There seems to be a direct correlation between my dietary fat intake and my Ankylosing Spondylitis symptoms. Could coconut oil/ tallow / olive oil applied on skin be used to replace dietary fat intake?

@basebolt very interesting, appreciate that. Will keep an eye on it, I ordered 2kg of gelatin so Im going to try that, but might supplement with B complex then. Will keep the glycine thing in mind for when I do get problems. Thanks voor the well thought out response.

Yep, you heard that right. BCAA intolerance. Basically the only way for me to not be on meds for my autoimmune disease is to not eat any meat or dairy on a consistent basis. It never fails to flare my symptoms. Gut feels fine. Regular, solid bowel movements. Gelatin/collagen do not cause me problems. Should I just supplement with 90g gelatin daily?
I take calcium supplements as well.
Niacin, thiamine, aspirin all help for the disease, but nothing has quite moved the needle as much as cutting out BCAA rich foods.

@payreat
I also used to be chronically constipated, and now have 2-3 full formed poops daily.

Lately Ive been having 60-90 grams of protein daily from pork rinds (gelatine) and collagen powder.
I have an autoimmune disease called ankylosing spondylitis, and switching my main protein sources from meat and cheese to gelatin/collagen has nearly eliminated all symptoms to the point of being able to get off some very heavy medicine that was keeping the disease somewhat at bay.
I have much more energy now, need less sleep, and have so much less pain and stiffness in my joints. Without meds! Brain fog has cleared as well.
I have also mostly cut out starch, which doesnt make a big difference for my joints but it has almost fully cleared up my brain fog. Tongue is also clear again.
I am very grateful for all of this, but since gelatine is an incomplete protein source, I know I have to add in other sources to not become protein deficient.
Eating meat cheese eggs and milk seems to cause my disease to flare again (not immediately but very noticeable nonetheless).
I am 6'5, 90kg and have become quite muscular and athletic through the years. So far on this diet, I have lost a little bit of strength but muscle seems to have grown a little.
I would love some in depth discussion of this.
Mind you, the fact that I have been able to nearly go into full remission from a chronic, debilitating disease is a big Peat W in my book and I will try and document this process when I am fully healed.

My diet:
Coffee
2L pineapple juice
250g dates
50g pork rinds
50g honey
200g cherries
30-60g collagen
Dinner of a little starch, cooked vegetables sometimes some beef or a little goat cheese. Too much causes problems. Sometimes I eat bone broth for dinner, with white bread.

Supps:
2g aspirin daily
80mg vit K2
Sometimes I supplement zinc,magnesium,calcium
Recently started high dose thiamine (1500mg)

@BioS am familiar with the Klebsiella studies. Strangely enough, high starch low protein seems to alleviate symptoms much more than low starch high protein does

@Uroš i eat around 80 grams of protein from collagen/gelatine daily now. Do you suggest I eat 20 grams of methionine protein on top of that?

I have AS (ankylosing spondylitis) and to make a very, very long story short: after cutting out all animal protein my AS symptoms decreased severely. Could it be the cysteine or methionine? Or tryptophan?

I am looking to add in different protein sources, and am trying collagen as we speak. Because a low protein diet does make me feel very fragile and I'm losing strength in the gym.

Would love anyone else's take on this
