The satiating effect of protein can be diminished by processing, refinement, and palatability, whereas whole foods like chicken breast are highly satiating.

“So now, I want to be careful because appetite effects tend to be very specific to individual foods. So you can take a high protein food and make it not very satiating. So take, for example, like a really tasty protein bar, which back when we were getting into this, no such thing existed. Now, you have protein bars that actually take pretty darn good. But if you eat one of them, I mean, are you really satiated? I don't really feel satiated, that's my protein bar.”
