What is BMI?

BMI (Body Mass Index) is a measure used to evaluate if a person is within their ideal weight relative to their height. It is widely used by health professionals as an initial indicator of body composition.

How to calculate BMI?

The BMI calculation is done by dividing weight by height squared. Although simple, it provides a good estimate to identify potential weight-related risks.

Is BMI reliable?

BMI is a useful tool, but it does not take into account the amount of muscle mass. People with high muscle mass may have a high BMI without being overweight in terms of body fat.
