This is always going to be the same, just over 4.2 joules. The amount of calories you used was less after excreting the excess, but the calorie measurement remains constant.

As far as measuring how much you need I intend on starting a month long process in October where I try various amounts of protein intake and then I measure the amount I am excreting in my urine and study the trend and compare to established norms. I have access to a lab so I look forward to seeing if a diminishing return will the present in the data.
ok, how about this....

Your body's ability to efficiently burn a calorie depends on the source of that calorie and the rate at which that source is being consumed. With protein, there is a point of diminishing marginal returns to where each additional gram of protein produces fewer and fewer utilizable calories, until we get to something like 1.5 grams of protein per pound of LBM, and then at which point, the body becomes "overwhelmed" and is no longer able to process all the protein, thereby eliminating any further excess.....?
