Hi Wayne and welcome! My goodness don't you look snazzy in those photos!! Good on you for stepping up to the challenge at 17yo. You have set yourself a goal which is achievable (at a bit over 1kg per week) so that's a great start!
35kg lost. (November 2005 - October 2006)
15kg gained again (as at October 2010).
Back to the drawing board - Let's do this thing!
