Remember the more you exercise the hungrier you are, its the bummer of trying to lose weight by running. I have such a short commute that I eat whatever I feel like for breakfast, this morning a bagel while I was riding in, then I have a snack at about 9:00, lunch at 11:00 which is leftovers or frozen lean meals, then a snack when I get home after track practice at 4:00 then dinner at 7:00. I run in the morning right when I get up, I try not to eat too much before I ride as it makes me sick.
