What is the definition of obesity?

Obesity is defined as a condition characterized by an excessive amount of body fat that poses health risks. The commonly accepted clinical definition states that a person is considered obese when their body weight is more than 30% above the ideal body weight. This definition is significant because it establishes a clear threshold for identifying individuals at higher risk for health issues related to obesity, such as cardiovascular disease, diabetes, and certain cancers.

The definition is supported by the Body Mass Index (BMI) metric, where a BMI of 30 or greater classifies an individual as obese. This classification aids healthcare professionals in assessing and managing patient health, as the prevalence of obesity is associated with various comorbidities. Therefore, identifying obesity as more than 30% over ideal body weight helps streamline the approach to treatment and can enhance patient outcomes through timely interventions.
