Binge Eating Disorder (BED) characterized by recurring episodes of eating significantly more food in a short period of time than most people would eat under similar circumstances, with episodes marked by feelings of lack of control. This disorder is associated with marked distress and occurs, on average, at least once a week over three months (American Psychiatric Association, 2000)2

BED DiagnosisSource: NEDA

BED - Research Criteria DSM IV7Recurrent episodes of binge eating, with both of:Eating in a discrete period (e.g., 2 hours) an amount of food definitely larger than most people would eat in a similar periodA sense of lack of control over eating during the episodes

Episodes associated with three or more of the following:Eating much more rapidly than usualEating until feeling uncomfortably fullEating large amounts of food when no feeling physically hungryEating alone because of being embarrassed by how much one is eatingFeeling disgusted with oneself, depressed, or very guilty after overeating

Source: American Psychiatric Association, 2000

7Period of time: continual snacking not considered a binge; location can change (start at restaurant, finish at home)

Large amount: context important, not at a celebration where others are eating a lot as well. Requires reviewing in detail b/c perceptions of large can vary a lot. One important thing to consider is that after surgery, large amount has a very different meaning and when assessing someone who is post-op and had binges before surgery, need to highlight that large amount after surgery should be in comparison to what they are typically able to eat, not in comparison to what they ate before surgery.

Food type is often sweet, high-calorie, but amount is bigger concern than type

8Marked distress regarding binge eating is presentBinge eating occurs, on average, at least 2 days a week for 6 monthsBinge eating is not associated with regular use of inappropriate compensatory behaviors (e.g., purging, fasting, excessive exercise) and does not occur exclusively during the course of anorexia or bulimia nervosa

B. The binge-eating episodes are associated with three (or more) of the following:eating much more rapidly than normaleating until feeling uncomfortably fulleating large amounts of food when not feeling physically hungryeating alone because offeeling embarrassed by how much one is eatingfeeling disgusted with oneself, depressed, or very guilty afterwards

Obese BED showed greater blood pressure, negative affect and anxiety irrespective to stress taskStressed-induced change in hunger was associated with cardiovascular measures in obese BED onlyResults indicate that BED and obesity are distinct in terms of psychological and physiological stress-related factors21
