I usually do not eat anything as soon as I wake up (have been like this for years). I tend to actually feel hungry around 11am then I will eat. My 14 year old son has breakfast every morning but on the weekends he will naturally not eat when he wakes up and will eat around noon. I think breakfast is a conditioned response in our society. I believe one should not eat unless one is truly hungry. Granted given our hectic, modern lifestyles this can be problematic. I think one important aspect of paleo (I think of it more as just a Human diet) is listening to one's body (if one is not metabolically deranged) and eating when hungry not because society says it's time to eat. Eating when one is not hungry can definitely mess with our bodies natural feedback mechanisms.
Of course a lot of people never experience true 'hunger' because if we even think we may be hungry we have easy access to a multitude of foods 24/7.
