I tried both keto and carnivore even before the diagnosis, combined with prolonged fasting. That may have not helped actually, but hard to judge.

Now I'm not in ketosis but settled with a low-carb diet. When I feel I want carbs I have them but mostly my food is eggs, dairy (raw milk preferably, sheep and goat cheese), meat, lots of animal fat and olive oil, fermented foods (kefir, cabbage, sourcream and now i found fermented black carrot juice in a Turkish store), avocados and tomatos. But I also have some little fruits - either a banana or dried rasins, nuts etc. Occasionally a piece of good bread, or a cake but when I bake at home, I bake without flour or sugar.

I supplement but not daily, iodine in drops with selenium drops, vitamin D+K in drops. Shower in filtered water and drink filtered water with unrefined salt.I walk a lot in the sun, I'm careful about screen exposure especially in the evening.

I go to "sleep with the hen" and wake up early to catch the early sunrays.

And I do energy work with qi gong.
