If calculated according to the calculation method of female standard weight: (161.5 (cm)-100) x 0.9 (kg)-2.5 (kg) = 52.85 (kg).

The normal range is: standard weight plus 10% or minus 10%, that is, the normal weight is between 47.565kg and 58. 135kg, so the weight of 48.5kg belongs to normal weight and is not too thin. This algorithm is more suitable for orientals.
