I'm suprised you didn't poop yourself inside-out from the sf candy!!!! That would DEFINATELY get the water weight going....

The fat fast is only advised for those who are severely metabolicly resistant, and I wouldn't advise it, since your weight loss is so good. Don't give up!! I'd say try induction a bit again, and now you know those candies are a binge trigger for you, and should probably be avoided altogether, at least for the time being.
