What characterizes the eating pattern of people with bulimia nervosa?

Question

Quizplus · Accepted Answer

People with bulimia nervosa typically engage in strict dieting before a binge eating episode, which is a hallmark characteristic of the disorder. This is often followed by purging behaviors such as vomiting or laxative use to try and compensate for the binge. Binge eating can occur at any time, not just as a reward for something done well, and typically involves high-calorie and high-fat foods, not necessarily nutritious ones. Binge episodes can last longer than 20 minutes and do not necessarily involve "binge buddies."
