Obesity is classified based on Body Mass Index (BMI), which is a calculated value derived from a person's weight and height. The BMI categories for adults, as defined by the World Health Organization (WHO), are as follows:
1. **Underweight**: BMI less than 18.5
2. **Normal weight**: BMI 18.5 - 24.9
3. **Overweight**: BMI 25 - 29.9
4. **Obesity**:
- **Class 1 (Moderate obesity)**: BMI 30 - 34.9
- **Class 2 (Severe obesity)**: BMI 35 - 39.9
- **Class 3 (Very severe or morbid obesity)**: BMI 40 or greater
These categories provide a framework for assessing weight status and potential health risks associated with obesity. Note that BMI is a screening tool and does not directly measure body fat or account for other factors such as muscle mass, fat distribution, and overall health.
