For a while I was eating more on workout days, and less on non workout. I was getting a more cut look, but I felt that my lifts were being affected. Now I just eat more or less the same amount everyday, with 1 or 2 days of eating whatever just to stay sane. Depends on what you want I suppose. If you want the covermodel look you will have to eat less and accept that performance will probably go down a bit.
