The World Health Organization's (WHO) recommended healthy BMI range is 18.5 - 25 for both males and females. Based on the BMI range, it is possible to find out a healthy weight for any height. BMI is a commonly used metric for determining IBW. It is widely used in the medical field as a quick indicator of potential health complications. The higher the BMI, the higher the chance a person will suffer from health problems such as obesity, diabetes, heart disease, and many more. It is an indicator used by doctors to advise their patients of potential health problems, especially if there is a noticeable progressive increase in their BMI, and is currently the official metric for classifying individuals according to different obesity levels.
