there is nothing wrong with losing weight fast. to tell u the truth, u feel good bout your self and u r happier when u lose weight. i do agree that there is always a little un happiness, but atleast when u lost weight u feel happier.and the reson people lose weight so fast, is because they want to look nice for whatever reason soon. i bet u that u would want to do the same thing, so i wouldn't be talking. nothing wrong with loseing it fast, as long as u do it healthy, and yes, it is posible. so don't see what is the problem losing weight fast, as long as it is healthy???????
