It's the protein in the steak that makes you feel full so fast. Not the fat. Compare a steak with nuts, which plenty of people overeat. Nuts are much lower in protein. And blueberry pancakes are not really low-fat.
And no, I don't believe in carb addiction. Try a low-carb diet and you might think you have a carb addiction. But if you go to vegan websites, you'll hear people talking about their "meat addiction". Once I read about a raw vegan complaining about his "cooked food addiction". And when I was on a low-fat diet, all I wanted to eat was a cheese omelet dripping with butter. That was my "fat addiction". It's all the same thing to me.
