Food Addiction

No

I watch a lot (probably too many) shows/documentaries about super morbidly obese people and in almost all of them food addiction is brought up. I'm not a doctor, I've never felt addicted to anything, and while I've struggled with my weight I've never been anything but just overweight; so my question is what do you all think about it? Is there such a thing as food addiction or is it just a lack of willpower? A lot of you ladies are much more educated than I am so I'd like to hear your opinions.
