In this episode of the Fit Father Project Podcast, Dr. Anthony sits down with Kiran Krishnan, microbiologist and Chief Product Formulator at Just Thrive, for one of the most eye-opening conversations on gut health we've ever recorded.
Kiran breaks down why chronic issues — anxiety, weight gain, brain fog, low energy — are often ecological problems in your gut, not genetic ones.
You have 22,000 genes, but you're carrying around 2.5 million microbial genes on top of that. As Kiran puts it, "you're not really an organism at all — you're a walking, talking rainforest."
Dr. Anthony and Kiran dig into why the modern gut is in such rough shape (hint: it's not just food), why the word "probiotic" is nearly as useless as the word "food" without specifics, and why a single gene can be the difference between a probiotic strain that changes your brain chemistry and one that does absolutely nothing.
They also cover spore-based probiotics, digestive bitters, and why both may matter more for your health than any supplement stack you're currently running.
If you've been doing everything right — training hard, eating clean, sleeping well — but still feel off, this episode will show you why the answer might start in your gut.
