The Science of Fasting

Gearing up for a few longer fasts in next couple of weeks.
I haven't had any alcohol since NYE, which really makes everything with diet/fasting easier.
Been just eating between 1pm-6pm for the past week. Usually just nuts at 1pm, then fruit/veggie blend juice and a banana around 3pm and a decent dinner at 6pm. Gonna start out with a few 48 hr fasts next week and then see if I can get past my personal high of 82 hrs the week after.
The weight hasn't flown off as fast as I was hoping--since pausing drinking. This should really kick start it.
