as far as cravings - that's a bit strong of a word but here are some things I missed and was glad when I found a substitute:

* there's a really good pizza recipe that is just cheese for the crust. amazing. Its better than regular pizza, really.

* lasagna/spaghetti you can use zuchini or spaghetti squash as noodles, and can eat in a bowl (just a tad more soupy), still tastes great (again, I love italian)

* I went through a phase where I ate cheese crisps (microwaved cheese, super yummy like crackers) and made flaxseed wraps (like bread). I don't make either any more, just pointless work.

* Pork rinds are amazing - good with soup, like a cracker, like croutons for a salad, with guacamole, nachos, hummus, or peanut butter. (note that the last two are easy for me to indulge on, I just have to watch)

* I Make 24 eggs at a time as a fritatta, make a pork shoulder in the oven, braised chicken thighs, oven roasted whole chicken, big batches that have many servings.

* I used to eat cereal every day, I but got over that quickly enough - now it's just 2 eggs each morning (slice of fritatta).

* I like hamburgers, but usually just eat them plain with a few pickles on top. less messy, and frankly you taste the meat more.

* I gave up beer completely, which I used to drink with pizza. Now its just red wine once in a while.

I don't go out to restaurants much because frankly we have better food at home and admittedly they're not usually low carb oriented. But you can always get a burger without the bun. Or a gyro plate. Mexican fajitas (hold the tortillas and chips) are a winner too.

I started off reading the wheat belly blog, and after I lost 10 pounds I bought his book. I also recommend "The art and science of low carb living". There's also great vids on youtube of atkins & LCHF stuff. I also read william banting's old pamphlet for inspiration.
