I find my weight does strange things during fasting.Ive lost about 60lbs now since June by doing intermittant 4 days fasts.Sometime during the fast ill lose nothing then ill eat for a few days then all of a sudden i lose 4 or 5lbs when ive been eating.I assume its just water weight,i seem to lose weight in 7lb chunks every 2 weeks.Its very,very easy to get hung up on the scales and get depressed when you dont lose anything but youve got to keep persevering with it.
