I've been doing it for a while now, and have made quite a few recipes from the Low Carb Gourmet. It's available online here : http://books.google.co.uk/books?id=qn_sPNKHOXkC&printsec=frontcover&dq=low+carb+gourmet&source=bl&ots=mtU5HzEBTI&sig=ujgHf0sdVMp-pr29bp_dzI9SKUE&hl=en&ei=TXajS7SkJpO7jAf7w7n8CQ&sa=X&oi=book_result&ct=result&resnum=4&ved=0CBwQ6AEwAw#v=onepage&q=&f=false
great book!
I don't find it that hard as you still get the bit I really like (the MEAT) and then you can get some tasty side dishes. I don't do any pre-packaged low carb stuff at the moment, but know that low carb tortillas and pastas are available.
You'll find a lot of your recipes are fine with minor tweaks, but the side dishes get you, I found it hard to get around having meat + veg without potato or rice or something, but you get used to it as there's loads of tasty low carb side dishes
My low carb side dish staples (remember on low carb you need to balance your fats, I found that so hard, suddenly adding cream and butter to stuff after a lifetime of 1cal oil sprays and deathly thin low fat margarive, but it really works, I'm down over 50lbs in total)
Cauliflower Rice - grated cauliflower that you stir fry in a pan with a little butter or olive oil, add a beaten egg, peas and scallions to make low carb egg fried rice

Cauliflower mash - even better spiced up with some mustard, or with butter/cheese
Low carb cheese sauce - to make low carb cauliflower cheese or broccoli
Creamed leeks, leeks cooked soft in butter, touch of cream and some cheese.
Creamed spinach, sauteed spinach with garlic, add parmesan and cream cheese
Salads, I eat a lot of salads and if I need the fat intake with dressings like blue cheese or caesar (check the labels to make sure there's not loads of sugar or god know what in these if you aren't making them yourself)
Stews and soups are a good one.
Stir Fried brocolli
Courgettes, I like them all ways, thin sliced quick with parmesan is good
There's a low carb thread in Shrinkers, if you're ever in there

Main dish examples:
Chicken "breaded" in parmesan
Fritattas! Great for breakfast but really good all the time, even cold sliced in a wedge with salad
Sag Paneer as a side dish with your curry or as a main course on it's own (you can make low carb onion bhajis if you're inclined

)
Most types of Stir Fries, just watch the sauces. Sweet and Sour sauces are basically sugar syrup a lot of the time.
Lemon Chicken (chicken quarters, lemon weges and garlic) tray bake (with loads of roasted veg)
Steaks with cauliflower mash and sauteed spinach
Pork chops with creamed mushrooms and green beans
Track your carbs with spark people when you first start, and be religious, stuff like coffee, garlic etc all have carbs in them..
