Body mass index (BMI) is an index closely related to body fat, which takes into account two factors: weight and height. Body mass index is simple and practical, which can reflect the overweight and obesity of the whole body. It is more accurate to measure the risk of heart disease, hypertension and other diseases due to overweight than to identify them simply by weight.
Body mass index refers to the index obtained by dividing the weight in kilograms by the square of the height in meters, that is, the body mass index. Body mass index (BMI) is a widely used international standard to measure obesity and health status, which is mainly used for statistical purposes.
Normal weight performance
Waist circumference is mainly to judge whether visceral obesity. Men's waistlines exceed 90cm and women's waistlines exceed 85cm, all of which belong to visceral obesity. Many hospitals have body composition analyzers to analyze the percentage of body fat components. The definition of obesity is that the amount of adipose tissue in the body exceeds the normal value. The results of component analysis show that women exceed 30% and men exceed 25%, which belongs to obesity.
Height minus 105 is the standard weight minus 105 is 70kg, but the actual weight is 65kg. The calculation method of normal range is 70 minus 65 equals 5, 5 divided by standard weight equals minus 7%, and the difference between weight and standard weight is divided by standard weight. If the value obtained is within plus or minus 10%, it belongs to the normal range. Plus or minus 20%, respectively, belong to obesity or emaciation.
