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. There is a charts available on line to refer to or you can work it out yourself. Divide your weight in kilograms by the square of your height in metres, or divide your weight in pounds by the square of your height in inches, then multiply by 703. A BMI of 25 to 29.9 is considered overweight and one of 30 or above is considered obese. People with BMIs between 19 and 22 live longest. Death rates are noticeably higher for people with indexes 25 and above.

The body mass index (BMI), is a measure of body weight based on a person's weight and height. Though it does not actually measure the percentage of body fat, it is used to estimate a healthy body weight based on a person's height, assuming an average body composition. Due to its ease of measurement and calculation, it is the most widely used diagnostic tool to identify weight problems within a population, usually whether individuals are underweight, overweight or obese. It was invented between 1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of developing "social physics".

BMI (body mass index) is a screening tool used to measure weight relative to height. While BMI does not measure body fat directly, it has been shown to correlate to measures of body fat, such as underwater weighing, and is considered an accurate alternative for body fat measurement. With a simple formula, you can calculate your own BMI.

How Is BMI Calculated?
To calculate your BMI, you will need to divide your weight in pounds by your height in inches squared and multiply that by 703. The formula is: weight / [height (in inches)]2 x 703

Consider the following example:

April is 5'5" and weighs 150 pounds. She completed the formula as follows:

* First, April figures out that her height in inches is 65". ...more

It is a chart available with Doctors-it gives certain limits for a particualr sized body, for eg: at the age of 25 years - he should be 1.67 cms height, chest should be 36 inches unexpanded, weight 52 kgs so on, it is given so that no person gets anytime higher weight than mentioned in the chart, otherwise he is considered fat/more cholestrol.
