Answer 1

The Body Mass Index (BMI) is the simple and widely used method to classify overweight and obesity for all ages. It is calculated by dividing a person’s weight in kilograms by the square of their height in meters: \[ \text{BMI} = \frac{\text{Weight (kg)}}{[\text{Height (m)}]^2} \] Classification based on BMI:

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5 – 24.9
• Overweight: BMI 25 – 29.9
• Obesity: BMI 30 or more
