Body Mass Index (BMI) is a measurement used to assess whether a person is at a healthy weight in relation to their height. The BMI formula is quite simple: divide a person’s weight (in kilograms) by their height squared (in metres). Although BMI is not a perfect measure and does not take into account factors such as body composition (e.g. the difference between muscle mass and fat mass), it is widely used as a quick screening tool. Keeping your BMI within a healthy range is important for reducing the risk of a number of diseases, including heart disease, type 2 diabetes, high blood pressure and some types of cancer.
