BMI Advanced Calculator

Role:
The BMI (Body Mass Index) calculator estimates whether a person has a healthy weight based on their height and weight, categorizing them as underweight, normal, overweight, or obese.

Key Questions & Answers

1. Is BMI accurate for everyone?
   No—it doesn’t account for muscle mass, bone density, or fat distribution (e.g., athletes may show as “overweight”).
2. What’s a healthy BMI range?
   • Underweight: <18.5
   • Normal: 18.5–24.9
   • Overweight: 25–29.9
   • Obese: ≥30
3. Why use BMI?
   Quick, simple screening tool for weight-related health risks (e.g., diabetes, heart disease).
4. Limitations?
   Doesn’t differentiate fat vs. muscle; less accurate for kids, pregnant women, or elderly.
