Hiya Lucy,
do you guys have a refirg at work or a place where you can store snacks? If you're running late at work and you're starving, have some snack packs of celery, mozarella cheesestick, jerky, lunchmeats, or even peanuts around so you won't be too tempted to go to the carbs. Chicken wings are OK, I won't worry about it too much. If you know it has little or no carbs, and you're in a bind, go for it.

hope that helps,
Manolo
