I guess it depends on how you go about it. If, say, I ate 1900 calories a day six days a week so I could have 2600 calories on Saturday, that seems like something that wouldn't make me feel too deprived vs. just having 2000 calories every day. There inevitably are going to be days when we eat a bit more, planning them in instead of experiencing unplanned cheats could be less stressful.
