Obesity class II is defined by a Body Mass Index (BMI) value that ranges from 35 to 39.9. This classification is part of the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) standards, which categorize obesity into different classes based on BMI to help assess the risks associated with excessive body weight. Obesity class II indicates a level of obesity that significantly increases the risk of various health problems, including diabetes, cardiovascular diseases, and certain types of cancer.

The other BMI ranges provided do not fall under the classification of obesity class II. For instance, values from 30 to 34.9 correspond to obesity class I, while a range below 30, such as 25.0 to 29.9, is classified as overweight. A BMI of 40.0 and above defines obesity class III, which is often considered severe or morbid obesity. Understanding these classifications is crucial for health professionals in providing appropriate interventions and risk assessments related to body weight and its associated health effects.
