chess | In which I make a predictable post about losing weight

I am fat. Now, nobody is to say 'you're not fat' or 'I'm fatter than you', because although it is true that I am not clinically obese and many people are fatter than me, I am carrying rather more than a few pounds over. I am, in fact, ten stone, which is a good half stone more than I should ever be, and it shows. I don't fit any of my jeans. I need to lose weight.

Apparently I shall lose all my excess pounds if I go for an hour's walk every day. I plan to try this, although I have no idea how it will work in term time (I'm presuming for then this means an hour more than the hour I do anyway going in and out of town, and term tends to be short on spare hours). I was vaguely planning to do an hour's swimming a week, as an 'on top of the walking I do anyway' thing, but the plans were quite vague as I'm not particularly conveniently situated for any swimming pools, driving to them seems to be missing the point a little, and I have to find the Motor Proctor on a full moon Tuesday with a following wind (half an hour from 2-2:30 one day a week, or 6-6:30 a couple of others which gives me that little missing-Hall problem) before I have permission to car around Cam anyhow. And I am confidently informed that I don't swim fast enough to lose any weight by it, even though this is because I Have No Muscles and hence am actually putting in a fair amount of effort to not move very far.

Does anyone have any Top Tips For Losing Weight? I haven't consciously decided I need to lose weight before; it's just sort of happened when it needed to. But I have been A Big Lazy Blob over the summer, having gone into it needing to shed a few pounds, and now it's getting kind of serious.
