I did the carnivore diet and it ended up wrecking my digestive system, causing gastroparesis, fatique, extreme irritability and PMDD. It is NOT a harmless "baseline" diet that will simply reveal to you your intolerances. Imo, it can *cause* intolerances, as many will find that foods that never bothered them before suddenly cause serious reactions.
It's like saying, "I'm going to completely alter my microbiome as well as the macro/micronutrient makeup of my diet by eliminating all sources of fiber/sugar/anything but animal products. If I stick to this long enough, it will reveal to me my 'true' state so that I can identify any food intolerances that I was missing before." No, you're dramatically changing the way your body is fueling itself, affecting who knows how many systems, and clearing out whatever beneficial bacteria you had that had helped you to digest fibers (even poorly, in your case). You are also possibly becoming nutrient deficient, depending on what you're eating and how long you persist with the diet. Someone even reported developing anemia due to B1 deficiency while on carnivore. I think you're priming yourself to be more sensitive, especially if you do carnivore diet long term.
I came to this forum after listening to a video by Danny Roddy that explained why he quit the carnivore diet. It was the first time I'd heard someone who had clearly done the diet long term, to a T, and was admitting that he felt terrible on it. He was admitting that it didn't work, that it caused negative symptoms. What a breath of fresh air after being in the carnivore echo chamber in which everyone assures everyone else that the diet is at worst harmless, and at best a cure-all or the perfect human diet ... In my experience, this restrictive diet (and food elimination mentality) will cause more problems long term than it appears to be solving at first.
I don't have any advice for you wrt your issues, as I'm still trying to eat like a normal person, two years after quitting carnivore. I will say though that I'm now able to eat foods that before were causing me extreme bloating and discomfort as well as depression/anxiety. I thought I had SIBO, I thought there was something terribly wrong with me, that I needed a cure, or I needed to eliminate more damaging foods. But now ... I drink milk. I eat potatoes. Both caused serious reactions even a year ago.
Anyway, good luck. Just know that carnivore is not a miracle, not harmless, and, imo, not a solution to anything.
Awsome post animalcule. Thanks for sharing your pov.
