The optimal weight for a height of 168cm is not a definite value, but can fluctuate within the range of 10% increase or decrease of the standard weight. If 168cm is the height of an adult, the optimal weight range should be 56.7kg to 69.3kg.
A common method of calculating the standard weight of an adult is: standard weight (kg) = height (cm) – 105. Subject to the influence of body shape and personal aesthetics and other factors, the optimal weight can fluctuate up and down 10% of the standard weight. Therefore, for an adult with a height of 168cm and a standard weight of 63kg, the optimal weight range is 56.7kg to 69.3kg.
If an individual’s weight exceeds 10% of the standard weight, he/she is called overweight; if an individual’s weight exceeds 20%-50% of the standard weight, he/she is called obese; if an individual’s weight is less than 10% of the standard weight, he/she is called thin.
If an individual’s weight is too much below or above the normal value, he or she should go to the hospital in time for examination to clarify the cause of the abnormal weight and carry out targeted treatment as soon as possible.
