Just to update you all, I've no officially lost over 9 stone and I'm well pleased.
10 lbs to go to my new interim target of 14 stone 10 lbs.
Probably keep at that for now as my original target of 13 stone 2 lbs doesn't seem achievable after a body test at the gym revealed that 12 stone 7 lbs of my total body mass are muscles, water and bones.
Now combining a daily food diary, calorie watching and SW to lose those last 10 lbs asap. ;-)
