1. What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. 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:

Where:

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

BMI Categories:

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5 to 24.9
• Overweight: BMI 25 to 29.9
• Obese: BMI 30 or greater

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening method for weight category—underweight, healthy weight, overweight, and obesity. While it doesn't measure body fat directly, research has shown that BMI is moderately correlated with more direct measures of body fat.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is BMI accurate for everyone?
A: BMI may not be accurate for athletes with high muscle mass, pregnant women, the elderly, or children. It's a screening tool, not a diagnostic one.

Q2: How often should I check my BMI?
A: For most adults, checking BMI once every 6-12 months is sufficient unless you're actively trying to change your weight.

Q3: What's the difference between BMI and body fat percentage?
A: BMI estimates body fat based on height and weight, while body fat percentage directly measures the proportion of fat in your body. BMI is easier to calculate but less precise.

Q4: Can BMI be used for children?
A: BMI is calculated differently for children and teens, taking into account age and sex. This calculator is designed for adults only.

Q5: What should I do if my BMI indicates I'm overweight or obese?
A: Consult with a healthcare provider who can assess your overall health and recommend appropriate lifestyle changes or treatments.
