What is indicated by a BMI of 30 or greater?

A Body Mass Index (BMI) of 30 or greater indicates obesity. BMI is a numerical value derived from an individual’s weight and height, and it is used as a screening measure to categorize people into different weight status categories.

The classification system for BMI typically defines the following ranges: underweight is a BMI less than 18.5; normal weight falls between 18.5 and 24.9; overweight is classified as a BMI between 25 and 29.9; and obesity begins at a BMI of 30 and continues onward into higher categories as the BMI increases.

When someone has a BMI of 30 or above, it signifies that their weight exceeds what is considered healthy for their height. This classification of obesity is significant because it is associated with an elevated risk of various health complications, including cardiovascular disease, type 2 diabetes, and certain types of cancer, making it an important factor in lifestyle medicine and healthcare interventions.
