These ranges can vary slightly depending on the source, but the general classifications are as follows: - Underweight: BMI below 18.5 - Normal weight: BMI between 18.5 and 24.9 - Overweight: BMI between 25 and 29.9 - Obese: BMI of 30 or higher It is important to note that BMI is a screening tool and not a definitive measure of body fat or overall health. It does not distinguish between fat mass and muscle mass, which means that individuals with high muscle mass may have a high BMI even if they have a low level of body fat.
