On the other hand I keep hearing that breakfast is the most important meal of the day and that instead you should eat very light diner. If key to proper fitness (and body building) according to the original article is proper nutrition, why would you skip the most important meal? Of course, breakfast should be healthy and not a load of pancakes on top of waffles on top of sausages that is considered breakfast in many diners.

About skipping breakfast. The concept is Intermittent Fasting. Ideally if we consume less refined carbohydrates which are quick to deplete, getting energy from "slower" sources, the natural tendency would be to reduce the need for more frequent meals.

It doesn't have to be breakfast. If I'm going to skip anything, I'd rather it be dinner. That way half the time with less readily available energy, I'll be asleep, rather than thwart my cognitive abilities when they matter most, usually in the morning.

I'd like to see some evidence or more of an explanation about the skipping breakfast thing.

The accepted wisdom and fitness/nutrition and breakfast is that until your first meal of the day, your body is in sleep mode and won't start metabolizing yet.

Why not? Caffeine works more efficiently when taken in more frequent and smaller doses. Furthermore constantly taking in caffeine will suppress hunger. If you're concerned about the sugar in many drinks, you should call that out.

Water works the same as you mention about caffeine without any side effects or potential thereof: energy leveler and producer + appetite suppressant.

I'm not calling sugar out what-so-ever. I said avoid diet and low-fat anything... normally things are low fat and diet because they have a sugar substitute. Maybe you missed that? What I was calling out is stay away from artificial.

From what I hear, an apple would be a better choice than caffeine anyway if your looking for a pick-me-up.
