Clinically, the standard weight is calculated by subtracting 105cm from the height to get the number. If the height is 158cm, the standard weight should be 53kg, and if the actual weight is more than 10% of the standard weight, it is clinically called overweight. If the actual weight is more than 20% of the standard weight, it is clinically called obese. If the actual weight is less than 10% of the standard weight, it is called thin. If the actual weight is less than 20% of the standard weight, it is clinically called wasting.
