Author: Erin Holt September 30, 2025 Duration: 32:41

Move over, protein. There’s a new wellness obsession in town and her name is FIBER.

In this episode, Erin talks about the rising trend of “fibermaxxing” and why it’s more than just a catchy Gen Z trend. You’ll learn how fiber fuels your gut microbiome, supports short-chain fatty acid production, and impacts everything from hormone balance to inflammation.

But it’s not as simple as loading up overnight. Erin explains the distinct differences between soluble, insoluble, and resistant starch fibers, why variety is key for a resilient, diverse microbiome, and how to add fiber-rich foods and functional fiber supplements without triggering digestive distress.

Start slow, stay consistent, and prepare to reap the benefits!

In this episode:

  • Why “fibermaxxing” is more than just a TikTok trend, and how to use it to actually improve gut health
  • The hidden ways your gut microbiome shapes immunity, mood, hormone balance, and even your detox capacity
  • How different types of fiber, like soluble, insoluble, and resistant starch, work alongside polyphenols to feed good bacteria
  • Erin’s favorite strategies for upping your fiber game without the gas, bloating, or IBS flare-ups
  • Why eating 30-40 different plants each week is the simplest path to a stronger microbiome
