I started commuting after the Memorial Day weekend. In fact, that's when I dug the bike out. At the time I weighed 160lbs. Over the course of a couple of weeks my weight shot up to 169 and I was beginning to wonder if I should continue this biking thing. Then, as quickly as it shot up, it came back down. It now hovers around 153.
The big difference is in how much I eat. Before Memorial Day I ate like a bird. Now, I'm on a 'see food diet'. If I see food I eat it! I eat way more than I use to. I wonder if biking isn't a trap. If I get used to eating what's going to happen if I stop biking?
All the more reason to keep biking!
