I was wondering how long your longest Water Fast has been... I see you have only posted very recently. Fasting for 40 days on water for weight loss only is very dangerous if you do not know what you are doing, and can easily result in death.
PLEASE EVERYONE read all of Arnold Ehret's books on fasting before ever water fasting. An example, a person he heard about fasted only ten days on water and ended with the wrong food, and died!
