Flax-o-meal and Keto Hot cereal (apple cinnamon....yum) are good substitutes for oatmeal. They do have a lot of fiber, but in MY experience, won't cause a rush to the bathroom. They DO "bulk up" the stools, but for me, anyway just make things more normal, like before I was lc.

SF Hershey Peanut butter cups, on the other hand....lol
