Does anyone deal with gastritis flare-ups from OMAD? After 7 months on OMAD, I had an endoscopy because of horrible stomach pain and indigestion, it was shown that I have gastritis. After researching a bit on the OMAD diet, it showed a lot of acid can be built up from trying to digest a large meal. In my fasting window, I drank coffee and TOPO CHICO carbonated water. I have since cut these two things out and lengthened my window a tad, but by habit now, I'm still eating in a 1 hour window. I'm working on eating slower and lengthening my window. I eat well in my window so I don't eat junk. Just wondering if others deal with this or have experience to add or advice to share.
