Fad diets no longer worked for me. My nutritionist taught me that balancing my food and portion control will not only help me lose weight, but is the key for a healthy life.

What are the main types of eating disorders?

The two most serious eating disorders are anorexia nervosa (anorexia) and bulimia nervosa (bulimia).

What is binge eating disorder?

People with binge eating disorder have episodes of binge eating in which they consume extreme quantities of food within short periods of time, and feel out of control while they are bingeing.

What causes an eating disorder?

There is no single cause of an eating disorder. Eating disorders, like several other psychiatric conditions, often cluster in families, and we now recognize that genetic vulnerability plays a significant role in risk for developing an eating disorder.
