## Risks of being overweight

These difficulties are tied to the fat and overweight

A BMI of greater than 25 (overweight) or a BMI more than 30 (obese) have a risk of diseases and health conditions, including,:

## BMI History

Body Mass Index Prime is method of using the results of the BMI calculations to 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

Body Mass is actually calculated thusly:
• 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.
