It takes time to wean yourself off sugar,@magneticmoon but it's definitely worth persevering. Can you try some of the recipe suggestions in Mark Hyman's book. Very simple but satisfying meals.
I have replaced breakfast and lunch with brunch, which I normally eat around 10.30-11. I normally have a 2-egg omelette incorporating a sizeable portion of spinach, mushrooms or peppers - or whatever vegetables I have to hand (often leftovers from last night's dinner). This is so, so filling that all i need is a mid-afternoon snack of carrots, an apple or some cantaloupe.
Followed by dinner consisting of protein (chicken, fish or prawns) plus lots of vegetables, and only a tiny amount of healthy carbs. Around 25-30% protein, 10-15% carbs and 55-65%, vegetables. (NB: eggs and lentils/chickpeas are also useful sources of protein, and the latter are an excellent substitute for refined carbs.)
I also have a square or two of dark chocolate if I 'need' something sweet. But beating the sugar addiction is definitely THE key factor!
I try not to eat anything after 7 pm or within 3 hours of bedtime. Drinking a lot of water is also really helpful. Quite often, when we think we are hungry, we are actually dehydrated.
