Host Dave Asprey sits down with Chloe Melas, NBC journalist and author of The Girl’s Guide to Guts, to explore what your poop reveals about your health, gut microbiome diversity, chronic inflammation, digestive disorders, colon cancer warning signs, and the connection between gut bacteria and longevity. Chloe shares her 15-year experience with ulcerative colitis, chronic constipation, repeated antibiotic treatments, and the challenges of living with an invisible illness. She explains how dietary fiber, particularly psyllium husk, helped improve her digestive symptoms and why tracking bowel movements can provide important clues about overall health. Dave and Chloe examine the differences between IBS, IBD, Crohn’s disease, and ulcerative colitis, along with the importance of recognizing blood in stool, persistent bowel changes, and other potential colorectal cancer symptoms. They discuss stool testing, gut dysbiosis, methane-producing microorganisms, prebiotics, resistant starch, and how microbiome diversity may influence inflammation, metabolism, and biological aging. The conversation also explores hypermobility, Ehlers-Danlos syndrome, mast cell activation, mold exposure, sunlight, red light therapy, and raising health-conscious children. Finally, Dave and Chloe investigate fecal microbiota transplantation, experimental parasite therapies, personalized gut health strategies, and emerging approaches to restoring digestive function and supporting long-term health.

Host Dave Asprey sits down with Chloe Melas, NBC journalist and author of The Girl’s Guide to Guts, to explore what your poop reveals about your health, the gut microbiome, chronic inflammation, colon cancer warning signs, digestive disorders, and the connection between gut bacteria and longevity. After living with ulcerative colitis for 15 years, Chloe shares her experience navigating chronic constipation, abnormal bowel movements, repeated antibiotic treatments, and a healthcare system that often overlooked the role of nutrition, lifestyle, and gut health.
Chloe explains why your stool can serve as a daily health report card, revealing potential warning signs that deserve attention. She describes spending more than a decade without normal bowel movements, regularly checking for blood in her stool, and struggling with symptoms that many people mistakenly associate only with diarrhea. Dave and Chloe examine the differences between irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), Crohn’s disease, and ulcerative colitis, along with the importance of recognizing changes in bowel habits. They also discuss the rise of colorectal cancer in younger adults, including Chloe’s account of a woman whose rectal bleeding was initially attributed to hemorrhoids before she received a stage three colon cancer diagnosis.
The conversation explores how fiber, gut bacteria, and the microbiome influence digestive health and biological aging. Chloe describes how incorporating psyllium husk and other fibers into her routine coincided with a dramatic improvement in her symptoms and five years of remission. Dave explains how different types of dietary fiber interact with gut bacteria, why microbial diversity matters, and how stool testing can reveal information about the microorganisms living in your digestive tract. They discuss soluble fiber, prebiotics, resistant starch, polyphenols, methane-associated digestive issues, and the challenges of identifying which foods and supplements work best for an individual’s gut.
Finally, Dave and Chloe examine the future of personalized gut health, microbiome testing, and unconventional digestive therapies. They explore fecal microbiota transplantation, experimental parasite-based treatments, the potential influence of environmental exposures, and the relationship between gut health, inflammation, and the brain. Chloe reflects on the importance of advocating for yourself, asking better questions, and recognizing that persistent digestive symptoms should not simply be accepted as normal. Together, they make the case for paying closer attention to bowel habits, understanding your microbiome, and taking a more proactive approach to long-term digestive health.
