Foods with good fat sources tend to be high in protein, as well, which takes longer to digest and therefore you are sated for longer.

Insulin makes you hungry, and sugars make you release insulin.

That's not to say carbs are necessarily bad -- they're fine in moderation and good if you are trying to build muscle or show off, though you have to know your body and how to time those.

I still remember 90s commercials for popsicles. "high fructose corn syrup! It's good for you, because it's from corn!"

Amazing, really. Corn syrups being used in everything from beverages to foods absolutely contributed to massive diabetes rates. They're calorically dense pure and empty carbs with no nutritional value.

Only value of corn syrup is for rare dessert use or if you need to burn carbs within 30 minutes or so for a workout.
