I don't really understand how pre-ride meals (or the lack thereof) would have anything to do with overall weight loss or gain. Isn't dietary weight loss or gain more related to total calories (and types of food) consumed throughout the entire day?
I don't generally eat before a morning ride, but that doesn't mean I'm skipping a meal. I definitely still eat breakfast, usually immediately after coming home. I mostly eat the same things that everyone else is talking about in this thread. I also don't have a weight loss goal, and my decision to ride before eating has never had anything to do with a desire to lose weight. I have always preferred to time my workouts so that I can eat immediately after them, and not before. I do this even when I ride later in the day as well.
