I agree with you Chris, I have not seen all the videos, but I am concerned. My take is that young woman is walking a very fine line between Water Fasting and a severe eating disorder. While I just I shouldn't judge her, I am concerned. She did not look healthy or happy in the videos I saw. hopefully, the Jewish holiday will give her time to evaluate and re-evaluate her actions. At this point I think she should cycle a healthy rebuilding diet with occasional short fasts if she still has health issues to address.
I would never recommend her fasts as a suggestion for action or a role model for those new to fasting. She is taking a great risk with her health, emotional well-being, and probably her life itself.
For those who argue she is doing an "enhanced fast" there is really no such thing. Using any supplements can send the wrong message to the body, and it will not know it is time to stop and rebuild.
