Well, after much consideration, I opted to get on the scales on Thursday, and (once the initial shock wore off) I am glad I did. Not only have I lost 2 lbs since, I have also come to the realisation that I need to lose 2 1/2 stone, and not 2 as I had originally guesstimated. I'm just pleased that I didn't wait and get on the scales in say a fortnight's time and think that I had not lost any weight at all.
Still feeling happy and motivated, and off to do my third run for the week. 😀
It makes it easier for the fab 5's to collect all that data and they can respond to you easier as well, as they get very busy.
