1, body mass index, body mass index (BMI) = weight (kg)/ height (m? ), BMI 18.5-23.9 is normal. 24.0-27.9 is overweight, and ≥28.0 is obese. The body mass index can not accurately describe the distribution of fat in the body, and can not distinguish the content of fat and muscle. Muscular people are often easily misjudged.
2. Ideal weight, ideal weight (kg) = height (cm)- 105 or height (cm)- 105? 0.85, (female). Within this range, plus or minus 10% is normal, 10%- 19.9% is overweight, and over 20% is obese.
3, waist circumference, female waist circumference greater than or equal to 80 cm, is the starting point of central obesity.
4. Waist-hip ratio and hip circumference measure the circumference of the most prominent point of the pelvis around the hip. Female > 0.85 was diagnosed as central obesity.
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.
More than 20% of the standard weight is obese or underweight.
Overweight calculation formula
Overweight% = [(actual weight-ideal weight)/(ideal weight) ]× 100%
Different age algorithm
Standard weight method
Mild obesity: 20%-30% overweight.
Moderate obesity: 30%-50% overweight.
Severe obesity: more than 50% of standard weight.
