I have AS, which is a klebsiella-powered autoimmune condition like Crohn's. I've followed Ebringer's zero-starch protocol (as described in Carol Sinclair's book) and understand there are a lot of veggie options that provide carbs with only trace amounts of starch. I know your goal is zero, but rather than jump into yams and sweet potatoes from dairy and meat, you may want to try adding in veggies with virtually no starch and see how you do. Kleb will always be in your system, it's about controlling the population, and my understanding is that these very small amounts of starch are OK and will not lead to overgrowth.
For the starch content of vegetables, try this:
Do you test your food with iodine? I'm sometimes very surprised at what has starch when I do.
