This is a difficult question because the answer, in my opinion, can't be that it's definitley "good" or "bad". It depends on the person and the circumstances. In general, the King/Prince/pauper theory has some merit.
However, if you look at Okinawans (known to be the healthiest and longest lived people in the world), they eat every meal until they are 80% full.
Most likely they would object to "eating breakfast like a king", whatever that means (it needs to be defined). Some people might take it that it's okay to stuff yourself or indulge in high calorie foods.
Anyway, I'm in favor of eating every meal with a little restraint; I try to feel satisfied without feeling full.
