Girls especially don't want their figures to be out of shape, so they are very concerned about their weight. They always feel that their weight has not reached the standard weight, so they will blindly lose weight. In fact, it is very bad for the body. The weight standard should be determined according to your height. Everyone's standard is different. Don't let your weight become too low or too high. Those who exceed the standard weight by 10% to 20% have the lowest mortality rate. When the body weight is too low or too high by 30%, it is easy to cause diseases and shorten life span. The reason why fatter people live longer is that they have a thicker layer of subcutaneous fat, and are more resistant to cold and disease than ordinary people, and can better withstand the "torture" of disease. Thin people have relatively weak resistance and poor adaptability to the environment, especially to acute infectious diseases such as influenza, upper respiratory tract infection, pneumonia, etc., so they are prone to many diseases and have a short life. Medical research has also found that if women lose weight significantly after the age of 50, their likelihood of fractures, especially hip fractures, is greatly increased. In addition, the incidence of visceral prolapse is very high in thin people, the most obvious of which is gastroptosis. Therefore, when people reach old age, although they cannot be too fat, they cannot be too thin either. It is best to be a little fatter. Of course, regular exercise and mental health are also important. Body mass index = weight (kg) divided by height (m) squared (kg/m2) Normal weight: BMI = 18 - 25 Overweight: BMI = 25 - 30 Mild obesity: BMI > 30 Moderate obesity: BMI > 35 Severe obesity: BMI > 40 Standard weight for children and adolescents Standard weight = age x 2 + 8 (3 - 7 years old) Standard weight = age x 3 + 10 (7-16 years old) Mild obesity: 20% - 30% above standard weight Moderate obesity: 40% - 50% above standard weight Severe obesity: more than 50% above standard body weight Normal Overweight Mildly obese Moderately obese Severely obese 6- 11 years old 16-19 19-21 21-23 23-27 27- Other calculation methods ① Adult: (height (cm) - 100) × 0.9 = standard weight (kg) ②Male: Height (cm) - 105 = Standard weight (kg) Female: Height (cm) - 100 = Standard Weight (kg) The above two calculation methods have basically been widely adopted. In addition, the Academy of Military Sciences has also introduced a method to calculate the ideal weight of Chinese people: Ideal weight for northerners = (height cm-150) × 0.6 + 50 (kg) Ideal weight for southerners = (height cm-150) × 0.6 + 48 (kg) This calculation method seems to be more suitable for Chinese people in the north and south. The simple method to calculate the standard weight of children is: 1 to 6 months: birth weight (kg) + age in months × 0.6 = standard weight (kg) 7-12 months: birth weight (kg) + age in months × 0.5 = standard weight (kg) Over 1 year old: 8 + age × 2 = standard weight (kg) |
