After I had a heart scan, the doc said the best diet is the hunter and gatherer diet - sounds like what you are doing. Atkins with extras.
This diet seems sensible. It’s pretty much hunter-gatherer.

The proponent advocates cutting out all refined sugar and flour. She doesn’t even recommend whole grain bread - just sprouted grain and rice bread. You can use Stevia, honey and other natural sugars in moderation. But no artificial sweeteners.
One recommendation is using coconut oil for frying at high temps. Never tried that and the diet nazis had such a cow over that, the movie theaters stopped popping corn in it. Have to get some.
There is a book for about $50 which I haven’t purchased yet, but may down the road. Although I kind of have the idea just from the video and info at the website.
