tapanga, don't be worried.
If you have stuck to the eating plan you will lose weight.
Everyone loses at different rates but it does come off.
I have been a member of SW a few times (my 6th now!) and the most I have lost is 4 pounds the first week, which is what I achieved this time. Last week I stayed the same but realise why, as I indulged too much in grapes and bananas.
This week will be better.
It's better to lose steadily, and keep it off.
The pounds do add up and soon you will see and feel the difference.
Good luck!
