What is a good BMI for males? A measure of body fat based on height and weight, body mass index (BMI) is a useful indicator of overall health. For example, a BMI between 18.5 and 24.9 is considered healthy for men.
BMI is relevant because it can help identify individuals at risk for weight-related health problems, such as heart disease and diabetes. Additionally, BMI has been used in research to study the relationship between obesity and mortality.
