In America we say the opposite.
I read on Reddit and HN that all sorts of things I personally find very filling are objectively unfilling and "you'll be hungry 10 minutes later." The hive mind just doesn't match my experience.
A low fat salad will fill you up longer than either of those options due to the larger volume in my experience.
I have been in a situation where I accepted very light super (even though I run every day), in particular salads and invariably I have been awoken at night hungry as hell.
Real hunger is satisfied with calories (and your ability to process them) not the volume they have.
I think the article is misguided in general. Look, chicken breast is boring. Unless you plan on banning hyperpalatable foods altogether (good luck with that, Food Stalin), they are always going to be around. Protein keeps you full for longer than carbs, and is less calorie dense than fat. Sounds like exactly what Americans need. If these hyperpalatable foods shift toward a more protein heavy composition, it's probably going to be good for public health.
We don't need the "all natural" cult screwing this up.
