Must be something international - I have the same problem ;)
I followed a diet about a month ago and managed to get down from 81kg to 79 kg (175lb) but it was so boring not being able to eat what you want so I abandoned the idea.
With regular dog walks of 1-2 hours a day I´ve been able to stay at that weight though even with pigging out every now and then.
Hope your rehab after hip replacement goes well. My wife will get a knee replacement next week so there´s going to be quite a bit of rehab here too for some time coming...
Hey Leif, the problem now, no matter which scale I use, is that the winter appetite and Xmas sweets are now converging to make any diet plan impossible.
Good luck to Birgit on her surgery. Best wishes for a full recovery!
