In fact, less than 10 percent of all those with anorexia nervosa are males. The problem typically occurs in someone with a distorted body image who desperately wants to lose weight. She may start by eliminating high-calorie foods and snacks from her diet, then progress to skipping meals altogether, or eating smaller portions. Often, a person with anorexia nervosa may eat only a few small items of food a day, such as an apple and a few carrot sticks. To burn off even more calories, many sufferers become obsessive exercisers.Unfortunately, when the body doesn't have a store of calories to use as fuel for everyday functions (such as breathing, walking, moving), It starts to burn its own muscle cells in order to come up with the calories it needs to survive.

A mental health professional trained to treat eating disorders encourages the patient to gain weight by increasing daily caloric intake by 300 calories every two weeks. The psychotherapist also tries to determine the psychosocial issues affecting the sufferer's body image, and seek to build her sense of self-worth and a more positive body image. In severe cases, bed rest with supervised meals are called for until patient has gained 10 to 20 pounds. Since the goal in treating anorexia is to encourage the individual to get better on her own, forced or tube feeding is usually avoided. In instances where the individual is clinically depressed, an anti-depressant may be given.
