I like of feel like it's easy to "prove" the opposite.

If I eat a meal comprised of fat and protein (2 fried eggs with some cheese, for example), I'll feel sated and won't feel hungry again for up to 5 hours.

On the other hand, it I eat a bowl of pasta, I'll feel very full immediately after eating, but am guaranteed to feel hungry again in ~2h.

I firmly believe that fat and protein are more "filling" than than carbs, and many people have shared similar anecdotes.
