Gut health is everywhere — IBS, inflammation, leaky gut, food fear — yet so many of us still feel confused, bloated, exhausted, and unsure where to even begin. In this episode, Tess sits down with board-certified gastroenterologist and bestselling author Dr Will Bulsiewicz for the release of his new book Plant-Powered Plus. Together, they unpack why inflammation has become one of the biggest health issues of our time — and why the solution might be far simpler (and more hopeful) than we’ve been led to believe.
Will explains why the gut microbiome is the command centre for human health, how 70% of the immune system lives in the gut, and what’s actually happening when people say they feel “inflamed.” They dive into IBS, leaky gut (aka increased intestinal permeability), histamine intolerance, chronic fatigue, bloating, hormonal symptoms, and why so many women feel dismissed when their tests come back “normal.”
This conversation cuts through wellness noise and extremes — from restrictive diets to supplement overload — and brings things back to basics: food quality over food rules, consistency over perfection, and simple daily habits that genuinely support healing.
In the episode:
Why inflammation is so widespread in modern life The real science behind leaky gut and IBS How ultra-processed foods quietly disrupt the microbiome Why fiber helps some people — and hurts others (and how to approach it safely) The four pillars of a gut-healing diet Why fermented foods aren’t for everyone The surprising gut benefits of coffee ☕ How morning light, routine, and circadian rhythm affect digestion and energy Why healing doesn’t have to be complicated — and can begin quickly
This episode is empowering, practical, and deeply reassuring — especially if you’ve ever felt stuck in a loop of symptoms, restriction, or overwhelm. Healing is possible. And it often starts in the gut.
