What I get out of it is, the problem with refined carbs is both how fast it gets absorbed in you gut/stomach thus spiking your blood sugar and the sheer amount you can eat. I think those two play off each other. With unprocessed vegetables generally you get a lot of bulk fiber and water along with the carbs. If your gut is full of fiber you tend to not be hungry. If it's mostly empty then you tend to be hungry.

Also one thing I've read more recently is the gut has it's own nervous system and hormonal signaling. It's high;y away of what is going on in it's world. However mostly that information isn't available to your brain. But what it can do is control your feeding behavior. If your gut is full and busing extracting nutrients, then it signals your brain to stop feeding. Ever wonder why if you eat a good meal you can got for hours without wanting to eat anything? That's why.
