In their study, scientists analyzed 700 men and women between 20 and 60 years of age in a fitness club. The equations to calculate the percentage of body fat – expressed as BF%cal – include measurements for height ( H), abdominal circumference ( A), and neck circumference (N), and are as follows (all in cm): BF%cal (men) = 10.1 – 0.239H + 0.8A – 0.5N BF%cal (women) = 19.2 – 0.239H + 0.8A – 0.5N In a study published in the British Journal of Nutrition, a group of scientists from Israel developed distinct formulas for rapid and cost-free measurement of body fat percentage. Measuring whole-body and regional distribution of fat and lean mass in a medical setting through dual-energy X-ray absorptiometry (DEXA) can be costly and technically challenging. Two common body composition measurements are BMI and skinfold estimates, neither of which are very accurate. Weighing yourself on a bathroom scale does not give you enough information about your overall body composition. Body fat percentage provides important information on health status and fitness level.īecause of this, it is important to calculate your percentage of body fat and stay within the healthy range. There are a number of factors that can influence body fat percentage, including age, gender, diet, activity level, and genes.Īccording to the American Council on Exercise, men who are between 20-40 years old with over 25 percent body fat are considered “obese”, whereas a “healthy” range is described as between 8 and 19 percent.įor women in this same age group, any level over 39 percent is “obese” and 21 to 33 percent is considered “healthy”. What is the best body fat percentage for you?
