Eat This Way for Better Gut Health | #1 Gut Microbiome Doctor Tim Spector

What if the reason you feel tired, hungry, or inflamed after meals has less to do with calories and more to do with the trillions of microbes living inside your gut?
In this episode of The BeingBrigid Show, Brigid sits down with Professor Tim Spector, co-founder of ZOE, the nutrition science company leading the gut health revolution.
Together they explore how emerging research is reshaping the way we think about holistic nutrition, gut health, and the connection between food and chronic disease prevention. Instead of focusing only on weight loss or blood sugar numbers, this conversation highlights a more comprehensive approach to functional nutrition and root cause healing—one that considers the powerful role the gut microbiome plays in inflammation, hormone health, energy, metabolism, and long-term disease risk.
What You’ll Learn In This Episode:
How the gut microbiome communicates with your brain, immune system, and metabolism
Why energy, mood, and hunger are early signs your gut health is improving
The surprising ways ultra-processed foods trigger inflammation
Why focusing only on calories and macronutrients misses the bigger picture
How eating 30+ different plants per week improves gut health
The difference between prebiotics, probiotics, and fermented foods
Why prebiotics may be more powerful than probiotic supplements
How gut microbes influence blood sugar spikes and metabolic health
The pros and cons of using a Continuous Glucose Monitor (CGM)
Why diversity—not restriction—is key for long-term gut and hormone health
