Not the parent commenter, but as someone who skips breakfast, it's actually not that difficult, particularly if you drink coffee (which IIRC has recognized appetite-suppressing properties). Just drink it black, and be sure to drink water as well. (Tea might be an option too, but especially in black teas, the tannins in it may make your stomach queasy absent some milk or carbohydrates -- which would defeat the purpose of skipping breakfast.)
