Like many others here, I want to ensure that I retain as much lean mass as possible as I lose my final XX pounds of fat. I do heavy compound lifting 2-3x a week to that end, and consume around 1g of protein per pound of LBM. I log everything daily, including weight and BF%, and smooth things out with 5 and 7 day averages. Amongst other things, this allows me to confirm my TDEE is actually pretty close to what the calculators average out to.

One of the other calculations I track daily is:

(Starting weight * starting BF%) - (Current weight * current BF%) = approximate fat loss

Currently, this is very close to actual weight loss. IE, calculated pounds of fat lost ~= actual weight lost.

Assuming my base measurements are equal, is it safe to assume that my protein intake and heavy lifting is having the desired effect? If the approximate fat loss calc turns out to be, say, 80% of actual weight loss, is that still pretty good? At what percentage (50%?) should the alarm bells be going off?
