Generally speaking, according to the WHO standards, 59.85kg~73.15kg for 175cm men and 57.7~69.3kg for 175cm women are more appropriate. Human body weight is related to height, according to the calculation method stipulated by WHO, the standard weight for men is (height cm-80) × 70%, and the standard weight for women = (height cm-70) × 60%. According to this formula, if the height is 175cm, then the ideal weight for men is 66.5kg and for women is 63kg. However, since different people have different physical qualities, in order to know whether the specific weight is appropriate, it is necessary to judge according to the specific ratio between the actual weight and the standard weight. If the ratio is within ±10%, then it means that the body is in good nutritional condition and is more appropriate. It can be seen that it is more appropriate for a 175cm male to weigh approximately 59.85kg~73.15kg, while it is more appropriate for a 175cm female to weigh 57.7~69.3kg. If the actual ratio is more than 10~20%, then it is overweight, and if the ratio is less than 10~20%, then it is thin and the body may have malnutrition. In order to maintain a proper weight, it is important to develop good eating habits, pay attention to nutrition, go to bed early, get up early, ensure adequate sleep, and take appropriate outdoor exercise.
