With so many Americans overweight or obese, public health experts are also asking this question. Since it is so difficult to follow the simple advice to "eat a healthy diet" and "exercise more," they realize that food might have addictive properties. Yet common sense demands that food — even chocolate — be placed in a different category from substances like heroin or alcohol. Addiction involves three essential components: intense craving, loss of control over the object of that craving, and continuing involvement despite bad consequences. Preliminary evidence demonstrates that people can exhibit all three elements when it comes to food. Consider the phenomenon of craving, for example. For individuals addicted to substances, environmental cues — such as a neighborhood bar or the smoking area at work — can trigger craving. Similarly, many people find that seeing or smelling food can trigger their appetite, even if they have just eaten a satisfying meal.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
