In this podcast episode, Dr. Mark Hyman introduces "FLC syndrome," or Feel Like Crappy syndrome, a term he created to describe common symptoms like fatigue, joint pain, and digestive issues that many experience but consider normal. He points to chronic low-level inflammation, largely driven by diet, as the underlying cause. Dr. Hyman highlights how our food choices significantly affect gene expression and mitochondrial health. He recommends a 10-day detox diet that eliminates inflammatory foods—such as ultra-processed items, sugar, gluten, and dairy—while promoting nutrient-rich whole foods to help reset the body and ease symptoms. The episode reveals the remarkable potential for noticeable improvements in various health markers just days after making these dietary changes.
