What is considered the normal BMI range for a healthy adult?

The normal Body Mass Index (BMI) range for a healthy adult is recognized as being between 18.5 and 24.9. This classification is based on the correlation between BMI values and health outcomes, with this range generally associated with a lower risk of developing weight-related health issues, as well as optimal performance in physical and mental functions.

BMI is calculated using a person's weight and height, emphasizing the importance of maintaining a balanced body weight in relation to height to promote overall health. Values lower than 18.5 may indicate underweight status, which can lead to nutritional deficiencies and associated health problems. Conversely, values above 24.9 suggest overweight or obesity, which can increase the risk of various chronic conditions such as diabetes, heart disease, and certain cancers.

Thus, understanding and using the normal BMI range helps guide clinical assessments, encouraging patients to maintain a healthy lifestyle within these parameters.
