After about day 3, when all the sugar burns out of your system, you aren't really hungry anymore. Psychologically you may feel the urge to eat because you're used to doing it so often, but you don't really experience the "hunger pangs" like when you miss lunch. This is because "hunger," as most of us experience it, has more to do with your brain craving sugar than it is you being truly hungry.
