Just one example of how the problem has been oversimplified is in identifying "big food" as the enemy, just like big tobacco before.
Marketers of food are soundly critiqued for creating large, super-sized portions.
However, in a nod to the wicked nature of the problem, marketers are also critiqued for offering smaller portions.
And rather more ironically, marketers are also criticised for promoting slim, "overly-idealised" body-forms.
The media, public health and popular views all share the view that obesity is a problem, but the real nature of the problem is more complex than many seem to realise.
