Frequently Asked Questions
How accurate is BMI for determining health status?
BMI is a useful screening tool but doesn't measure body fat directly. It works well for general populations but may not accurately assess athletes with high muscle mass or older adults with lower muscle mass.
What BMI range is considered healthy?
A BMI between 18.5 and 24.9 is generally considered healthy for adults. However, optimal ranges can vary based on age, ethnicity, and individual health factors.
