BMI (Body Mass Index)
Body mass index is a number used as an indicator of underweight, normal body weight, overweight and obesity, allowing a statistical comparison of body weight for people of varying height. The index is calculated by dividing the weight of that person by the square of its height. In general, a BMI below 18.5 is considered to be underweight, which may be a symptom of some eating disorder or other health problem, while a BMI of over 25 is considered overweight and above 30 a symptom of obesity.…
