For my 10 days of a Water Fast I lost about 7 kg (14 lbs?).

Ps: be on just fruits and vegies at least one day before ur start ur fast and, believe me, it will be much easier for u to get through first 2-3 days. I have done it and it was very easy for me to fast all 10 days! I was even surprised.
Just believe in urself. EVERYTHING is possible! ;):))
