I was making reasonable progress on losing weight (or so I thought), despite the after-effects of a dislocated shoulder limiting some activities. However, I was noticing that my clothes were inexplicably not getting looser. Yesterday morning, my posh scales reported - Oh Joy! - a 6kg loss since the previous weight check not a week earlier. Even I could see that this was an unlikely result, so I checked using my reserve, very cheap, scales. They suggested that, far from losing weight, I'd put on around 4kg since February - in other words, about 10kg more than the posh scales reported. Being somewhat sceptical, I spent this month's disposable income on a new version of my posh scales, which arrived this afternoon. A three-way comparison had the new posh scales and the cheap rubbish scales within 0.1kg of each other, and the old posh scales reading 9.4kg less. Bugger.
