Body mass index, also known as body mass index, is a number derived by dividing the number of kilograms of body weight by the square of the number of meters of height, which is a standard weight commonly used in clinical practice to measure the fatness of the human body and to determine whether it is healthy or not. The normal value of the human body mass index for adults is between 18.5-24, below 18.5 is too light, if more than 24, between 24-27 is overweight, in more than 27 is considered obese, if it is higher than 32 is very obese. If the body mass index is over the standard, it will greatly increase the occurrence of hypertension, hyperlipidemia, diabetes, and also has a direct relationship with the occurrence of cardiovascular disease.
