Daniella is a dancer trying to get into the New York City Ballet. She knows that it is very competitive, so she is practicing several hours a day. She also knows that ballerinas need to be very thin, so she is restricting her diet to 600 calories a day and only eats fruits and vegetables. She continues her workout and dietary routine for several months and on the day of her audition she feels
very weak. She ends up passing out during her audition and as the athletic trainer and physician are evaluating Daniella, they notice that she has several bruises and frequent muscle spasms. Why is Daniella having all of these problems? What will be an ideal response?
