常见问题
What is BMI?
BMI (Body Mass Index) is a simple ratio of your weight to your height squared. It's a rough screening indicator for whether someone is underweight, normal, overweight, or obese — but it doesn't measure body fat directly.
Is BMI accurate for everyone?
BMI is a general guideline, not a diagnosis. Athletes with high muscle mass may show as 'overweight' even though they're healthy. Always consult a healthcare professional for personal advice.
