And highly palatable means processed foods are easier to consume in large quantities.

So it's not just an issue of chemical composition but how we respond to these foods behaviorally.

A 7.5oz bag of potato chips is made using around 6-8 medium sized potatoes. Eating a whole bag of potato chips in one sitting is frighteningly easy to do. But I challenge anyone to eat 6-8 medium potatoes at once, despite being around the same amount of calories.

Going on a whole foods diet often results in weight loss without any increased hunger sensation.
