I know to ignore BMI.  (But, on a bragging note, I'm finally no longer obese on the tables).  And, given my frame, I'm not sure what I should weigh.  So, I did some quick math.

I weight 201 lbs, and my scale tells me I  have 25.6% body fat.  Assuming that is accurate, that means that I have 51 pounds of fat, and 150 pounds of non-fat.  Assuming that 150 is my non fat true weight, and using the WHO tables, who state that my %BF should be between 8-18%, that means that my weight should be:

8% BF: 163

18% BF: 183

Does this sound right?  My math was as follows:

NonFatWeight = Total Weight – (Total Weight * %BF)

So, current weight: 150 = 201 – (.256 * 201)

And, the ideals give the above numbers.  Is that math close enough for a goal?  Or, should I be doing it some other way?
