurate measurement of body fat percentage than BMI, by using your height and waist circumference to measure your whole-body fat total. All you Obesity is defined as an excessively high amount of body fat or adipose tissue in relation to lean body mass. Being obese means that body fat is now beyond an accepted standard for your height. Currently, 34 percent of Americans are overweight and a separate 34 percent are obese, according to the Center for Disease Control and Prevention in Standard Methods for Determining Body Fat Using Body Circumferences, Height, and Weight, page . 23.
