Your gut has a clock — and most people are completely out of sync.
In this episode of The Exam Room Podcast, Chuck Carroll sits down with gastroenterologist and three-time bestselling author Will Bulsiewicz to explain how circadian rhythm controls gut health, inflammation, energy, and even your bowel movements.
You'll learn why mornings matter more than sleep alone, how cortisol actually helps your gut when it's timed correctly, and how light, movement, and meal timing send powerful signals to your microbiome.
Dr. B breaks down groundbreaking research showing that circadian disruption can flatten microbial diversity, weaken the gut barrier, and drive inflammation even without changes in diet.
If you wake up tired, bloated, anxious, constipated, or wired-but-exhausted, this episode explains why — and what to do about it.
🧠 In this episode:
- How circadian rhythm affects digestion, immunity, and inflammation - Why morning light is the strongest signal for gut health - How jet lag, shift work, and irregular mornings disrupt the microbiome - The ideal morning routine to support gut motility and energy - Why consistency matters more than perfection
