1. What is Body Mass Index (BMI)?

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults. It is defined as a person's weight in kilograms divided by the square of their height in meters.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

Where:

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

Explanation: BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.

3. Importance of BMI Calculation

Details: BMI is an inexpensive and easy screening method for weight category—underweight, healthy weight, overweight, and obesity. It helps identify potential weight problems that may lead to health issues.

4. Using the Calculator

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above indicates obesity.

Q2: Are there limitations to BMI?
A: Yes, BMI doesn't account for muscle mass, bone density, overall body composition, and racial and sex differences. Athletes may have a high BMI due to increased muscle mass rather than fat.

Q3: Is BMI applicable to everyone?
A: BMI may not be accurate for children, pregnant women, the elderly, and highly muscular individuals. Different BMI categories apply for Asian populations.

Q4: How often should I check my BMI?
A: For most adults, checking BMI every 6-12 months is sufficient unless you're actively trying to lose or gain weight.

Q5: Should BMI be the only measure of health?
A: No, BMI should be used as a screening tool alongside other measurements like waist circumference, body fat percentage, and overall health assessment.
