I think what's missing is the general awareness about the connection between excess weight and other ills: diabetes, cancer, etc., etc.
Most people believe extra weight is natural, (socially) acceptable, and just a basic modern inconvenience. It's just not wise for established leaders to say "stop drinking soda or die young."
Not to get off topic but look at Obama and healthcare. He could have tied personal health to civic duty. Instead he let the healthcare system take the blame. "You're unhealthy and you're hurting all of us" just isn't a great campaign slogan.
Of course they know. It's not a question of knowledge.
The problem is evolution designed us to eat more than we need so we don't starve in lean times - for all of human history up to, what, 150 year ago or so the biggest threat to your life was starvation. Of course if you have the willpower you can avoid eating too much. But most people don't.
