Is my weight healthy?

Knowing your BMI may save your life

These dangers are associated with overweight and obese adults

Adults with a BMI of more than 25 (overweight) or whose BMI is higher than 30 (obese) have an increased risk for a number of diseases and health conditions, including,:

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

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

Calculate your BMI and tell you if you are underweight, overweight or if your weight is optimal. Just enter your vital statistics and click the button. The results will be graphed out for you.

Formula for BMI

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 proportional to the mass and inversely proportional to the square of the height. So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same. This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels.
