Obesity is defined as the excessive accumulation and storage of body fat, usually measured by the body mass index (BMI) system. Your BMI is a body weight to height ratio and is calculated by dividing your weight (kg) by the square of your height (m). Refer to the online BMI calculator to work out your body mass index. While the BMI is not the most accurate method of assessing weight management problems, it is nevertheless the universal measure of assessing a healthy body weight.
