Fiber maxing—Is it good for your gut?
August 19, 2026 • Season 4: Episode 32
Speaking of Women's Health Podcast host Dr. Holly Thacker talks about how your microbiome connects to metabolism, blood sugar stability, satiety, and long-term disease risk. That context matters when you hear the viral phrase “fiber maxing.” Done right, increasing dietary fiber can support steadier energy, healthier cholesterol patterns, improved regularity, and better weight management, especially when your carbohydrates come from whole foods with a lower glycemic impact.
Dr. Thacker then discusses the most common infectious diarrhea causes that she sees and teaches on, including viruses that impair fluid absorption, bacteria that can trigger toxin-driven fluid loss, and parasites that often hide behind the label “stomach bug.” She gets specific about Cryptosporidium, Cyclospora, and Giardia: how they spread, what symptoms tend to stand out, why hydration is non-negotiable, and how contaminated water and produce can be the real source of the problem.
She also shares practical, food-first ways to increase fiber without bloating: build meals around legumes, add chia or ground flaxseed, swap refined grains for whole grains, keep the skins on potatoes, and rinse, rinse, rinse your fruits and vegetables. She covers how fast to increase fiber (slowly), why you must hydrate, how to balance soluble and insoluble fiber, and when personalization matters.
