Final answer:
Josie likely suffers from Bulimia Nervosa, an eating disorder characterized by binging and purging behaviors. Despite maintaining normal weight, individuals with bulimia can have serious health and mental health problems.
Step-by-step explanation:
Based on the description provided, Josie is likely to be suffering from Bulimia Nervosa. This eating disorder involves a cycle of binging on large amounts of food, followed by purging to attempt to rid the body of the consumed food to prevent weight gain. The purging may take the form of inducing vomiting, misuse of laxatives or diuretics, or excessive exercise. Unlike anorexia nervosa, individuals with bulimia may maintain a normal weight, but they can still face severe health problems, such as electrolyte imbalances and heart issues.
Individuals like Josie who engage in this behavior often experience frustration with dieting and turn to binge eating, followed by feelings of guilt or shame which prompt purging. In addition to physical complications, people with bulimia also often suffer from associated mental health conditions, including anxiety and depression, which need to be addressed as part of a comprehensive treatment plan that typically includes counseling and medication.
