Calculating body mass index (BMI) is a crucial health assessment tool used to determine an individual’s weight status. It is expressed as a number that categorizes individuals into different weight groups, ranging from underweight to obese.
BMI plays a vital role in monitoring overall health, assessing obesity risk, and developing personalized weight management plans. Its historical evolution dates back to the early 19th century when Adolphe Quetelet developed the Quetelet index, which later became known as BMI.
