Lauren Peterson began restricting her diet in her late teens when she danced with the Los Angeles Ballet. “The obsession with thinness was everywhere,” she remembers, “and like a textbook anorexic, I equated not eating with being good and being in control.” By the time she joined New York’s prestigious School of American Ballet, Peterson’s self-control had spiraled out of control, and her weight soon plummeted to 80 pounds. “I was scary skinny,” she remembers. So skinny, in fact, that even the ballet company noticed and asked her not to come back until she put on a few more pounds. She added 10 pounds to her emaciated frame and went on to dance a few more years before hanging up her pointe shoes.
