Protein has as many calories as carbohydrate, and fat has even more. To feel full you have to stuff yourself with placebos like fiber instead of food.

It isn't the calories that matter. To feel full your brain needs to receive signals from your body that you should feel full. It appears that carbohydrates mess with these signals so that your brain thinks you are not yet full when you should be. You can easily try it for yourself.
