I eat very little sugar. I'd not say I'd given it up 100% but it's minimal in my diet.
I will have a treat maybe once a week.
Don't know if it will help but this is a typical day's food for me (without sugar)
Brekkie- boiled, scrambled or poached egg with mushrooms , occasionally bacon, slice gluten free bread.
Lunch (1pm)- homemade or bought (quality) soup. Or an avocado with salad. Apple or greek yoghurt.
Afternoon snack- oatcakes with almond butter, Greek yoghurt
Dinner (around 7pm) fish, chicken, stir fries, salad, vegetables, casseroles, fish cakes, roast veg/ lentil bake, cauliflower cheese etc.
I don't snack much and if I'm hungry have a few nuts- always have a bowl in the house or in my bag if out.
I have various food intolerances to am gluten free and can't eat chocolate! I never buy sweets. At a weekend we might have a pudding- crumble or something.
