Regarding the autoimmune aspect, I think it's too late to revert the damage done to the adrenal glands, so it's "just" a "nice to have" feature to avoid new complications. It seems to take a long time (many months) to actually observe the benefits of a gluten-free diet once you already have the auto-immune damage, so I'll reserve that for later. She's extremely skeptical of all of this line of thought (very conservative cereal girl) so I'm concentrating on the weight loss and avoiding diabetes first. After gaining her confidence with that, I'll probably be able to squeeze in the grain ban.
