Fasting is one of the most powerful healing practices in human history—it’s free, requires zero equipment, and your body is literally designed for it.

In this episode, I walk you through exactly what happens in your body during a 3-day fast, from clearing out "zombie cells" to the 60% drop in aging markers.
