I started Atkins last summer and went to the movies 3 or 4 times. I couldn't stand pork rinds at the time (now I love them!) so I brought in a protien bar. I also ate a big meal before going. The smell of the popcorn which I use to love really turned me off. You may be surprised. If you are not craving carbs anymore the smell may have no affect on you. But just in case, make sure you bring some legal snacks. That's my 2 cents worth!
