The Body Mass Index (or BMI) is a way of seeing if your weight is appropriate for your height. The actual
calculation is your weight (in kilograms) divided by your height (in metres) squared but it's also easy to read
on the chart. BMI can be divided into several categories and generally the higher your BMI, the greater your risk
of a large range of medical problems.

Inaccuracies can also occur if you're an athlete or very muscular as this can give you a higher BMI even if you
have a healthy level of body fat and this BMI chart is not appropriate for women who are pregnant or breastfeeding,
or people who are very frail.

As BMI is based on weight and height, by losing weight you will reduce your BMI andput 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).

Many studies have shown that, to slowly and steadily lose weight, any diet which includes a healthy balance will work
if you're motivated. Generally, to lose 0.5kg/week you need to take in 500 calories less every day.
