On today’s episode of the CLS Experience, host Craig Siegel sits down with board-certified internal medicine physician and gastroenterologist Dr. Will B to explore the science and soul of gut health. They break down the gut microbiome as a community of roughly 38 trillion microbes that influence digestion, immunity, metabolism, hormones, mood, and even brain health. Dr. B emphasizes authentic connection - to self, others, and spiritual wellbeing - as foundational to true health, and shares his own journey of burnout, weight gain, depression, and ultimate transformation through dietary change. The conversation challenges medication-first healthcare and instead champions a root-cause, lifestyle medicine approach built on nutrition, sleep, stress management, exercise, and consistency. They dive deep into fiber as the missing nutrient in 95% of American diets, the power of short-chain fatty acids, the gut–brain connection, IBS reversal, coffee as a gut-health beverage, alcohol and gut permeability, and the importance of small daily habits. This could extend your life - let's go deep.
