Down half a kilo on last week but I'm not reading too much into it because I suspect it's probably mostly dehydration after my running efforts yesterday...
boabacca, I'm with you on this. The idea that utility cycling can help with weight control is only really going to be useful to people who aren't already active in their daily life. If you regularly do 200km+ audaxes, it seems obvious that utility cycling isn't going to be as much use to you from an exercise point of view.
I've read lots of advice about other ways to boost your metabolism apart from exercise - some of it genuinely science-based, most of it pseudo-scientific nonsense... eg I've heard that chilli can boost metabolism by raising your heart rate. I'm completely addicted to chilli and I reckon I must have a fairly fast metabolism, so I wonder if there's something in that. Almost certainly not the answer to all your prayers, though. In general, more intense forms of exercise are going to be the best bet - might be worth doing some kind of muscle-building work, the principle being that muscle requires higher maintenance levels of energy than, ahem, non-muscle. Maybe invest in a set of dumbbells and get pumping iron?
