I'm not a big food person to begin with. My ability to eat really goes with my moods. My ability to enjoy food is rather limited, but I have always been this way.

For you, I'm guessing your apitite is shrinking due to extra exercise. Also your body is probably getting more endorphins from all that bike riding. I don't know much about your diet but as long as your getting enough carbs for the energy to ride, and protein, then you should be okay. I bet your appitite will return on its own.
