What BMI classification indicates obesity?

The classification that indicates obesity is defined as a Body Mass Index (BMI) greater than 30. This threshold is established by health organizations, including the World Health Organization (WHO), and is widely accepted in clinical practices. Obesity at this level signifies a greater risk for various health issues, such as cardiovascular disease, type 2 diabetes, certain cancers, and other metabolic disorders.

BMI is calculated using a person's weight in kilograms divided by their height in meters squared. When the BMI exceeds 30, it indicates that the individual has a higher fat mass relative to their body composition, classifying them as obese. This classification helps healthcare professionals assess an individual's health risks and can guide treatment and lifestyle recommendations.

While categories above 30, such as BMI greater than 35 or greater than 40, do represent more severe forms of obesity (Class 2 and Class 3, respectively), the initial classification of any obesity starts at the >30 mark. Therefore, recognizing a BMI greater than 30 as the threshold for obesity is crucial for appropriate clinical intervention and public health strategies.
