every kg is around 2.4 lbs, yeah you can lose that much, I have lost around 5 kgs y one week, and I wasn't fasting, just dieting and excercising twice a day
So you can lose that much, just make sure you get out of the fast properly, cuz otherwise you'll gain it all back.
I find it really easy to lose weight, for me what is difficult is to stay at that weight, cuz I always want more and more, so I fail...
Well good luck =)
your bf should find you gorgeous anyways, just the way you are, heh, well yeah he can find you better
heh, well bye =)
