About this episode

In this episode, Dr. Josh Axe explains the physiological effects of a 3-day fast and the benefits of fasting for health.

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. But while it sounds simple, there is a wrong way to do it, especially when it comes to the hormonal "engine switch" that happens in the first 24 hours. 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.
