bjcole,
In general, it's better to have your meals spread out as evenly as possible throughout the day. If you eat your evening meal at about 6 pm and don't eat again until 12 noon the following day, that's roughly 18 hours between meals. During that long span of time, you have to wonder if you're burning fat for energy or lean muscle. I tend to think if it had been working, to burn fat, you wouldn't need to be on a diet.
However, if you're making good progress on your diet and you feel well, perhaps it's okay for you to do this. It's not unheard of; some people CAN do it. The main thing is that you get all the necessary nutrients that you need to maintain good health. You don't want to skip a healthy breakfast in order to eat a 300 calorie processed dessert after your evening meal. That would be very unwise and counterproductive.
Good luck!
