1. What Is The Body Mass Index (IMC)?

The Body Mass Index (IMC) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple and widely used method to classify underweight, normal weight, overweight, and obesity.

2. How Does The Calculator Work?

The calculator uses the IMC equation:

Where:

• \( peso \) — Weight in kilograms (kg)
• \( altura \) — Height in meters (m)

Explanation: The equation calculates body mass index by dividing weight in kilograms by the square of height in meters.

3. Importance Of IMC Calculation

Details: IMC is an important screening tool to identify potential weight problems in adults. It helps assess health risks associated with underweight, overweight, and obesity, though it doesn't directly measure body fat.

4. Using The Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). For accurate results, measure weight and height using calibrated equipment.

5. Frequently Asked Questions (FAQ)

Q1: What are the IMC categories?
A: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25-29.9), Obesity (≥30).

Q2: Is IMC accurate for everyone?
A: IMC may not be accurate for athletes (high muscle mass), elderly (muscle loss), pregnant women, or children.

Q3: How often should I calculate my IMC?
A: For general monitoring, every 3-6 months is sufficient unless you're actively trying to change your weight.

Q4: What are the limitations of IMC?
A: IMC doesn't distinguish between muscle and fat, doesn't account for fat distribution, and may not be suitable for all ethnic groups.

Q5: Should IMC be the only measure of health?
A: No, IMC should be used with other measurements like waist circumference, body fat percentage, and overall health assessment.
