Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is a simple measure calculated from height and weight. It's used as a screening tool to categorize weight status.
What's a healthy BMI?
According to the WHO standard, a BMI between 18.5 and 24.9 is considered healthy. The Asian standard uses 18.5-23 as the healthy range due to different body composition characteristics.
Is BMI accurate for everyone?
BMI is a general screening tool and doesn't account for muscle mass, bone density, or distribution of fat. Athletes may have a high BMI due to muscle mass but be very healthy.
