Stylist to the stars Rachel Zoe is best known for turning her clients into bobble-headed stick figures, most notably Nicole Richie, but she's also had Keira Knightly and Lindsay Lohan as clients. Zoe recently admitted that she doesn't always eat (gasp!) because she is her last priority.

She explains that, on a busy day, it can get to be 7:00 at night and she'll realize that she's only eaten a grapefruit and some coffee. Still, she claims, "It's not that I don't eat. I eat." You know, when she has the time. Which she never does.
Whether it's just due to her unhealthy eating habits (or simply lack of eating, period), Zoe's influence on Hollywood has been palpable. She denies having anything to do with the size zero craze that's taken over, but considering she and her clients are among the scrawniest in the land, it's hard to imagine the fault doesn't lie at least partly with her.
