Well let me put it this way, I would do cardio like a mad man (60-90 minutes intense) and down a six pack later in the evening. Literally, that hot burning feeling you get all night from your metabolism being raised from that workout, goes from hot to cold within a few hours from all the calorie consumption. But honestly, I've been cutting down a lot lately, and have stayed away from any beer intake except this past weekend.. Drank a 6 pack and it did nothing to my physique. Sure, in my mind, I'm thinking I could have been burning off calories over night, but some times you have to take a mental cheat day and that's what it is for me. Mon-Friday - good behavior. Saturday - Sunday, normal meals, back to diet. Yes, the more you abstain the better and quicker you'll accomplish your goals.
