A height of 1.80 meters normally weighs around 60~80kg for men and 59.4~72.6kg for women. According to the height and weight calculation method set by the World Health Organization, the standard weight for a 1.80m male is (height cm-80) x 70% = 70kg, and the standard weight for a 1.80m female is (height cm-70) x 60% = 66kg, while ±10% of the range of the standard weight is the normal weight. Therefore, it is normal for a 1.80m male to weigh 60-80kg and for a 1.80m female to weigh 59.4-72.6kg. If it exceeds 10% to 20% of the standard weight, it is called overweight, and if it exceeds 20%, it is called obesity, while emaciation means that the patient’s actual weight is less than 20% of the standard weight. Within this standard is generally a reasonable weight, more than this standard, can be adjusted under the guidance of a professional physician, it is recommended to cultivate healthy habits, maintain a balanced diet, eat more fruits and vegetables and food rich in dietary fiber to maintain good health.
