I applaud your effort here, and am well aware of how difficult it can be to change your diet, no matter the reason. I did it myself, for about 2 years, while stationed unaccompanied in Guam, only to fall back into bad habits once I came back home to the wife.
It can be a struggle at times, until you get used to it, so you might try what I did at first, to help. Stick to the diet as best as you can, during the week. Pick one meal or snack on the weekend, to address whichever craving hits you the hardest during the week. You can carefully use this as a splurge, whether it's pizza, donuts, or whatever. Just make sure you maintain portion control, and go right back to your regular diet afterwards.
Pasta. As was said above, no perfect substitute there. I use zucchini and spaghetti squash. They make these little things to allow you to make your own noodles from zucchini, or you can buy them already done, as "zucchini nests" in the frozen foods section. I believe we get our nests from Costco. I'll link a brand below that we use for pasta on a regular basis. Since we don't do things like buttered pasta as a dish at my house, it fits the bill quite nicely. It's made from chickpeas, so it has a bit firmer bite to it, similar to al dente pasta, but the flavor is very one to regular wheat pasta. If you use it, once the water boils, make sure the lid gets taken off the pot, and then place a wooden spoon across the top, to make sure it doesn't boil over.
The most delicious alternative to pasta. Celebrity chef AND dietitian approved. Changing pasta forever, for the better – it's pasta that loves you back!
You can order it from the website (I think), or get it from various stores, such as Target. I believe it's something like 2 carbs per serving.
I'm pulling for you on this, and though it can be a pain, it's rewarding, and you'll make it through.
Forgot: tortillas. Don't have any on the counter to give you the name brand, but ee use ones that have carb balance on the package, in big letters. I think the label is blue and white. Recipes, if the mods pipe in and say it's OK, I'll post a link to the website I use for a lot of keto friendly recipes. Most of the recipes have notes from the website owner, whether it's where she got it, how she felt about it, etc. As I recall, she had some of the nutrition stuff listed on a lot of them, as well, such as protein and carbs, and maybe even sugar content. If I don't see a post saying I can put the site up in here, pm me (anyone interested) in a day or two, and I'll get you the site.
