Frequently Asked Questions
How is BMI calculated?▼
BMI is calculated by dividing your weight in kilograms by your height in meters squared: BMI = weight(kg) / height(m)². For example, a person weighing 70kg and 175cm tall has a BMI of 70 / (1.75)² = 22.9.
Why is the BMI standard different for Asians?▼
Research shows that Asian populations have higher body fat percentages and greater health risks at lower BMI values compared to Western populations. The WHO Western Pacific Region recommends overweight at BMI 23+ and obese at 25+ for Asians, versus 25+ and 30+ for Western standards.
Is BMI a reliable health indicator?▼
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass, so muscular individuals may be classified as overweight. It also doesn't account for fat distribution — abdominal fat carries more health risk. For a complete assessment, consider waist circumference and body fat percentage alongside BMI.
