Body Mass Index (BMI) is a measure of body fat based on your height and weight. The BMI is suitable for adult men and women over 18 years of age. It is calculated by dividing your weight (in kilograms) by your height (in metres) squared. You can fill out the Free Diet Profile and use the BMI calculator to find your actual BMI as well as ideal weight in a few quick and easy steps. The BMI chart will also provide you with a visual representation of where you lie in terms of your target weight.

Once your BMI has been calculated you will be able to determine whether you are within the healthy weight range for your height. A calorie counter will calculate how many calories you should be eating to maintain/gain or lose weight.

BMI is an internationally recognised measure of obesity.
- Underweight BMI below 19.5
- Normal 20 - 24.9
- Overweight 25-29.9
- Obese over 30

If you have a BMI that categorises you as obese, weight loss may make a considerable difference to your fitness and health. Having a BMI above 30 means there is an increased risk of conditions such as Diabetes and Coronary Heart Disease. However the BMI calculator should not be seen as a diagnostic tool, it’s a statistical indicator of increased health risks.

As a statistical tool the BMI calculator does have certain limitations:

• Individuals that are athletic or very muscular may be categorised as overweight. A body builder may be identified as obese even though he/she is perfectly fit and healthy.
• As a person ages they tend to lose muscle, so there is a risk that the BMI calculator will underestimate the body fat of an elderly person.
• The BMI calculator should not be used by pregnant women.
• BMI does not take frame size into consideration.

On the whole the BMI calculator is a quick and reliable method to determine whether an individual is underweight or overweight. By completing the Free Diet Profile you will receive a personalised BMI profile and calorie recommendation which can start you on the road to better health today.
