The first thing that comes to your mind when thinking about such food, is comfort food. You can get them easily, and they taste pretty good too. These foods are basically high in carbohydrates and sugar. On their intake, the sugar breaks down, which requires insulin to get absorbed in the blood. As the intake of these foods results in the shoot up of the sugar level, the body releases a large amount of insulin, and the blood sugar level suddenly drops lower than it is supposed to. This results in a hunger attack which signals your brain to eat.
