Obesity is a state of excessive body fat accumulation and is difficult to measure. Body mass index (BMI)—defined as weight in kilograms divided by the square of height in meters—has been used traditionally for its simplicity and the availability of data. Although shortcomings of using BMI have been acknowledged, its correlation with body fat percentage and its sensitivity in diagnosing obesity based on the body fat percentage have been verified for Korean people (Chung et al. 2016).
