Hi Sharon - 5lbs (10 blocks of butter!) is a really good weight loss, well done x
As said before me, everyone loses weight at different rates but I bet you after 4 weeks we'll have all lost around the 1 stone mark, regardless of what our weekly loses are.
By the by, you're ticker and info box to the side say "4lbs" - don't cut yourself short hun - get it changed to 5!
Best wishes for week 2, you are doing fab x
(ps - I think it's 10 blocks of butter??? 8oz to block of butter, 16oz to a Lb?!)
