According to the BMI standard calculation, the height of 168cm, the standard weight is 52.21~67.46kg. Body Mass Index, or BMI for short, is an important standard for measuring the degree of fatness and thinness of the human body and whether it is healthy or not. To calculate the standard height and weight, we need to use the important index of body mass index, and the formula for calculating BMI is: BMI = weight (kg) ÷ height (㎡). For China’s population, the relevant standards of BMI: BMI <18.5kg/m2 on behalf of thin; BMI between 18.5 ~ 23.9kg/m2 for normal; BMI between 24 ~ 27.9kg/m2 that is at the level of overweight; BMI ≥ 28kg/m2 that is in the range of obesity. For a person with a height of 168cm, the standard BMI should be 18.5~23.9kg/m2. Therefore, the corresponding weight should be 52.21~67.46kg, lower than 52.21kg is thin, higher than 67.46kg is overweight. Overweight people can combine dietary adjustment and exercise to control their weight within the standard range in time to avoid certain health effects caused by obesity.
