1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight to assess body fatness. It provides a reliable indicator of body fat for most people and is used to screen for weight categories that may lead to health problems.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The formula divides a person's weight by the square of their height to calculate their BMI score.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool for weight categories that may lead to health problems. It helps identify potential weight problems for adults but is not a diagnostic tool.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accurate results, measure weight without heavy clothing and height without shoes.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For adults, 18.5-24.9 is considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: Is BMI accurate for everyone?
A: BMI may overestimate body fat in athletes and underestimate it in older people who have lost muscle mass.

Q3: How often should I check my BMI?
A: Periodic checks (every 6-12 months) can help track changes, but don't rely on it as your only health indicator.

Q4: Why is BMI different for men and women?
A: Men typically have more muscle mass than women at the same BMI, but the same BMI categories apply to both.

Q5: Should athletes worry about high BMI?
A: Athletes with high muscle mass may have high BMI without excess body fat. Additional measurements may be needed.
