Absolutely. Not eating? That WILL kill you. Dry fasting can kill you, water fasting can kill you, drinking water can kill you and eating can kill you too. Anything when you take it too far will kill you of course.
Not eating or drinking causes starvation, plain and simple.Utilizing controlled starvation with dryfasting is a form of hormetic stress, which can be described as the ideal level of exposure to stressors. In other words: good stress.
Two or so weeks ago, there was a headline in the news that a priest was trying to emulate Christ’s 40 day fast. He made it 25 days of dry fasting, then died in the hospital. About a year ago, I read a story about a young woman in Russia who was found in her apartment dead after having dry fasted for too long. It definitely happens.
I hear that most people die when they go past 30 days. Generally I think 2 weeks is pretty much the safe limit from what I’ve heard. But everyone is different and your kindeys need to adjust to that sort of stress.
