About this episode

Dr. Rachele Pojednic discusses various health trends and provides her honest opinions on their effectiveness.

In this bonus episode, we’re back with Dr. Rachele Pojednic for one of our favorite games: Overrated vs. Underrated — wellness edition. Rachele gives brutally honest takes on cold plunges, wearables like Oura and Whoop, continuous glucose monitors, greens powders, zone 2 training, and IV drips. You’ll hear what she thinks is genuinely useful, what’s wildly overhyped, and what the science still doesn’t know yet. (Yes, she straight-up says cold plunges are overrated and greens powders are a hard no.) If you love hot takes and you want to stop wasting money on wellness nonsense, you’re going to love this one.
