high fat low carb foods tend to be much more satisfying per calorie than foods heavy in carbohydrates

I think it depends on the person. A meal without enough carbs just doesn't feel ‘complete’ to me, and it'd take lots of willpower for me to not eat anything else for a while (but I'm mostly thinking about stuff like pasta or rice or potatoes or bread or fruits, rather than muffins); OTOH I can go several days without much proteins before starting to crave for them. And eating ten strips of bacon without anything else in one sitting would feel very distasteful to me. But I know there are people for whom it's the other way round.
