This week on Chattin Sh*t, we’re lacing up and logging miles with marathon runner Milly Goldsmith and specialist dietitian Nichola Ludlam-Raine to unpack what exercise really means for your gut.


We’re diving into the fibre-fuelled world of runners’ guts (yes, it gets messy), whether those neon energy gels are friend or foe, and what kind of training actually supports a healthy microbiome. Spoiler: it’s not about smashing PBs at every parkrun.


Plus, we’re pulling back the curtain on the science — should we trust nutrition studies funded by brands?

And what’s the deal with ultra-processed foods? From supermarket bread panic to the baffling health halo around "natural" snacks, we’re separatingthe evidence from the hype.


Grab your trainers and maybe a snack (with fibre, obvs) — this one’s for the gut-curious and cardio-loving alike.
