What is the BMI range that indicates obesity?

The BMI range that indicates obesity is defined as a Body Mass Index of 30 or higher. This classification helps assess whether an individual has a healthy body weight in relation to their height, with the boundaries set to categorize different weight statuses. A BMI of 30 and above not only reflects excessive weight but also correlates with increased risks of various health conditions, including heart disease, diabetes, and certain cancers.

In contrast, the other ranges provided indicate different weight categories. A range of 25-29.9 is classified as overweight, which signals a higher risk of health problems but does not meet the threshold for obesity. A BMI between 18-24.9 falls within the normal weight range, indicating a healthy weight status, while a BMI under 18 signifies underweight status, which may also carry its own health risks. Thus, the clear distinction of 30 and above as the obesity threshold is crucial for medical assessments and public health guidelines.
