What is the BMI threshold indicating obesity?

The BMI threshold indicating obesity is 30. This classification is based on the Body Mass Index (BMI) scale, which is a widely used tool for assessing an individual's body weight relative to their height. A BMI of 30 or greater is considered obese because it is associated with an increased risk of various health issues, including heart disease, diabetes, and certain cancers.

Understanding the BMI categories can help in identifying individuals who may benefit from interventions to improve their health. The categories are generally defined as follows: a BMI below 18.5 is underweight, a BMI between 18.5 and 24.9 is normal weight, a BMI between 25 and 29.9 indicates overweight, and a BMI of 30 or above signifies obesity. This classification plays a crucial role in public health as it guides health professionals in assessing health risks and making recommendations for lifestyle changes or medical interventions.
