I was on the AIP diet for a while, quite a long time ago. It wasn't the end-all solution for me that others proclaimed it was, but it was nice to have something new to try.
Since then I've gone on and off of strict carnivore, but anytime I reintroduce vegetables and/or some other carb sources, I'll start to see new patches of psoriasis pop back up within a 2 or 3 weeks usually. So I usually balance on that line now, returning to carnivore if my symptoms start to bother me too much.
I’ve tried all meat before and I get crazy weak. If I recall my pain level dropped a lot though. Maybe because not eating enough meat.
My wife gets crazy energetic, all her pain goes away and she’s way happier.
