Given a client with frequent antibiotic use and low dietary fiber, propose the best phased approach over two months to rebuild microbiome diversity and resilience. Which phased plan is most consistent with the lesson?

• A. Phase 1: Gradually reintroduce diverse fibers (root vegetables, legumes, cooked-cooled starches) to feed residual microbes; Phase 2: Add a variety of fermented foods several times weekly to introduce live strains while maintaining fiber variety; Phase 3: Emphasize long-term dietary diversity rather than high-dose single-strain supplements.
• B. Phase 1: Avoid all fermented foods and fibers to let the gut rest; Phase 2: After one month, switch to a carnivore-style diet rich in animal fats that will foster a single dominant beneficial bacterial strain; Phase 3: Maintain this with occasional processed prebiotic supplements.
• C. Phase 1: Immediately consume every known fermented food daily at maximum servings to overwhelm the microbiome with new strains; Phase 2: Stop eating fiber entirely to prevent competition; Phase 3: Continue the initial regimen until normal flora is eradicated and replaced.
• D. Phase 1: Start immediately with high-dose single-strain probiotic supplements only; Phase 2: If symptoms persist, eliminate all fiber; Phase 3: Resume antibiotics intermittently to control microbial overgrowth and then restart the same probiotic indefinitely.
