The Gut Health Masterclass: Making Science Digestible With Dr. Will Bulsiewicz

from The CLS Experience with Craig Siegel · host Craig Siegel

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. 6:42 Gut Microbiome 101: Why It’s the Body’s Command Center14:53 Fiber Deficiency & Microbiome Diversity25:09 Short-Chain Fatty Acids, GLP-1 & Brain Health33:53 Dr. B’s Personal Health Transformation48:54 Coffee, Consistency & Daily Habits52:30 Alcohol, Leaky Gut & Microbial EndotoxinsCheck out Dr. WIll on Instagram HERE: Check out Dr. WIll's Website HERE:Check out Dr. Will's Book HERE:Tickets now available for our live event March 5th, CLS: Genesis HERE:Check out our brand new RISE Framework to unlock your purpose HERE.Check out our partner Belay using our custom link HERE to find the best help available to grow your business!To join our community click here.➤ To connect with Craig Siegel follow Craig on Instagram➤ Order a copy of my new book The Reinvention Formula today! ➤ Join our CLS texting community for free daily inspiration and business strategies to elevate your day, text (917) 634-3796➤ INSTAGRAM➤ FACEBOOK➤ TIKTOK➤ YOUTUBE➤ WEBSITE➤ LINKEDIN➤ X
