What does BMI stand for?

BMI stands for Body Mass Index, which is a numerical value derived from a person's weight and height. It is commonly used as a screening tool to categorize individuals into different weight categories, such as underweight, healthy weight, overweight, and obesity. The calculation involves dividing an individual’s weight in kilograms by the square of their height in meters.

This measurement is significant because it helps assess body weight in relation to height, giving a more comprehensive view of body composition compared to weight alone. It is an important tool used by healthcare professionals to identify potential health risks related to weight and to guide individuals towards healthy lifestyle changes. Understanding BMI can also help raise awareness about proper nutrition and physical activity.

Other options confuse the terminology related to body composition and measurement, which is why they do not correctly define BMI. Body Mass Index is the established and widely accepted term used in health assessments.
