Male: (height cm-80) × 70% = standard weight.
Female: (height cm-70) × 60% = standard weight.
Standard weight plus or minus 10% is normal weight.
Standard weight plus or minus 10 ~ 20% overweight or underweight.
Obesity or underweight is defined as plus or minus 20% of standard weight.
2, overweight calculation formula
Overweight% = [(actual weight-ideal weight)/(ideal weight) ]× 100%
Different age algorithm
Standard weight method
Standard weight (kg) = age x 8+8 (7- 16 years old)
Mild obesity: 20%-30% overweight.
Moderate obesity: 30%-50% overweight.
Severe obesity: more than 50% of standard weight.
3. Body mass index = square kilogram of body weight/square meter (kilogram)/height (meter)
Formula writing: body mass index = weight/(height) 2
Normal weight: body mass index = 18.5-25 (China physical health standard: normal range: 18.5~23.9, overweight 24.0~27.9, obesity ≥28.0).
Overweight: body mass index = 25-30.
Mild obesity: body mass index >; 30
Moderate obesity: body mass index >; 35
Severe obesity: body mass index >; 40
4. Standard weight = height (m) × height (m) × standard coefficient (female 20, male 22)
Standard weight plus or minus 10% is normal weight.
Standard weight plus or minus 10 ~ 20% overweight or underweight.
Obesity or underweight is defined as plus or minus 20% of standard weight.
5. Standard weight (kg) = height (cm)-105
For example, a man with a height of 170cm should weigh170 (cm)-105 = 65 (kg). Those who exceed the standard weight 10% are overweight, and those who exceed 20% are obese; Under 0/0% of standard weight/kloc, those below 20% are thin.
Note: The above calculation method is only applicable to adults. Not suitable for children, old people or people who are too short.
6, Blocker formula:
Height 165cm or less: standard weight (kg)= height (cm)- 100.
Height1over 65cm: standard weight (kg)= height (cm)- 1 10.
