Bohemian, a pound a week is about right. Some weeks 2 lbs go and some weeks nothing. I used to think that all the weight gone had gone for ever and as long as I was moving in the right direction it was OK, no matter how slowly. It took about a year to lose 3st, using that alternate day method. Another 9 mths on, I have maintained the loss. This because I now eat in a completely different way, more healthily.
This does not mean that I cut anything out, but eat what I chose, in moderation. Good luck with your progress. X
