The Body Mass Index or BMI, is used to indicate whether you’re a healthy weight for your height.

BMI can be divided into several categories. Being overweight or underweight can increase your risk of health problems. Taking part in regular physical activity and enjoying a balanced diet can help you maintain a healthy weight.
