I lose weight when I'm cycling regularly, but it probably isn't only the calories shed on the bike.

I'm up about 10 lbs from my "fit" weight, owing to 6 months out of the saddle from August to February. Now the weight is just beginning to go down, though my cycling tights are still embarrassingly tight. But yet, my weekly mileage is still quite low, and I don't think the difference is calorie burn.

I eat *LESS* when I'm riding. When I'm not riding I look for comfort and diversion by snacking, particularly in the evening. During the work week, I cycle in the evening, either before or after dinner, and afterwards I just don't have any interest in snacking - the cycling endorphins are plenty to keep me content. Sure, when i'm riding I eat full meals and there is road fuel to consume, but the net intake goes down.
