A bit rehearsed in an email now with some images and links

A phrase I have turning in my head is "It's all over until the fat lady does not sing." An stereotypically large opera diva as the statue of liberty stands on on side of a set of scales- the other scale is weighted down with books and studies and facts and tables and laws and arguments about obesity. She weighs less than these weighty tomes. The scale is made of a distorted image of the logo for The Biggest Loser.  The opera diva's mouth is sewn shut yet things are sliding in and out of her mouth at the seams.

The scale with the tomes is the hungry maw, the hungry ghost, the figure of gluttony (referencing Paul Cadmus).

Her scale is a bridle- she stands on the mouth piece, the leather straps forming a cage around her- leading to reins, some in her hand, some in the "hands" of the tomes. Some strap down the books/laws/agruments/facts/tables/studies. All of this is set on a plate, as if the viewer is a diner about to dig in.
