If I go on a diet, does the speed at which I feel full change even when eating the same food? I don't feel like my stomach is shrinking.

Lately, I've been trying to eat slower than before.
As a result, I feel like I notice the feeling of being full much sooner at some point.

Not only reducing the amount of food
I'm wondering if the way we feel full can change as our eating speed or eating habits change.

I wonder if this is a different change from simply eating less.
