adults aged 20–74 are obese (including 9% who are severely obese) and an additional 31% are overweight. Results from the 2017–2018 NHANES survey indicate that an estimated 43% of noninstitutionalized U.S. ĭata from the 2003–2006 NHANES survey showed that fewer than 10% of American adults had a "normal" body fat percentage (defined as 5–20% for men and 8–30% for women). But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. QuickStats: Mean Percentage Body Fat, by Age Group and Sex – National Health and Nutrition Examination Survey, United States, 1999–2004 As such, BMI is a useful indicator of overall fitness for a large group of people, but a poor tool for determining the health of an individual. While BMI largely increases as adiposity increases, due to differences in body composition, other indicators of body fat give more accurate results for example, individuals with greater muscle mass or larger bones will have higher BMIs. The widely used body mass index (BMI) provides a measure that allows the comparison of the adiposity of individuals of different heights and weights. The body fat percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or weight. A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis.
Storage body fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Essential body fat is necessary to maintain life and reproductive functions. (2013).The body fat percentage ( BFP) of a human or other living being is the total mass of fat divided by total body mass, multiplied by 100 body fat includes essential body fat and storage body fat.

It is important to note that skinfold measurements vary widely, and body fat distribution can differ, based on race, age, sex, and physical activity. People can then enter these measurements into an online calculator, which estimates body fat percentage. It is important for people to take the measurements at the same sites each time.
Females should measure skinfolds on the triceps, thigh, and just above the hip bone. Males should measure skinfolds on the chest, thigh, and abdomen. Due to differences in body fat distribution, males and females need to take measurements in different areas. It requires a person to use calipers to measure the thickness of skinfolds. Measuring the thickness of skinfolds in different areas of the body can help a person estimate their body fat percentage.Īccording to the American Council on Exercise, this method provides fairly accurate results. The body stores a large amount of fat directly beneath the skin. Share on Pinterest A person can estimate their body fat percentage by measuring the thickness of skinfolds in different areas of the body.
