Check my BMI

If you are carrying excess weight, you are storing up trouble

These dangers are identified with overweight and obese adults

People with a BMI of greater than 25 (overweight) or whose BMI is greater than 30 (obese) have an intensified risk for many diseases and health conditions, including,:

• Hypertension (inflated blood pressure)
• Coronary heart disease (plaque build-up along the inner walls of the arteries of the heart)
• Osteoarthritis (degenerative joint disease)
• Sleep apnea and respiratory problems (problems breathing during sleep, chest and lung problems)
• Stroke (loss of brain function due to a disturbance in the blood supply to the brain)
• Dyslipidemia (elevated LDL cholesterol, reduced HDL cholesterol)
• Diabetes mellitus type 2 (high blood sugar)
• Gallbladder disease (gallstones, disruption of bile functions )
• Some cancers (endometrial, breast, and colon)

Derivation

BMI Prime is simple way of defining a single figure that is not immedieately related to any other units of measurement, but which can quickly and easily rank a person into a category. :Eg:

• BMI Prime < 0.74 = Underweight
• BMI Prime > 0.74 and < 1.00 = Optimal weight.
• BMI Prime > 1 = Overweight

BMI, sometimes known as the Quetelet index, is a measure used to estimate a person's body shape based upon a person' weight and height. It originated in Belguim around the 1840's by Adolphe Quetelet. It is a simple calculation based on the individual's body weight divided by the square of their height.

The formula

This is how BMI is calculated

• BMI = weight(kilograms) / height² (metres²)         (Metric Units)
• BMI = 703 . weight(pounds) / height² (inches²)         (Imperial Units)

BMI limitations

BMI is particularly inaccurate for people who are very fit or athletic, as their high muscle mass can classify them in the overweight category by BMI, even though their body fat percentages frequently fall in the 10-15% category, which is below that of a more sedentary person of average build who has a normal BMI number.
