Final answer:
Jordan likely suffers from bulimia nervosa, indicated by her pattern of binge eating followed by purging. She could still have a healthy BMI, making the disorder less noticeable to others, despite its severe health consequences.
Step-by-step explanation:
Given the information that Jordan has been eating large amounts of high-calorie foods and cannot control her eating habits, followed by purging through vomiting or using laxatives, the most accurate guess about her condition is that she may be experiencing bulimia nervosa. This disorder is characterized by recurrent binges followed by compensatory behaviors such as vomiting or laxative use to prevent weight gain. Individuals with bulimia nervosa can maintain a normal weight, which might make the disorder less visible to others, potentially leading to compliments about one's appearance despite the underlying health issues.
