Quick FAQs
Is BMI always accurate?
Not always. BMI does not distinguish between muscle and fat. Athletes may have a high BMI due to muscle mass. Use BMI as a guideline and consider body-fat measurements for a fuller picture.
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered healthy.
When should I consult a doctor?
If your BMI is outside the healthy range or you have health concerns or symptoms, consult a healthcare professional for a full assessment.
