Body Mass Index
BMI for adults is calculated by dividing weight by height squared.
BMI = 18.5-24.9 → normal weight
BMI> 25-29.9 → overweight
BMI> 30 → Obese
BMI does not take into consideration muscle and bone mass, age and sex of the individual, and may lead to erroneous results in two possible cases. When the person works out or when his muscle mass is large with higher BMI without having more fat. Another case is when a person because of age or a medical condition, has lost muscle mass and has a lower BMI without having less fat.
