There's no need to apologize for your ignorance: there are not very many varying factors, at all. You measure the fat with the calipers, add up the numbers, look at the chart, get the percentage, then do a teeny tiny bit of math to figure out how many pounds of fat you lost from your total weight loss.
Not very difficult, at all. Not many "factors" to account for, using that method. It's a very tried and true method. However, I will admit that it does not work for the morbidly obese: they have too much fat to get an accurate measure with the calipers. I think with the morbidly obese, you have to do the water tank submersion measure (which is generally seen as the most accurate possible way of getting a bodyfat measure).
Edit - Here's a nice quote for you: "Under ideal conditions, caliper tests predict fat percentage within plus or minus 3.5 percent of your true body composition, as defined by ACSM." That's decently accurate. It gets much more accurate when you drop below 12% bodyfat because there is almost no subcutaneous fat to account for in the measurement (which is usually what gives you the 3.5% variance).
Anyway, I hope you've learned quite a bit from our discussions. Here's a recap:
Bacon and cheese can be part of a healthy diet.
Keto-diets are clinically proven to be effective fat-loss approaches.
Bodyfat calipers can give a fairly decent measure of your bodyfat if done properly.
Time Immemorial definitely definitely knew, prior to this thread, that I both work out and eat healthy from prior conversations in the Movie Versus Forum.
