Big difference is hard cheese is nutrient dense and leave me without hunger for a far longer time than empty calories simple carbs that basically bypasses the body checks. Lot of times when I am hungry my body just wants protein. 1000kcal of sugars can leave me hungry after one hour. I eat ton of 80% chocolate and hard cheese and don't get any weight. On the other hand with simple carbs and white flour based things (pasta, bread, pastries...) I have to consciously limit myself to a few per weeks otherwise kg starts piling on fast again.
