Can detox teas, juice cleanses, and parasite cleanses actually flush toxins out of your body or is the wellness industry overselling the science? In this episode of Health vs Hype, Trace sits down with gastroenterologist Dr. David Purow to unpack one of the biggest wellness trends online: detoxing.

VO2 Max is everywhere, from fitness trackers and smartwatches to social media and even dating profiles. But what does this number actually mean for your health? In this episode of Health vs. Hype, we break down the science behind VO2 Max (maximal oxygen consumption) and whether it truly deserves its status as the ultimate fitness and longevity metric.
