I think it depends more on where you're coming from than where you're at. I think there's merit to working the whole process as a solution -- diet, exercise, rest, supplements, and gear -- but most others don't. They'll insist you struggle it out until you reach a magic body fat percentage at which point the steroid god's will approve and you'll have the admiration of the community.
I don't think there's any point in running a cycle if you're not also committed to the diet change, but I don't think there's any harm in "cheating" to help get your body fat down as long as you're putting all the components together to accomplish your goal.
