The standard weight of boys with 17 1 cm is 63.7 kg, and the standard weight plus or minus 10% is normal weight.
WHO calculation method:
Male: (height cm-80)×70%= standard weight; Female: (height cm-70)×60%= standard weight.
Standard weight plus or minus 10% is normal weight; Standard weight plus or minus 10%~20% overweight or underweight. More than 20% of the standard weight is obese or underweight.

Long-term underweight can lead to alopecia, anorexia, infertility, ulcers, dizziness, irregular menstruation and osteoporosis in the elderly. It will also have an impact on thinking and reasoning ability.
Weight is not necessarily fat, and thinness is not necessarily healthy; Some people are thin, but the visceral fat content is high; Being slightly fat can also be very healthy. You should be "fat" in weight and "thin" in body fat.
More muscles are healthy and overweight. Waist circumference and waist-hip ratio are important indexes to judge central obesity. The World Health Organization recommends that the waist-hip ratio of men exceeds 0.90 and that of women exceeds 0.85, which can be diagnosed as central obesity and requires timely weight management.
Experts suggest that to get the ideal figure, it is not as simple as gaining weight or losing weight, but increasing the muscle mass of the body. Especially for people over 60 years old, proper muscle building training and keeping "slightly fat" can not only protect cardiovascular and cerebrovascular diseases, prolong their life, but also avoid falling and improve their quality of life.
