Body Mass Index, BMI, is a ratio of your weight to height, it's used as an indicator of body fat. BMI is an inexpensive alternative to direct measurements of body fat, such as underwater weighing or bioelectrical impedance, but is one of many factors that is used in evaluating your health status.

Calculating Your BMI
You can calculate your BMI with this formula:
Weight (kg) / [Height (metres) x Height (metress)] 

BMI is used to define terms including overweight and obese:
Underweight: BMI below 18.5
Normal weight: 18.5 to 24.9
Overweight: 25.0 to 29.9
Obese: 30.0 and above.

People with a BMI outside of the normal weight range may be at the greatest health risk. Those who are considered to be underweight may not be getting enough calories or receiving adequate nutrients, putting them at risk for certain health conditions. Whereas individuals with an overweight or obese BMI tend to be at increased risk for high cholesterol, diabetes, heart disease, sleep apnea and some cancers.

However, BMI is only one factor in your overall health. Eg, if your BMI falls into the normal weight category, you are still at a higher risk of health problems if you:
-Do not participate in regular physical activity
-Choose foods low in vitamins & minerals and high in saturated fats & added sugars.

If your BMI is in the overweight category, you will have a lower overall health risk if you:
-Get regular exercise
-ideal blood pressure, cholesterol & sugar levels.
