Try at first for a cheat meal. As you progress in your cutting then you may go the route of cheat day. But even then you want to be smart about it and not ruin your progress. As eating pure shit can.
As you begin to stall out its a good idea to do a carb load. Go about 2k over your maintenance cals and make your meals consist of primarily carbs.
Bonus, sugar is not only ok but good too, in moderation.
