You should not be working fulltime and water fasting. That is dangerous! You are not taking in any nutrition whatsoever and you will lose weight because your body will start digesting itself. I don't want to discourage you from healthy living but waterfasting while working and exercising is risky. Please be careful!

Also the more you hate your flabby thighs, the longer they will stay around :-) I understand the sentiment though. I used to hate my belly but I had to accept myself first.
