Models must be an unhealthy weight to keep their boss happy. A study says modeling agencies pressure models to be a size zero. If a model is not, she will not get jobs. It is the largest ever study into eating disorders among models. It was also the first study to look at the link between not eating and pressure from modeling agencies. There is now scientific proof that eating disorders are a big health problem in the modeling world.

Researchers found that 81% of models were underweight. Many led unhealthy lifestyles to stay size zero. They missed meals, used diet pills and made themselves throw up. Over half said their agency would not give them work without losing weight. The agencies are not breaking the law. Eating disorders lead to big health problems, like heart damage, weak bones, organ failure and even death. Teenagers copy the models, which makes more problems.
