Frequently Asked Questions
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is generally considered a normal, healthy weight range for most adults.
Is BMI accurate for everyone?
BMI is a useful general screening tool, but it does not distinguish between muscle and fat, so it may be less accurate for athletes, older adults, or people with unusual body compositions. Consult a healthcare provider for a personalized assessment.
