BMI compares your weight to your height, and is calculated by dividing your weight (in kilograms) by your height (in metres squared). It gives you an idea of whether you’re ‘underweight’, a ‘healthy’ weight, ‘overweight’, or ‘obese’ for your height. BMI is one type of tool to help health professionals assess the risk for chronic disease. Another important tool is waist circumference. It is also important to understand your other risk factors.
Waist circumference is a simple check to tell if you are carrying excess body fat around your middle.
Where your fat is on your body can be an important sign of your risk of developing ongoing health problems. Carrying excess body fat around your middle is more of a health risk than if weight is on your hips and thighs.
