Verified step by step guidance

1. Step 1: Understand the diagnostic criteria for bulimia nervosa according to the DSM-5, which includes recurrent episodes of binge eating followed by compensatory behaviors (e.g., vomiting, excessive exercise).
2. Step 2: Recognize that maintaining a normal or above-normal body weight is common in bulimia nervosa, distinguishing it from anorexia nervosa where weight is typically below normal.
3. Step 3: Identify that preoccupation with body weight and shape is a core psychological feature of bulimia nervosa, influencing the individual's behavior and self-evaluation.
4. Step 4: Evaluate the option 'Preference for spicy foods' and consider whether it is related to the diagnostic criteria or clinical features of bulimia nervosa.
5. Step 5: Conclude that 'Preference for spicy foods' is not a recognized characteristic or diagnostic criterion for bulimia nervosa, making it the least significant characteristic among the options.
