The problem with protein bars is that you don't really get full. You just get tired of chewing. It's a lot like eating crab legs. Though the process of eating them may appear haphazard—nay, even barbaric—it actually requires a great deal of dexterity. Unfortunately, the reward for all your painstaking labor is a tiny amount of meat, succulent though it may be. You actually weary of eating before you get full. It's as though you were forced to solder miniscule components onto a circuit board, and were rewarded for each piece you attached with a single Cheez-It.
