I've never felt hungry during a ride or shortly after one. At least not to the point of craving food. I do find that if all I do are short (for me) 20 mile rides that I tend to eat more at meal time and snack more in between. Perhaps to the extent of negating the Calories I burned riding.
Longer rides seem to fair much better. I supposed just the additional time involved uses up the time that while not cycling, I'd be grabbing some thing to put in my belly. Also, since I actually did burn more Calories on the longer rides of 35 to 45 miles I can eat larger portions at meal time.
DSFDF i'm sure.
