Thanks Janclebro. I was on a ketoish low-starch diet for about 7 years (with many cheats of course) leading up to my first symptom, so I wonder if I had been keeping my AS at bay for a long time. For the past week, since I got diagnosed, I've actually been on carnivore but haven't noticed any difference yet. You're the second person to recommend the keystone approach so i'll take a look.
