Hi and welcome,
I used to love veg, it was the mainpoint of my meals, but then I got an tummy upset a few years ago, and had to stop eating all fibre... and without carbs... well, that just left protein and fat.
now (over 2 years later) I think my guts could adjust back up to some veg, but frankly, I don't see the point. They certainly look pretty, but my tastes have adjusted a lot. Salad is all cold and wet and odd explosions of flavour. Cooked veg now smell revolting to me - including all the cabbage family. When my husband cooks broccoli I throw open every door and window. Yet I used to love them! lol.
And after so long without veg, I certainly feel OK. I eat a wide variety of meat, fish, eggs and cheese, and stick to roughly keto macros. I love the tastes and textures, although finding a good crunchy food can be a challenge (pork scratchings and crackling are an excellent option for that).
Because of my gut issues, I take a few supplements (especially with the coronavirus around and wanting to have my immune system working in tip top fashion), but my guts are sooooooo much better without fibre that I realise I must have been having problems for years before giving up on the veg.
Anyway, you asked how to manage without veg or carbs.
Here are some suggestions:
Lidl's do a protein noodle that is v low carb. Oomi do a similar product. they make an excellent pasta sub
There are some low carb breads and bread recipes out there. Also some bread mixes that you just add water to. There are even carnivore pizza recipes out there.
I seem to enjoy food more if I have a variety of things on my plate, so when I can be bothered, I like to serve 2 or 3 different foods rather than just 'steak'. So think steak, with an egg and a few garlic chilli prawns, or a blob of pate next to a chicken breast, with bacon rashers (which is really just a deconstructed version of the chicken breast stuffed with pate, wrapped in bacon, that my butcher preps, and then charges absurd amounts for one breast).
IF you want to continue with veg, you can try things like cauliflower rice, or mashed cauliflower, both of which make good substitutes for rice and potato mash. But personally, I can no longer get past the smell.
Oh, and mushrooms... mushrooms fill a rather odd niche between veg and animal products. You may find them a useful addition. But it depends entirely on your tastes.
And herbs and spices are your friends.
One thing I will say - our food bills dropped sharply when I went carni.
V curious. I had thought it would be the other way round.
If you are going to do carni seriously, then I suggest you do some proper reading on the subject.
Lots of info out there nowadays, some rather OTT and zealotous, whereas some is very sensible and helpful.
There is no reason why carni can't be a reasonably priced, sustainable, healthy way of eating, despite knee jerk reactions from people who haven't tried it properly.
Personally, my nutrition and digestive health is better than for the last 10 years, now I have stopped upsetting things with veg, and have sorted out the malabsorption that I used to have.
Oh, and I still eat small amounts of dark choc, and the odd bit of garnish, or raspberry, just not every day, and always in controlled portions. Well, except the choc. That isn't always rigidly controlled
