Welcome Jamie Lynne
We're happy you found this forum, there is so much good advice going back many years organized by topic. Look all around, there is a huge recipe section, lots of good information on your health conditions and especially in the dIabetes forum. http://forum.lowcarber.org/forumdisplay.php?f=45. (If you are on meds...read the advice in sticky at top!)
Same if you are on BP meds. Learn more about cholesterol in that forum.

There are special sub-forums for Buddy groups to help you, including one with tips for those who have a long weight loss journey. http://forum.lowcarber.org/forumdisplay.php?f=49
As zoogirl mentioned, some work into the lowest carb level slowly. You can read back through recent threads in these forums to find advice. Others are more jump in feet first to 20g...a level where most everyone becomes a fat-burner after the glycogen stores are used up. Here is a good beginners guide to the Keto Diet (which is what a 20g Atkins Diet is) https://www.dietdoctor.com/low-carb/keto with tips on handling side effects, recipes, etc.

I used the Duke Lifestyle clinic Diet which distilled the Atkins clinic plan down to very simple rules. Eat from the food list and measure a few limited foods, and you will be at 20g. No need to track "macros". https://www.dietdoctor.com/se/wp-co...starch_diet.pdf
On the list of permitted foods beef was the most filling for me. Make a fatty chuck roast in a slow cooker. Or burgers, try them topped with an egg. "Meatzza" skillet pizza...cover bottom of skillet with ground beef, flip, put on some tomato sauce, veggies, olives, sausage, a little cheese, cover pan until all cooked through. Crackslaw! https://m.youtube.com/watch?v=u8Ms3AHVoM8 Bake chicken with the skin on. Have hard boiled eggs always available if still hungry. If it is on the list, you can eat it until you are full. You do have to be careful with processed meats and check labels for added sugar, corn syrup, dextrose. Italian sausage at one store has 6g carbs, at another store none. Is there a real butcher/farmer left in your town who makes sausage without sugar or corn syrup? Sugar free sausage is hard to find, can be ordered on-line or some people make their own.

You can eat until you are full, add fats if your protein is lean, don’t count calories, but do cut out all sugar and starch.
All the best,
