Standard weight calculation formula: height (cm)- 105= standard weight (kg). For example, for girls of 158, it is enough to control their weight at around 53kg; If she weighs less than 48kg, she is thin; If you weigh more than 63kg, you are overweight.

According to the height and weight of girls, we can also calculate the body mass index. The formula for calculating the body mass index is: body mass index = weight/height square (international unit kg/m 2).

So if a girl with a height of 158 weighs 53kg, then her body mass index is 53/ 1.58? = 19.55. If this value is between 16.5 and 2 1.9, it means a standard weight and a standard figure.

In fact, both overweight and underweight are harmful to health. Being overweight can induce some metabolic diseases, such as hypertension, diabetes, hyperlipidemia and hypercholesterolemia, and some people even have mental illness.

If the weight is too low, it will also endanger your health. First of all, it will lead to malnutrition, hypoglycemia, anemia, decreased energy and other problems. Some people skip meals in order to lose weight and even suffer from anorexia.
