In 2016 Dr. Ohsumi changed the fasting landscape when he won a Nobel prize for his work on autophagy. Autophagy is a process that helps your cells “take out the garbage”, removing damaged cells in order to generate newer, healthier cells. It’s something a healthy body does naturally, to promote healing and overall well being. So, what does autophagy have to do with fasting? Well, fasting is an effective way of triggering this magical autophagy process. Keep in mind, autophagy is different from ketosis, which is a fat burning state, while autophagy is a cellular detoxification, anti-aging and healing process. While fasting is one of the best ways to stimulate autophagy, there are a few other ways as well.
