Can you have plain air popped popcorn with the special k diet?

Im going to do the special k diet starting the 9th. I was thinking about getting a air popper for popcorn. I have drastically changed my whole lifestyle. Im 20 years old. I used to be 232 lbs I am now 162. I want to get down to 135 lbs so im almost there. I do hip hop abs twice a day along with simple exercises.Will I lose weight on the special k diet if i incorporate plain air popped popcorn with it? All the help and advice I can get would be very much appreciated.
