What's the actual difference between ADHD-driven impulsive eating and clinical binge eating disorder?

Binge eating disorder is a formal diagnosis requiring specific criteria. Recurrent episodes of eating unusually large amounts of food with a sense of loss of control, occurring at least once a week for three months, along with associated distress, while ADHD-driven impulsive eating can be more sporadic and situational without necessarily meeting that frequency or severity threshold. The two frequently co-occur (research shows meaningfully elevated BED rates in adults with ADHD), but not everyone with ADHD who eats impulsively meets full diagnostic criteria for BED specifically.
