Is there a limit to how much protein the body can use in a single meal?

There are many controversial subjects in the world of bodybuilding, but probably none that give a more varied range of answers than the good old 'What's the maximum amount of protein that can be absorbed in a single sitting?'

It's gotten so bad that there are meatheads everywhere designing their whole diet around what they believe to be the right limit, but are there efforts in vain?

We needed someone that can apply both science and logic and answer this question once and for all and who better than Mr Alan Aragon....
