To begin with, the main method of measuring human body fat is the body mass index (BMI) which is correlated to weight and height values ​​to obtain an average ( Renneboog, 2014, paragraph 6). The author further states that “these arbitrary designations do not take into account individual characteristics such as body shape or natural muscularity, nor do they apply to children or the elderly” (Renneboog, 2014, par.6). However, BMI is not always accurate and has some limitations in measuring body fat, sometimes classifying people as obese when in reality they are not. Since BMI is not 100% reliable, it is acceptable that “this is a factor that requires more attention in the use of the terms “overweight” and “obese”” (Eaton & Clydesdale, 2014, para. 10). According to Eaton & Clydesdale, 2014, “BMI has been used in numerous medical studies, but even the National Institutes of Health (NIH) in the United States realizes its limitations in directly measuring body fat or muscle.” Finally, “it is recognized that the most accurate way to measure body fat is to weigh a person underwater or in a chamber that displaces air” (Eaton & Clydesdale, 2014, para. 3). According to the same author, “there is another accurate test for measuring human body fat, called a dual-energy X-ray absorptiometry (DXA) test, which uses X-rays to measure body fat” (Eaton & Clydesdale, 2014, para .3).
