Office Hours: The Fiber Trend—How Much Is Too Much?

The podcast addresses the trend of "fiber maxing," or dramatically increasing fiber intake, and its effects on health. While fiber offers benefits like weight loss, blood sugar control, and microbiome support, Dr. Hyman cautions against excessive intake, especially for those with gut inflammation or irritable bowel syndrome. He emphasizes that the goal should be metabolic and gut resilience, achieved through the right types and amounts of fiber tailored to individual needs. Fiber is crucial for feeding the microbiome, regulating cholesterol, stabilizing blood sugar, and balancing hormones. Dr. Hyman advises increasing fiber intake slowly, pairing it with adequate hydration and protein, and focusing on whole food sources while avoiding ultra-processed high-fiber products.
