Needsize, cheat a bit (one bad meal a day) is fine when bulking, and even up til probably the last 8 weeks of a contest diet for most, but white floor is still not good for you. It increases the chance of diabetes later in life, can reduce insulin senstivity over time.
While it is fine, I'm just saying that you could get better nutrition for your $ with rolled oats or barley if the issue really is price as you said. However, I suspect, it has more to do with just wanted to eat something you like. WHich is fine. I eat pizza at least twice a week right now, and seem to be getting leaner from week to week since my diet is very strict outside of my occasional cheat throughout the week.
