There are a couple of things that you might like to consider.
Resistant starch - If you cook potatoes, pasta etc and then, once cold, put in the fridge overnight then when you re-heat, you will have reduced significantly the amount of nasty carbs and no one the wiser.
Disguise the veg. I got good at this with my children and grandchildren. For example tonight we are having stuffed ham:
Beat eggs, scramble in butter season with s and p, adding grated cheese, chopped tomato, then cooked mushroom, then fold in some baby spinach and chopped parsley. Now put mix onto slices of ham, roll up, put in a dish and then under the grill until the ham starts to brown - what's not to like.
As previously mentioned, look up some scrumpy LCHF recipes and just put them on the table.
You are doing so well. Keep smiling.
