As a counterpoint to the "eat frequent meals" dogma, there is this study.

And as far as "I just realised I'm kinda asking if prolonged hunger can make one overeat lol", the answer is "Well, yes, but it's important to look at the parts of the argument and make sure they add back up to a sane real-world result".  If they didn't, then my motivational disassembly would be worthless.  A lot of science is figuring out how something works that everyone already knows to be true.

Melissa:

The problem is that while ghrelin varied sharply, actual ratings of hunger didn't.  "For the measure of hunger, these analyses produces no significant main or interaction effects as a function of shake, time or restrained eating."

So it's an interesting data point, and I'm a big ghrelin fan...but ghrelin isn't just the "make you hungry hormone".  As I said, we still don't fully understand the biochemical cascades and equilibria.

Evan:

I get the same reaction.  If I IF and don't absolutely pig out at my first meal, I can still eat more a couple hours later, as soon as some room gets cleared out in my stomach.

There's a great study in my "The Breakfast Myth" series which shows breakfast skipping is not completely compensated for by lunch and dinner calories.  So you're definitely eating a lot...but, most likely, not quite as much as you would have otherwise.

Paul:

I tend to use how I feel a couple hours later as a guide.  As I mention above, satiation can be fooled, and dessert (for me) isn't a reliable guide: I can always pack in some ice cream or cheesecake.

That being said, I've definitely had the "my stomach is bloated with food but I'm still hungry" feeling, due to not eating what my body needed at the time.

Lack of satiety affects all the other components.  I'll be discussing that very soon!

There are a lot of factors, but that's probably one of them.  Rice as a source of starch vs. wheat is another.
