Calculation formula:
The formula for calculating the standard weight of girls is (height -70)×60% (height in centimeters), from which it can be calculated that the standard weight of girls with birth height 168cm is about 58.8kg, and the normal weight range is that the fluctuation of the standard weight does not exceed 10%, and the normal weight of girls should be around 52.9-64.7kg. If your weight is within this range, you don't need to lose weight if you are not fat. But if you exceed a certain weight, it will affect the health of the human body, so a moderate diet is very important for the human body. Moderate exercise and weight control will not only make you healthy, but also make you happy. ?
Weight range:
Body mass index = weight (kg)/ height (m) 2, with 18.5-23.9 as the normal range, body mass index < 18.5 is called underweight, body mass index ≥24 is called overweight, and body mass index ≥28 is called obesity. Women's low weight may not only cause hair loss, memory loss, osteoporosis and other adverse effects, but also cause a series of symptoms such as low estrogen level, affecting fertility. So you should control your weight and keep healthy. Overweight 10%- 20% above standard weight, obesity 20% above standard weight; The standard weight below 10%-20% is thin, and the standard weight below 20% is thin. Because the values obtained by different weight algorithms may be slightly different, body mass index (BMI) is widely used as the standard to judge normal, overweight, obesity, emaciation and emaciation, especially when judging whether the weight is healthy according to the height.
Danger:
Women's low weight may not only cause hair loss, memory loss, osteoporosis and other adverse effects, but also cause a series of symptoms such as low estrogen level, affecting fertility. Overweight or obesity will increase the risk of hypertension, diabetes, atherosclerosis, fatty liver and other diseases, so the weight should be controlled within the normal range. It is suggested that people with low weight should actively supplement nutrition under the guidance of doctors. Overweight people should lose weight by controlling diet and strengthening exercise, and avoid dieting to lose weight. This will not only cause nutritional deficiency, but also rebound quickly, which will also cause metabolic disorders and affect physiological functions such as normal menstruation.
Body mass index:
Standard weight is an important index to reflect and measure a person's health. Being too thin or too fat is harmful to your health. Normal weight is a relationship corresponding to height. Clinically, in addition to judging the patient's obesity with standard weight, it is also evaluated with body mass index (body mass index). Body mass index (BMI) refers to the patient's weight (kg) divided by the square of his height (m). Normal people's body mass index ranges from 18.5-24kg/m2, and those below 18.5 are thin, those above 28 are obese. You can also judge whether the weight is standard by the abdominal circumference. It is normal for non-pregnant women to have an abdominal circumference less than 85cm.
Does the figure ratio involve leg-to-body ratio, head-to-body ratio, waist-to-hip ratio and shoulder-to-hip ratio? , height measurement index, height and leg circumference index, etc. The usual figure proportion is mainly the proportion of height and weight.
According to China's standards, women's height and weight ratio will be different at different ages.
