Shark, did you go back in time to the '70s? Sports nutrition has evolved since then, fasting is not the way to go. Unless you've been getting proteins every 3/4 hours, by fasting you only lost muscle, especially if you also excercised. Moreover, a few pounds on the scale could easily be due to water retention, constipation, inflammation (attracts liquids), carbs (1/3 carbs to water ratio), and so on. Briefly, you could have done this for nothing good at all. No wonder psyche is low.

seems unlikely that there would be loss of well used (ie useful) muscle in say a 19 hour fast.
