I think the trouble is that the first few losses are usually so good that subsequent 3lbs and the like disappoint us. However, I know myself that when I did slimming world my losses were 1-2 lbs a week IF I was lucky - usually it was lose one week, gain the next, so I never truly got anywhere with it.
Also, don't forget the inches - you may well find that on the lower weight loss weeks you drop more inches.
Keep up the good work
