Fast-food eaters underestimate calories
PITTSBURGH, Pennsylvania (AP) -- Next time you go out for that big burger, bucket of fries and super-sized soda, you better bring along your calculator just to be safe.

Most people, no matter how large or small they are, tend to underestimate how many calories are in fast-food meals -- a big problem as portion sizes have ballooned, a new study has found.
People make more accurate guesses when determining the calories in smaller meals, according to the results of the study published this week in the Annals of Internal Medicine.

Reading the book, "Fast Food Nation" really put me off fast food. Even beloved Taco Bell. I would say this book is the written version of the movie, "Supersize Me" only different in the sense that it is backed up by more facts and less 'propaganda-like' than the movie.
