i think you guys have pretty much said it all. But there are two sides to this story, i am cutting or trying to gain size. obviously when cutting you need to keep protein higher to spare protein and deplete to get dry and shredded. when training hard you need the carbs higher to train which will also spare protein. so portein can then be less. bottom line is protein is the best to err in the over side. if you err in to much carbs or fat, you are guranteed new storage of water and fat. if overboard in protein you still have options. (gluconeogenesis, energy, excretement, storage.....)
