My husband (who has CFS) has become preoccupied with this bit of news: https://news.usc.edu/63669/fasting-triggers-stem-cell-regeneration-of-damaged-old-immune-system/ And wants to try it for his CFS. It seems like fasting would be a bad idea for a person with CFS. At the same time, I'm not an expert. Would anyone have thoughts on this at alll? Apologies for such a random post.
