I know it's very tempting to blame everything to our "1st world bad living", but please do not spread misinformation like this about autoimmune diseases. I am 27, always ate healthy and was very active, yet I started developing ankylosing spondylytis 3 years ago, a very painful AI disease which attacks your articulations.

And you know what ? We know that many Pharaohs of ancient Egypt had it too, including Ramses II : https://www.ncbi.nlm.nih.gov/pubmed/12548434

So long for the 1st-world, industrialized society as the root of all evils...

Moreover, sounds like your friend was on biologics. Sure, losing 75pds will help lowering the inflammation and pressure on articulations anyway. But there's NO evidence it's not just a pause in flares, sorry for your friend. I met many people with AI diseases and to date have met no one who can prove he "healed" with a change in diet. Happy to discuss about it in PM if some read that comment !

A recent study indicates clinical evidence for remission through diet in IBD:

"Clinical remission was achieved by week 6 by 11/15 (73%) of study participants, and all 11 maintained clinical remission during the maintenance phase of the study."

That's really great, but I did that protocol strictly for 3 years straight and it never worked for me. (I continued it because it had a good effect on my sinuses, but not my lymphocytic colitis).
