1. I'd guess so, but I haven't checked the label. Aren't these almost calorie free? If so, then it should be fine.
2. Cheat meals would be best counted as your "carb" meal. If you're going to eat half a pizza, don't have carbs at any other point of the day (except pre/post workout). That isn't Adam's recommendation, but if you think you NEED a cheat meal...
