Instead of focusing on sugar being bad, and avoiding it - focus on protein being better, and seeing sugar (and other carbs) as merely filler. Most carbs and fats exist to extend the savory flavor of protein (umami), such as gravy, or fries. Or the carbs act as a scaffold to hold the protein and other elements, as in the case of a sandwich or sausage bun. Once you start looking at foods in this way - in terms of proteins, other nutrients (vegetables), and filler (carbs and fats) - it's easy to target foods high in protein and nutrients, and low in filler. This doesn't mean avoiding junk foods, but it gives you an excuse to not eat pizza crust, and means you'd target thin crust, or even opt for chicken strips.
