If it works for you, sure. Interesting, I often eat a big but healthy breakfast and then eat nothing for the rest of the day, and that works really well for me.
A better general rule, I think, is that people should only eat when they're actually hungry. That could be in the morning or any time. I have an empty stomach in the morning(waking up around 6pm), but I don't usually feel hunger until between 10:30a and 12pm.
Even better, people should avoid the usual breakfast foods that are high in sugar and low in beneficial fats. I would only discourage people from eating breakfast if they're going to regularly eat foods that spike insulin and not exercise enough to compensate, in which case I believe they're setting themselves up for failure in the long term. A healthy breakfast, on the other hand, isn't harmful by any stretch of the imagination.
The easiest way to retrain yourself is to stick to simple rules about when to eat (and what to eat).
