Solution and Explanation
The Body Mass Index (BMI), a common and straightforward metric, categorizes overweight and obesity across all age groups. It is computed by dividing an individual's weight in kilograms by the square of their height in meters, as shown by the formula: \[ \text{BMI} = \frac{\text{Weight (kg)}}{[\text{Height (m)}]^2} \] BMI classifications are as follows:
- Underweight: BMI below 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI from 25 to 29.9
- Obesity: BMI 30 and above
