As someone who lost over 150lbs, you're full of shit.
It is my experience that absolutely nothing makes you feel fuller for longer other than filling your stomach and doing it a lot. It has nothing to do with foods being processed and everything to do with their bulk/calorie ratio.
We'll sorry, but you're argument is equally flawed... For example:
As someone who's just lost 20kg (90 -> 70kg) you're full of shit.
I primarily avoid carbs, I avoid vegetable oil, I heavily use animal fat (dripping, lard, etc) for all my cooking. I feel plenty full after my meals and stay that way until my next meal time (no snacking here, no need)..
Simple anecdote - eat a steak and egg you'll be full for quite some time, eat a big bowl of pasta (greater weight even, higher calories even) and you'll be hungry again within an hour or so (well I am anyway)..
Sure, it's one anecdote, but I've experienced this phenomenon many times throughout my life , so for me it's a 'rule' I accept (I won't say fact, as this is not science here, it's my experience only)..
