By Sharon Bernstein SACRAMENTO, Calif. (Reuters) - Fashion models who want to work in California would need a doctor to attest that they are of healthy weight and not suffering from an eating disorder under a proposal announced by a state lawmaker on Monday. The bill proposed by California state Assembly member Marc Levine follows efforts in several countries to fight anorexia nervosa and other eating disorders among models, who are relentlessly pressured to lose weight or lose work. "The evidence of eating disorders in the modeling industry is alarming," Levine, a Democrat who represents the Marin County suburbs of San Francisco, said in a statement on Monday.
