Does exercise make you thinner?
Meg sent me this article about studies showing that exercise doesn't really make you thinner. I like the article because it rings true for me impressionistically in addition to being well argued. Every time I have trained for a marathon, for example (which has been lots more times than I've actually gotten through the training and actually run a marathon), I've gained weight over those few months when I was training. Whether this was because I ate more because running made me hungry (or because I felt justified eating more when I was running more) or because I was gaining muscle, or some combination of the two, I don't know. But I didn't really care, because I knew I was getting in shape regardless of the number on the scale. And I also knew there were plenty of good reasons to keep up the running besides the (nonexistent) weight loss.
