What does a normal body mass index (BMI) range signify?

A normal body mass index (BMI) range signifies that an individual has a healthy weight in relation to their height, which is crucial for overall health and well-being. The range of 18.5 to 24.9 kg/m² is recognized by health organizations, including the World Health Organization (WHO), as the standard for normal weight. This classification indicates that individuals within this range are at a lower risk for health issues such as cardiovascular diseases, diabetes, and certain cancers, which are often associated with being underweight or overweight.

Understanding BMI is valuable for assessing body weight relative to height, aiding health professionals in identifying potential weight-related health problems. The other ranges listed do not represent a healthy normal weight; for instance, values below 18.5 indicate underweight, while values from 25.0 and above indicate overweight or obesity, which can lead to various health complications. Thus, the significance of the correct answer lies in its association with optimal health and reduced risks of chronic diseases.
