I’m so sorry. While there’s not a strict diet per se, I myself am on a low/zero fiber diet, mainly liquid diet but I have a script for Kate Farms and Ensure nutritional shakes. I can’t handle fiber at all, really. I also eat a lot of soups, I eat mashed potatoes when I can, jello, broth, pudding, hot chocolate. Nothing with skins, nothing with seeds, no nuts. Little bites of a soft diet if you can tolerate it. If you feel an obstruction coming on, switch to a clear liquid diet (broth, jello, water, tea). You can google low fiber diet, or a soft diet
