So, it seems that nobody that's responded to this thread knows anything about protein metabolism (especially SD). In case you guys are wondering, the size or musculature of one making an argument has nothing to do with their argument (see tu quoque fallacy).
About protein: I'm not up to snuff on what level can be absorbed in a single bolus, but it's affected by factors such as how its cooked, source, etc. The relevance of "pissing it out" once you get to a certain intake is a simplification of the truth. Your body has a circulating amino acid(AA) pool (~100g if memory serves me right), once the body's ability to synthesize protein is met, the excess is deaminated. The resulting carbon backbone of the AA is shunted into energy metabolism (via anaplerotic reactions) and the nitrogen is excreted in the urine (mostly). One must also consider the protein quality, as lower quality or 'incomplete' proteins will have key amino acids that will allow protein synthesis to occur to the level of that limiting AA. If the AAs can't be used for synthesis, they are used for energy.
Protein recommendations: The established recommendations for athletes (1.2g/kg) are designed to MAXIMIZE SYNTHESIS, therefore, consuming far above that level would be unnecessary for most, especially when consuming high amounts of carbs. When trying to lose weight, protein turn over is higher and your intake should be adjusted to accommodate for that (still be a marginal increase). So, these recommendations of 1g/lb of body mass or stupid amounts like 300-350g/day are fucking retarded and unnecessary. If you like to waste your money on eating a shit ton of protein when it's not going to serve any benefit (and likely put you at higher risk of disease in your future), go hard.
