Optimum value of body mass index for height and weight

Body Mass Index (BMI), that is, body mass index (BMI), is an index closely related to body fat, which mainly reflects overweight and obesity. Because the body mass index calculates the proportion of body fat, it is more accurate to measure the risk of heart disease, hypertension and other diseases because of overweight than to identify them simply by weight. The world standard of obesity is that the body mass index is in the normal range of 18.5 to 24.9, the body mass index greater than 25 is overweight, and the body mass index greater than 30 is obese. Asian obesity standard: Asians are too young to be measured by the world obesity standard. For example, when the Japanese body mass index is 24.9, the risk of hypertension will increase by three times; In China, the mortality rate of body mass index is the lowest, which is 23.7. The higher the mortality rate, the greater the initial increase. Experts believe that the obesity standard of Asians should be that the body mass index is normal at 18.5-22.9, that the body mass index is greater than 23 for overweight, and that the body mass index is greater than 30 for obesity. China obesity standard: China experts believe that although China people belong to Asian race, the upper limit of the normal range of body mass index should be lower than the Asian standard. Some experts suggest that the best value of China people's body mass index should be 20-22, with a body mass index greater than 22.6 as overweight and a body mass index greater than 30 as obesity. Measurement standard of body mass index in China:

Body mass index-slightly thinner in <20.

20< Body Mass Index <24 is normal.

24< body mass index <26 is slightly fat.

26< Body Mass Index <30 is overweight

30< Body Mass Index <40 Obesity

Body mass index-GT40 is severely obese. Simple conversion of ideal weight: (the ideal weight calculated by this station may be different from other stations, and this station adopts a calculation method more suitable for orientals)

Male: Ideal weight (kg) = (height (cm)-80) * 0.7.

Female: Ideal weight (kg) = (height (cm)-70) * 0.6 Body mass index Calculation formula: Body mass index = weight (kg)/ (height (m)× height (m).

Calculation method of beauty weight: the slim figure pursued by beauty-loving women is the so-called beauty weight. It is calculated by subtracting 5 kilograms from their ideal healthy weight. This is a requirement for a better figure, and it is also the latest interpretation of the golden figure now.

The perfect figure should be that the leg length below the waist accounts for 6 1.8% of the whole body, which is commonly known as the golden section. Chest circumference = height (cm) ×0.535, waist circumference = height (cm) ×0.365 and hip circumference = height (cm) ×0.565. The error between the actual calculation index and the standard index is 3 cm, which is the standard. Less than 5 cm means too slim (thin), and more than 5 cm means too plump (fat). But the measurement standard of professional female model is different. Due to professional needs, their measurement standards have a certain gap with the normal standards. Another method: a scientific and convenient formula can help you know whether the size of the chest is just right for your figure. First measure the chest circumference (unit: cm), then measure the clear height, and then start the calculation. Bust/height =? The result is the size coefficient of your own chest.

Small chest: the coefficient is less than 0.49.

Standard index: 0.5 to 0.53

Aesthetic standard: 0.54 to 0.6

Chest circumference is too large: the coefficient is greater than 0.6.
