Paleo recipes might be helpful. I really like the recipes from Elana’s Pantry because she thoroughly tests and re-tests her recipes to make sure everything will come out as expected. Her almond flour based baked goods are low carb (but not quite keto levels) and she focuses on using simple, readily available ingredients.
Here’s one of her cookbooks: https://www.amazon.com/Paleo-Cooking-Elanas-Pantry-Gluten-Free-ebook/dp/B00ATLAAK0/
In general, I focus on limiting carbs and will often just have extra vegetables at my meals instead of a carb side like rice. The Banza chickpea pasta is pretty tasty and very filling (has a kitchen scale to weigh out a portion before cooking - overeating it can cause tummy issues if you’re prone to that sort of thing). I’ve used the Banza macaroni to make diabetic-friendly pasta salad in the summertime, as well as just using that whenever I would have other pasta. Follow the cooking instructions, which include rinsing it after draining. It smells funky while cooking but tastes fine cooked.
I also eat a fair amount of quinoa. Getting it in bulk from Costco has been the most cost effective.
Personally, I find cooking from whole foods (not using premade components in meals) to help a lot with limiting carbs, because then you’re in complete control of what is going in your body. But it’s a lot of work - not just cooking, but planning for meals and grocery shopping - to do that all of the time.
When it comes to fat, I’ve found I need more in my diet to feel satiated between meals and avoid blood sugar drops. If I’m having dairy products, I make sure they’re full fat.
