In this solo episode of The Proof, I dive into one of the most important and misunderstood areas of health: your gut microbiome.
From how your gut influences your immune system, brain, and metabolism, to the everyday habits that either nourish or harm it, this episode is packed with practical insights to help you build a healthier, more resilient microbiome.
I unpack the three best things you can do to support your gut and the three biggest mistakes you’ll want to avoid. I also share my personal strategy for rebuilding gut health after taking antibiotics, explain why probiotics aren’t always the answer, and bust a few of the most common myths about gut health and “resets.”
Specifically, I cover:
- How plant diversity fuels a thriving microbiome
- The power of fermented foods and how to choose the right ones
- The impact of exercise, sleep, and stress on your gut
- Why overusing antibiotics and living too clean can backfire
- How ultra-processed foods disrupt microbial balance
- The connection between saturated fat, fibre, and gut inflammation
- A simple framework to track improvements in your gut health over time
If you’ve ever wondered how to improve your digestion, strengthen your immune system, or support your brain health naturally, this episode will give you a clear, evidence-based roadmap, without the gimmicks or detox fads.
