They say it's not good to be too thin. How thin is too thin? What is the standard?
Hello: subtract 100 from the centimeters of height and multiply it by 0.9, and the answer is my standard weight. If the individual's height is 180cm, the standard weight is (180-100) × 0.9 = 72kg, which is normal if it is lower or higher than the standard weight 10%. If it is too much, it is too thin.
