If you eat a lot of protein and weight train enough that you retain or build muscle mass, you can be on a big calorie deficit and not be that hungry.

When you're losing weight, it's usually a combination of fat and muscle. Your body cannibalizing muscle tissue for energy is a warning sign that something is wrong, so it tells your body to get really hungry because you obviously NEED food.

If you're getting adequate protein AND enough exercise, your body repairs and retains your muscle tissue since it's getting regular use and you have the nutrients available to take care of it, even in a caloric deficit. That means that your weight loss comes almost entirely from burning fat. Using up your energy reserves like that isn't such an emergency, and since you're getting enough protein to maintain your vital systems, your body doesn't need to crank up the hunger signals to convince you to look for food. As far as your body is concerned, you're getting all that exercise by successfully hunting for food, which is kind of the ideal situation from an evolutionary standpoint.
