Please don't be disappointed with 5lb loss,it is very good. I remember reading in the Lighterlife magazine of a woman that did spactacularly well over several months, reached her goal and had been maintaining for a long time. Yet, first week's loss was about 4 or 5 pounds which must have felt a bit disappointing as she would have been in a group with at least some members achieving a higher loss. But it really does all even out, on this diet you could lose a pound one week and seven the next - that is not anecdotal- it is what I have observed.
Well done and good luck for next week! x
