And if you're doing low carb pretzels & apples are just about the worst thing to eat! There are better options:
--almost any kind of nuts. Macadamias, believe it or not, while highest in fat are lowest in carb when it comes to nuts (OK girls, I know you want to, go ahead w/your comments

)
--celery with cream cheese or peanut butter. Cream cheese = zero carbs, peanut butter about 7 carbs per tablespoon.
--veggies like celery, carrots, cucumbers, broccoli, etc. w/some kind of dip. If you make your own, mayonnaise is zero carb. If you buy it, make sure to check the carb content on the label.
--Cheese, cheese, cheese! Pretty much all cheeses are zero carb.
