Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is weight in kilograms divided by height in meters squared. It's the WHO-recommended standard for assessing healthy weight.
What's the difference between China and WHO BMI standards?
China's standard is stricter: normal is 18.5–23.9 (WHO: 18.5–24.9), overweight starts at 24 (WHO: 25). This is because Asian populations face higher chronic disease risk at lower BMI levels.
What are BMI's limitations?
BMI doesn't distinguish muscle from fat — athletes may be misclassified as overweight. It also doesn't consider body fat distribution. Combine with waist circumference and body fat percentage for better assessment.
