Frequently Asked Questions

What does BMI stand for?

BMI stands for Body Mass Index. It is a measure of body fat based on height and weight that applies to adult men and women.

Is BMI accurate?

BMI is a useful screening tool but has limitations. It does not directly measure body fat, so athletic individuals with high muscle mass may have a higher BMI despite being healthy. Consult a healthcare provider for a comprehensive assessment.

What BMI range is healthy?

A BMI between 18.5 and 24.9 is generally considered a healthy weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or higher is obese. However, individual health depends on many factors beyond BMI.

Can BMI change?

Yes, BMI changes as your weight or height changes. Regular exercise, balanced nutrition, and healthy lifestyle habits can help maintain or improve your BMI over time.
