Your weight should be commensurate to your height and sex.
Use this formula to calculate your ideal weight.
For males:
Your weight should = 50 + 0.91 (height in centimeter ? 152.4)
For females:
Your weight should = 45.5 + .091 (height in centimeter ? 152.4)
If your weight is 20% above the calculated number you are considered overweight. If your weight is 50% above that number your are, by defintion, obese. In both cases, your life expectancy and your disease-free intervals are significantly decreased, up to twenty times!
