1. What is BMI?

Body Mass Index (BMI) is a value derived from the mass and height of a person. It provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

With optional adjustments for individuals with high muscle mass:

• High muscle mass: 5% reduction
• Athlete level muscle mass: 10% reduction

3. Importance of BMI Calculation

Details: BMI is widely used as a screening tool to identify possible weight problems in adults. While it doesn't measure body fat directly, research has shown that BMI correlates to direct measures of body fat.

4. Muscle Mass Considerations

Details: BMI may overestimate body fat in athletes and others who have a muscular build. This calculator includes optional adjustments for individuals with higher than average muscle mass.
