Hi Pspondylitis,

I think the reason the diet worked is the absence of something that is part of the mechanism / root of the inflammation, rather than being an abundance of meat / protein helping out. I used to eat a fairly high protein diet normally anyway, especially when I used to work out a lot in my early twenties, and this didn't seem to help at all.

If I had to make a guess, I would guess that the inflammation is part of an immune response to a bacteria that eats sugar / starch / glucose, and eating none of those for 3 months is enough to kill off the population of the bacteria. People seem to have some success with the no-starch diet here, the carnivore diet is just a very extreme version of that.

I am now 3 months into the diet again and will start working out / exercising in the next few weeks to see if it causes me flareups. I'll report back here.
