You may have found your answer since, I'd still add some small points for the sake of the group mind.
I was wondering if there is anything I can do to increase sensitivity.
Just do the elimination diet.
It's a vicious or a virtuous circle, a descending or an ascending spiral. You've been/are consuming stuff that got you desensitized, and will keep you this way as long as it goes. So by stop consuming them for a while, you'll re-sensitize yourself to what you can and cannot absorb.
I completely follow the advice of meditation up by adding the usefulness of Self-Observation concerning diet. Be self-conscious of any of your (body, mental, etc.) reactions after consuming something, for you will increase your sensitivity by practicing it.
This thread's infos are senseful, the resurging key here is to go smart&slow (in opposition to quick&dirty).
if it works keep doing it, if not adjust and change the plan as needed.
I mostly agree with what you said, that everyone has to adapt the general principles to his/her own situation, except with those precise points.
Sometimes things seem to work due to habit, and it's only by breaking the habit that we discover that there was way more to it than what we previously thought, or 'believed'. That it was actually not working, but an illusion.
It's like the body is withdrawing from food a person has had their whole life! I got sick to the point I couldn't have bowel movements for days, sometimes 2 weeks which has never been an issue for me.
What you describe here resembles a lot the withdrawing effect happening with drug addiction, i.e. it wasn't an original need but the body got used to it and can't go without it anymore, even less than with genuine needs...
There's clearly a reaction going on. Now it's tricky because:
1. does your body really need gluten and dairy to function properly (which is also surprising regarding all the objective research you've read) ?
2. or is it actually addicted to these substances and will even do better once taken out ?
I reintroduced a small amount of high quality dairy and gluten/wheat back into my diet and felt much much better
It looks more to me like it was the
'all or nothing' strategy at fault here, the 'how', rather than the 'what'.
So in a way, maybe your body does need gluten and dairy to function properly, but MAYBE just for a while too.
This graduating process then appears to be the right approach to adopt ; once again, to go slowly until your body's ready to eventually cut them out completely, if such allows optimal health.
