Body Mass Index
Body Mass Index (BMI) is commonly used to classify weight in relation to height and a high BMI means someone is too heavy for their height. BMI may not be accurate in people who are very muscular like athletes or rugby players. Even people with a normal BMI can still have excess weight around their stomach, therefore BMI is best used in combination with waist circumference. BMI is only suitable for adults because children need to have a BMI score calculated specific to their age. Ask a health care professional to do this.
Calculate BMI by dividing weight in kilograms by height in centimetres TWICE.
For example: 90 kg / 180 cm = 50. 50 / 180cm = 27.8
The distribution of excess weight around the body matters. That’s because the type of fat that accumulates around the stomach area, called abdominal fat, is more dangerous than subcutaneous fat – the fat underneath the skin spread across the rest of the body. Visceral fat, also commonly called visceral fat, is more likely to cause diabetes, abnormal blood cholesterol, high blood pressure, and heart disease. Waist circumference measures abdominal fatness by a measurement in centimeters around the waist, at the level of the belly button.
