Domestic scholars put forward a formula for calculating the standard weight by sex: average weight of male (kg) = height (cm)-105; Japanese scholars put forward a formula for calculating the standard weight of Asians according to their height: 1. If the height is below 159 cm, the standard weight (kg) = height-105; 2. Height 160cm: standard weight (kg) = (height-100) × 0.9. It should be noted that the standard weight calculated according to the above formula is not an absolute "standard", and the actual weight is higher or lower than the standard weight 10%, which should be regarded as normal weight.
I think it doesn't matter if the standard is not as long as you are healthy!
