Which BMI range defines obesity class III?

Which BMI range defines obesity class III?

• A. 18.5-24.9 kg/m²
• B. 30.0-34.9 kg/m²
• C. 25.0-29.9 kg/m²
• D. ≥40 kg/m²

Answer: (D)

BMI is a simple way to classify weight status from height and weight. Obesity is divided into three classes based on how high the BMI is. Obesity class III is defined as a BMI of 40.0 kg/m² or higher, reflecting a very high health risk and often called morbid or severe obesity. The other ranges correspond to normal weight (roughly 18.5–24.9), overweight (25.0–29.9), and obesity class I (30.0–34.9) or obesity class II (35.0–39.9). So the range that defines obesity class III is ≥40 kg/m².
