References to cases where people starved to death are hardly proof that fasting kills. There are many guidelines to follow while fasting, and I haven't seen anyone here support reckless fasting without proper study of the subject. Nor have I seen anyone claim that fasting is safe for everyone in every circumstance.
It's good that you cleared it up that your original post was directed to "members who mention juice feasting/fasting all time", because I would never have guessed that on my own.
