One has to consume X g of Protein of his X pound of body weight.

Does this apply to work out day only or everyday?

Normally people take more protein on workout day but not on non workout day, I wonder why? On non workout day, the muscle is being repaired, so it needs protein too. I remember that someone said, the muscle grow when it rest but not when you workout.

From this statement, I THINK that protein consuming equally important on both workout or non-workout day. Anyone please comment?
