Wasn't sure anyone would catch the reference.
Yeah I have read that as well and if you aren't losing much muscle then you're probably on track. I shoot for 1g per lb of lean body mass but I don't always get there, especially when I'm cutting, but I don't go below .8g per lb of lean body mass. And I know this works for me. I don't lose too much muscle this way. But I'm a mesomorph so I gain fairly easily. Another thing is when I'm cutting I try to stay away from the protein powder, due to cost, and just try to get all my protein from food. One more thing, you don't excrete excess protein. If protein is not used to maintain the body or as energy it too will be turned into fat.
