Yep, there was a vague acceptance of calories and poor nutritional value, but everyone kinda ignored it, I think we thought we could maybe get away with it. 

The same thing that happened with tobacco in the 1970s. Everyone kinda laughed and said "yeah I guess it'll kill me eventually" but you could tell they just didn't really believe it. 

Supersize Me was the first thing I saw that was like "no really, this *will* kill you"

Yeah, it's one thing to say "their meals are X% more calories than recommended", and another to show what that many calories do to a person.
