BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It's calculated by dividing weight in kilograms by height in meters squared.

What is a healthy BMI range?

According to WHO standards: Underweight: BMI < 18.5, Normal weight: BMI 18.5-24.9, Overweight: BMI 25-29.9, Obese: BMI ≥ 30

Is BMI accurate for everyone?

BMI has limitations. It doesn't distinguish between muscle and fat mass, so it may not be accurate for athletes, elderly, pregnant women, or children. It's best used as a screening tool alongside other health assessments.

Understanding BMI

Body Mass Index (BMI) is calculated by dividing an individual's weight in kilograms by the square of their height in meters. It's a widely used measure to assess whether a person's weight is healthy for their height, but it doesn't directly measure body fat.

Clinical Considerations

BMI doesn't differentiate between muscle mass and fat mass, so it may not be accurate for athletes or individuals with high muscle mass, according to the CDC. It also doesn't account for factors like age, sex, or ethnicity, which can affect body composition.
