Frequently Asked Questions

What is BMI and how is it calculated?

BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated as: BMI = weight (kg) / height² (m²). For imperial units: BMI = (weight in pounds × 703) / height² (inches²).

What is a healthy BMI range?

For adults, a healthy BMI is typically between 18.5 and 24.9. BMI below 18.5 is considered underweight, 25-29.9 is overweight, and 30 or above is obese. However, BMI doesn't account for muscle mass or body composition.

Is BMI accurate for everyone?

BMI is a useful screening tool but has limitations. It may not be accurate for athletes with high muscle mass, pregnant women, elderly people, or certain ethnic groups. Always consult a healthcare professional for personalized health advice.
