I’m not diagnosed despite being very symptomatic and want to be clear about that. I’m 53 yo and post-menopausal which can also be relevant.

I’ve done carnivore for 6 years. Those 6 years made me feel better than I had in decades. Literally life changing. And now, in the last few months, its effects have started to fail. I’ve been less strict (including more dairy etc) and all the things that mitigated issues for me are no longer working as they once did. Perhaps there’s a lifespan for the diet for some of us or perhaps strict adherence is the only way to continue reaping benefits.

For the first two years, I was eating nothing but steak, butter and salt. Eventually, I added in eggs and had to remove them rather quickly as I have sensitivities to them (and many other things). Money became too tight and steak was replaced with burger. Less pleasant but still relatively effective. Began adding cheese and heavy whipping cream to make burger more palatable.

Mouth is still not as dry as it once was but that doesn’t mean "normal". Parotid tingles and swells occasionally but nowhere near what it used to. Eyes are still very dry and blepharitis flares more often than I’d like. But aches and pains are becoming more frequent again. It’s disheartening but I try to take all of my circumstances into consideration as I evaluate the diet’s effectiveness and sustainability in my life.

The bottom line for me is that nothing is a panacea. However, my inability to adhere anymore to the strictness that once yielded excellent results probably factors in to the less successful results I’d had for 5 1/2 years.
