Body Mass Index (BMI) is a measure of your weight in relation to your height. It is calculated by dividing your weight (kg) by your height (metres squared).
The World Health Organisation (WHO) considers a BMI over 25 as being overweight and a BMI >30 as obese with 3 different classes of obesity. Elevated BMI can put you at increased risk of heart disease, high blood pressure, high cholesterol, stroke, type II diabetes, gall bladder disease, osteoarthritis & joint problems, sleep apnoea & snoring, certain cancers and premature death.
