During my 60-days water-ony fast I lost about 10 pounds of the "bad" stuff.
The reason I started it is because I believe my body was finally able to get the message over to me, the "big guy" in charge, and the "big guy" decided to listen to the body. I merely cooperated with the body by helping it process out any sticky compulsions.
One day Body and I were sitting there looking at full-color explicit photos of food on a plate. It was touch and go for an hour, but the process worked and after that we could both look at photos of food and feel no compulsions whatsoever
Eating for us is now more of a societal thing and that is a bit more complicated to process out so for now we stick to twice a year fasting.
