BMI - Fitness Meter

Doctors use the body mass index (BMI) as a simple way of assessing whether a patient needs to lose weight. The calculation is based on comparing a person's weight with their body height. It applies equally to men and women. As BMI is based on weight and height, by losing weight you will reduce your BMI and put yourself into a lower risk group. A healthy diet, including a balance of food groups, vitamins and minerals, is essential for a long and active life. Keeping it simple, body weight and shape are a balance of energy intake (dietary calorific content) against output (calorific burn from activity & exercise).
