I do eat white rice, not every day but probably a couple of times a week. I have never had a problem digesting it, and it is handy. I also use wholegrain rice, wholewheat noodles, potatoes, cous cous and sometimes pasta. I don't cut carbs, any time i've tried it has left me ravenous and thinking about food too much. I calorie count everything I make. I write it down and tot it up, then work out my portions x cals.
To keep me full:
I eat a late breakfast, I wait until I am hungry which is normally 11ish. Nearly always porridge with a banana mashed into it
For lunch and dinner, I try to cook a big pot of something a few days a week, that will cover a few meals. So curries, chilis, bolognese (lentils instead of mince) - stuff that is easy to portion out and reheat. I use a variety of veg in all of these, but my staples are onion, peppers, cauliflower rice. Then I add whatever else is in the fridge.
I will caveat the following by saying I know this isn't the healthiest option, but works for me and my time constraints at the moment (and they are tasty)
I am using a Aldi plant based frozen food at the moment. So I will have my curry or whatever, and add in a chopped up chicken-style burger or their meatless balls. Add in some cous cous or rice and it's a filling meal. I tend to do this for dinner. For lunch, I won't add the extra Aldi stuff.
In the new year, I am going to ease back on the Aldi stuff and go back to healthier options like tofu, chickpeas, kidney beans, less processed things like falafel.
Lunch at 1pm
I don't snack much, I have an apple mid afternoon.
Dinner around 7pm
I don't know if that is helpful
I am genuinely not hungry on 3 veggie meals a day. The carbs keep me full.
I have noticed that alcohol, even a small amount, makes me hungrier the next day. So I don't drink much/often any more. Same with a meal out, I think it sends my blood sugars a bit haywire. A couple of days back on track and it settles down again.
