The weigh-in yesterday wasn't a blip! Which means I can record the weight as official: I've reached the magic number - 10 kg lost! (That's 22 lbs to you non-metric people)
Another 2.5 kg / 5.5 lbs and I am half way - and also back at the lightest weight I have been in adult life. I don't know how realistic it is, but I'd really like to lose another 5 kg / 11 lbs before X-mas, to get down to 70 kg /154 lbs.
The low-carb thing seems to be working, so I am sticking with it for now.
