After about a year going raw paleo, trying everything from primal to zero-carb without really any progress, I recently found out that the staple food I was eating was causing the problem: beef. Or more specifically, beef/bison blood.
While I have enjoyed many benefits from the diet, in terms better digestion and ketone metabolism, these were far over powered by a constant fatigue, which would only be relieved when I occasionally switched to eating lamb or cooked-paleo. It were these occasions that helped me decide to get the allergy tests done and conduct my own elimination diet experiments. I now know fairly certainly that I am allergic to beef.
In light of this revelation, the path moving forward seems clear, but I know I can probably learn something more from the community. If any of you have advice and/or possible alternative explanations, please let me know.
Currently, I plan to remove raw beef from my diet for at least several months to a year. At that point, perhaps my allergic response will have faded and my stomach acid improved to eliminate more of the bovine serum proteins.
It's just going to mean a bigger hit to my bank account.
