ive done it twice. the first time i did 4 days, the 2nd i did 6 days. im doing it again next month and im going the whole 10.
you notice weight loss immediately, but initially its just water weight. your energy and concentration levels are thru the roof. sure you feel hungry, but you dont feel sick at all.
you CAN go right into it without hurting yourself, but its harder to get into the groove that way. now coming off you can hurt yourself...however long you plan to do it, add 2 days to it to lead back into normal food. for example, if you do it for the recommended 10 days, you wont be eating normally again until the 13th day
the only herbal teas you should be drinking during the fast are "smooth move" and peppermint tea. if you opt to do a (sea) salt water flush in the morning, then you can eliminate the smooth move tea. table salt does not work, use sea salt. they both have the same pros, but different cons. smooth move gives you cramps and the salt water is disgusting. nothing else should be added to this fast, unless you have meds that need to be taken, you can still do meds on this fast, but talk to your doctor PLEASE
some tips:
-use grade B maple syrup, its the most nutritious and most suitable for the fast.
-if you get too hungry on this fast, add extra maple syrup to your lemonade.
-strain out the pulp! if you leave it in, your stomach will digest it and churn and growl, making you feel extremely hungry.
but dont take my word for it. here is the original text by the man who created the fast. i suggest you read it before you start the fast:
