Without healthy, well established colonies of lactobacteria in your gut, the only thing holding back uncontrolled candida growth is your diet. I have not been able to find the reproductive rate specifically for candida, but under favorable conditions bacteria populations can double every twenty minutes. What this means is that even one serious "cheat" can undo weeks and weeks of diet and antifungals.
One candida treatment plan calls for seven weeks of strict diet and antifungals before even trying to re-establish the lactobacteria. I think this plan has merit. You need seven UNINTERRUPTED weeks of diet and antifungals before you have a serious chance of re-establishing the lactobacteria colonies. Cheat? Start the seven week cycle at the beginning, all over again.
