Welcome to the forum - there are a lot of new people joining up at the moment all with similar confusion.
The key thing to understand is we can't deal with carbohydrates very well - those are starches and sugars.
Meat, fish, eggs, cheese, all good, low carb veges, usually above ground grown are also good for a few carbs, salad stuff too - to avoid, grains, potatoes and root vegetables, though I have small amounts of roasted carrots and parsnips along with swede turnip and celeriac, having checked with a blood glucose meter to establish that it is OK. I have full fat yoghurt, and cream.
I have a mug of coffee in the mornings with a tiny amount of salt (because I have no other source) a pinch of cinnamon, and cream - and I froth it up with my Bamix.
Breakfast might well be steak and mushrooms, maybe with a green sweet pepper and courgette tossed into the pan if it is going to be a long day out of the house. In the hot months a large salad with cheese and eggs, or tuna, or chopped cold meat is good.
Personally I find the low carb diet is no problem at all as it is delicious, and not very complicated.
