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,:

BMI Prime

B.M.I. 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 Prime is a variation of the Quetelet index. If you have a Prime of less than 0.74, you are underweight. If your prime is more than 0.74 and less than 1.00, your weight is ideal. If your BMI prime is more than 1 you are seen as being overweight.

Formula for BMI

Measure your BMI with the formula below
  • 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.
