On a serious note boys, and girl, I don't think there is any literature out there that proves that protein intake before sleep reduces protein catabolism. What keeps weight is a positive balance of nutrients in the body, what loses weight is a negative balance of nutrients in the body. What keeps the body healthy is healthy food intake. You are what you eat, so keep it clean and your body will respond by hanging on to that hard earned muscle. If a protein shake just before bed brings your daily food intake just above the maintainance level, you will prevent loss of muscle. However, I maintain that the same could be acheived by eating that same amount of calories and stopping 5 hours before bed, you'd just be really hungry, and pissed off before bed. The most important thing is to eat clean, and well balanced, the body isn't designed to take in 500 grams of protein/day and it simply can't digest all that, but trying will tax your body, and make you feel shitty.
just my .02
Cheers.
