@samthebordercollie I do eat carbs but not generally the refined kind. The most refined type I eat is white rice - we've got loads of white rice, once that's gone I'm going to try to switch to wild rice. I also eat potatoes, quinoa, oats & buckwheat. Usually have a couple of tablespoons per meal, or about 2 oz ish. Not currently eating wheat or rye, nor any type of gluten free bread as I don't like them. I do plan to get some spelt sourdough, when I can get hold of some though, as apparently that's low enough. Bit nervous as the last time I tried reintroducing wheat after excluding it, I was in pain for a month, but it was just regular wheat noodles... so we'll see.
I don't have much added sugar at all - I don't have much of a sweet tooth, prefer fruit. I only like really dark (expensive) chocolate & I'm not currently allowed much of it. Nor much fruit. I'm also virtually lactose free at present which is a pain as I usually eat loads of yogurt, however I'm allowed small amounts of cheese if the carb content is under 1% because it's low lactose.
I am going to try to eat more oily fish, & a lot less meat. I don't even like meat that much, I only eat it because it's easier as DH won't eat vegetarian. I used to be vegetarian.
Re: portion control, I've been making batches of food, rather than individual meals IYSWIM. I serve some up, cut up a load of salad, & eat it. If I'm still hungry a while later, I get more. But I don't feel like I have to put the whole pan full on my plate or waste it, because I'm deliberately making more than one serving of some things at the moment. Also, it saves time & dishes, & I don't have the oven/hob on as much in this hot weather.
