If you are prepared for the next day's food and have lots of protein foods around, go ahead and eat some. If you make yourself eat protein when cravings to eat carbs hit, they GO AWAY. It's partly habit to crave carbs and partly, it's your body trying to give it the EASY FUEL again. So it puts thoughts of carby foods into your brain & makes you want them. Defeat that nasty chemistry and forge on toward your goal - EAT MEAT! I have yet to have a craving that could survive eating protein instead.

Good luck.
