Body Mass Index Calculator: this calculator will give you an idea of how your weight compares to common values. Body Mass Index (or BMI) is calculated as your weight (in kilograms) divided by the square of your height (in metres) or BMI = Kg/M2. This calculator should only be used by adults (pregnant or lactating women should not rely on these BMI readings) and no action should be taken based on its values other than to consult a suitably qualified person such as a physician. About a fifth to a quarter of adult body weight is made from white adipose tissue (see an image of fat cells). However this proportion can be lower in lean individuals and it can rise dramatically in obese individuals. Obesity is now a major health problem in the West. Some studies suggest that the obesity epidemic is linked to a viral infection. Obesity can predispose to heart disease and diabetes. Body Mass Index or BMI can give an idea of the weight category that a person is in and so can have some predictive value. Diet and excercise can help to control weight but all changes to your life style should be discussed with a qualified person such as your GP (physician). DISCLAIMER: this calculator is for interest only, it does not replace a consultation with your health care provider.
