You'll probably find that once it's finished, within the following week you will loose 1-2kgs. That's been happening to me in the last couple of months so I've just put it down to water weight. Also, I think because we are smaller and paying more attention to the weight loss on a daily basis, (well I am anyway) it's more noticeable than before. Hopefully you will find yourself loosing again in the next couple of weeks.
