I am doing no sugar, no flour. What and how often do you recommend a joy food treat?

I understand the planned, no eating in response to urges, but why would I still plan to eat sugar as a joy food? (Dessert has been my go-to joy food. I could eat something else but not sure it would really feel like I ate a “joy” food. Should I just concentrate on enjoying my fuel food and skip the joy eats except for rare, special occasions that are pre-planned.)
