first of all, my mum works at a weight loss clinic, so i know what i'm talking about. i'm sure it really feels good to lose so much weight so fast and that's probably why you ignore everybody who tells you that it's not gonna work. our body is smart. so, when you don't eat it doesn't think you do that on purpose (who would??). so whenever you eat something, no matter if it's low fat, your body is able to produce body fat with less because it thinks that you need it really badly. this is a stragedy for surviving because in former times it really was needed. you can't stay on this diet forever, so better stop immediately and go an a healthy one.
