EPISODE SUMMARY
If you've ever wondered what the microbiome actually is, and why every practitioner seems to be talking about it, this is the episode to start with. Karly Raven breaks down what's living in your gut, why diversity is the number that matters most, what's disrupting it for so many women, and what it actually takes to restore it.
This isn't a 30-second explainer. This is the full picture, with the clinical context, the honest caveats, and the practical starting points that most gut health content skips.
KEY TAKEAWAYS
- Your microbiome contains around 100 trillion microorganisms and their diversity directly shapes your digestion, immunity, mood, skin, hormones, and more
- Dysbiosis is driven by far more than antibiotics: chronic stress, processed food, restrictive diets, and gut infections all play a role
- Diversity is the metric that matters most. A high-diversity microbiome is more resilient, more anti-inflammatory, and better at restoring itself after disruption
- The most evidence-based way to increase diversity is to eat 30+ different plant foods per week. Variety matters more than quantity
- Restoration is not just about food. Sleep, movement, and nervous system regulation are all essential parts of rebuilding microbiome health
IN THIS EPISODE
- Part 1: What the microbiome is and why it matters
- Part 2: The most common drivers of microbiome disruption
- Part 3: Why diversity is the key metric to focus on
- Part 4: Evidence-based strategies to restore and rebuild
