Just got the cookbook version of “Going Rogue” (a title about which David Letterman was right: sounds like she’s wearing no underwear). A skinny starlet has “written” her primer on “feeling great, losing weight and saving the planet.” All by turning vegan after flying to the Amazon. Her collaborator’s name is buried in the back, but maybe that was by request given the chapter titles involving “Nasty Food.” Way to sell! No wonder the cover shot, like the Palin original, looks like a feminine hygiene ad.
