For me, the two that are so easy/obvious to me now that I've structured my diet dilligently... acne and joint pain/inflammation. Besides getting to a healthy weight, the number one thing that keeps my back from hurting is avoiding gluten (or I should be more accurate, products that contain gluten). And to the GP, I spent years losing weight, getting a proper consistent diet going. It's not like the weeks that I cheat and have a slice of cake that I'm gorging myself. I OMAD, calorie count, and pretty much avoid anything with added sugar or preservatives these days. And yet, yes, absolutely, when I've been off gluten for a month I can tell from small isolated doses that its not good for me. Granted, I'm not sure its actually "gluten" because "cheat" eating bread in Germany does not usually cause me the same problems as eating bread in the states. EDIT: someone in here is commenting about FODMAP. Whether here or elsewhere, you have my attention! Though the food lists I'm seeing don't super align with the symptoms I see, and I don't get IBS from it.
