What does BMI stand for?

BMI stands for Body Mass Index, which is a standardized measurement used to assess the body weight relative to height. It is calculated by taking a person's weight in kilograms and dividing it by the square of their height in meters. This index helps to categorize individuals into various weight categories, such as underweight, normal weight, overweight, and obesity. By doing so, it can provide insights into potential health risks associated with being above or below a healthy weight range. Understanding and utilizing BMI can play a critical role in health assessments and may guide individuals towards making informed lifestyle changes for better health outcomes.

In this context, the other options do not accurately reflect the widely recognized and used term related to body weight and height measurements, reinforcing why Body Mass Index is the correct answer.
