The two most common methods used are skin-fold measurement and bioelectrical impedance analysis (BIA). The idea is to shoot for is a range rather than a magic number. How much body fat is OK? Body-fat Percentage Ranges Hispanic women had the highest percentage body fat (29.8%). Asian women had 27.8% body fat, while Caucasian women, lower than Asian women, had 26.9%. While Asian women had the lowest BMI, they did not have the lowest percentage body fat. However, percentage body fat did not show the same distribution pattern. Asian men (23.7 kg/m2) and women (21.5 kg/m2) had the lowest mean BMI among the study sample, while Hispanic men (25.9 kg/m2) and women (23.5 kg/m2) had the highest mean BMI. A BMI cutoff of ≥30 kg/m2 has good specificity but misses more than 50% of people with excess fat.Įstimates for body composition among the college-aged sample were strikingly different for gender and race. The accuracy of BMI in diagnosing obesity is limited, particularly for individuals in the intermediate BMI ranges, in men and in the elderly. Therefore, recent research has shown that body-fat percentage may be a better measure of your risk of weight-related diseases than BMI. However, BMI does not distinguish fat from muscle. The CDC provides the following ranges for BMI values (calculated as your weight in kilograms over your height squared in centimeters) for adults:Īs your BMI increases, so does your risk of developing weight-related diseases, such as heart disease, stroke, type 2 diabetes and some cancers. It is widely used in medical research as an indicator of someone’s health status and disease risk. The BMI has been considered the most accurate way to determine the effect of weight on your health.
