Brad is back. But more importantly Alex is back. And yes — the long-awaited Sader Digest Season 2 is here (still in our makeshift “studio,” but hey, we roll with it).

In this episode, Brad and Alex dive headfirst into the mysterious world of the gut microbiome, aka the trillions of tiny tenants living rent-free inside you. Think of yourself as a walking Airbnb, except instead of tourists, you’re hosting bacteria, fungi, and viruses who (surprise!) actually want you to succeed.

Here’s what you’ll hear:

Why your microbiome is like a garden — give it good food and it thrives, give it junk and it turns into a weed patch.

The surprising truth about epigenetics (spoiler: it’s less “fancy dinner party” and more “your genes get software updates based on your lifestyle”).

Why fiber is the unsung hero of gut health (yes, we talk poop). 💩

How stress, sleep, and diet all flip switches in your body that affect your long-term health.

Antioxidants explained: why “eating the rainbow” means broccoli, not Skittles (sorry, candy lovers).

Brad’s hot take: Skittles should never have swapped lime for green apple. Ever.

With plenty of laughs, bad analogies (looking at you, “walking Airbnb”), and actually useful takeaways, this episode makes gut science less intimidating — and more like a comedy set about bacteria.
