I'm part way through week 5 as yet and, although the scale hasn't shifted too much, I'm starting to notice a big difference in how my clothes fit. Particularly around my ribs, bras that were once crushing my breathing are now fitting really comfortably. That does seem to be the only part of me that has shrunk as yet though except a tiny bit from my waist.
A different kind of goal: I ran today! I got up and ran! First time in 3 years! It was quite a short run, only 10 mins split up with brisk walks but its a start!
