I would suggest you make small modifications to your diet as it is. Cut any sugar, and skip the pasta/bread/rice.
This doesn't mean you have to ditch the meal, just the meal delivery device! lol So spaghetti becomes meat sauce on broccoli, or mushrooms, or spaghetti squahs, or calliflower, or on the plate with some eggs poached in it...
Add virgin coconut oil to your pantry and start cooking things in it, in butter, ghee, bacon fat, lard etc.
As your cooking habits change, your meals will change too!
My meals are now mostly meat, with a side of veg. (Usually salad, but that is just personal preference)
Avoid processed foods, as they are usually loaded with HFCS, and other additives that you will want to avoid.
Take it slow, and enjoy the changes. I love that I am unshackled from the restraints of carbs. My meals are so much more fun, creative and delicious.
The more I see the less I know for sure.
