BMI is routinely used to qualify an individual’s adiposity, yet it is simply a measure of an individual’s mass (kg) divided by their height2 (m2). According to the WHO international classification, individuals with a BMI between 18.5 and 24.99 are considered healthy, whereas those with a BMI between 25 and 29.99 or of 30 and above are considered overweight or obese, respectively. Recently and due to the growing number of individuals with BMI values above 30, it has also become necessary to further subdivide the obese category into three classes; obese class I (BMI 30–34.99), obese class II (BMI 35–39.99) and obese class III (BMI ≥ 40) [16].
