Two simple weight formulas:
1 qualified weight (standard weight) (kg)= height (cm)- 105, normal weight (standard weight 10%), over 10%~20% is overweight, over 20% is obese.
2 Body Mass Index (BMI) = Weight (kg)/Height (m) 2
Weight cannot reflect body fat content, and the correlation between body mass index and body fat content is above 85%, which is suitable for most people, except athletes (muscular), pregnant women and lactating women (weight gain during childbirth). Body shape can be judged by body mass index:
For adults in China,
Body mass index < 18.5kg/m2 is emaciation;
18.5kg/m2≤ Body mass index < 23.9 kg/m2 is normal; 24kg/m2≤ Body Mass Index < 27.9kg/m2 exceeds the standard;
Body mass index > 28kg/m2 belongs to obesity.
The perfect proportion of a standard figure
1, up-and-down ratio: take the navel as the boundary, and the up-and-down ratio should be 5: 8, which conforms to the golden section law.
2, bust: measured from the armpit along the top of the chest, bust should be half the height.
3. Waist circumference: Under normal circumstances, measure the thinnest part of the waist. Waist is 20 cm smaller than bust.
4, hip circumference: in front of the body, the pubic bone is parallel to the largest part of the hip. The hip circumference is 4 cm larger than the chest circumference.
5, thigh circumference: at the top of the thigh, under the hip crease line. The thigh circumference is smaller than the waist circumference 10 cm.
6, calf circumference: calf fullness. The calf circumference is 20 cm smaller than the thigh circumference.
7. Foot neck circumference: at the thinnest part of the foot neck. The ankle circumference is smaller, and the leg circumference is smaller 10 cm.
8. Upper arm circumference: between shoulder joint and elbow joint. The upper arm circumference is equal to half the thigh circumference.
9. Neck circumference: The thinnest part in the middle of the neck. Neck circumference equals calf circumference.
10, shoulder width: the distance between two acromions. The shoulder width is equal to half the bust minus 4 cm.
