I came across the following article that reports on a study from the University of Southern California which found that fasting for three days can regenerate the entire immune system: https://www.telegraph.co.uk/science...ys-can-regenerate-entire-immune-system-study/ I don't know much about the scientific mechanisms of the types of ailments dealt with on these forums, but I've seen autoimmunity come up a lot and for myself I know that I seem to be dealing with some sort of autoimmune issue based on a very high Cunningham Panel result (testing done with Dr. Kaufman). Therefore, this study really intrigues me and has made me curious about fasting. I'd be really tempted to try the three day fast (but first I need to do some more reading about fasting hah...). Do any of you have thoughts on this? Have any of you fasted for an extended period of time?
