Calculate Your BMI
Body Mass Index (BMI) and waist measurement can give you an idea about your health risks. These tools are only suitable for people over 18.
Body Mass Index, or BMI, is a quick and simple way to check if your weight is within a healthy range, based on your height. While BMI doesn’t specifically measure body fat, there is a moderate relationship between having a high BMI and a high level of body fat.
Another way to assess if you’re carrying extra weight is to measure your waist circumference. Waist circumference is better at measuring the amount of fat around your organs. This is the fat that is linked to higher health risks.
