An estimated 17.3 million people worldwide have binge eating disorder (BED), making it the most common eating disorder on the planet. That figure, published in The Lancet Psychiatry based on 2019 Global Burden of Disease data, likely undercounts the true number because many people with BED never receive a diagnosis. In the United States alone, roughly 1.25% of adult women and 0.42% of adult men meet the clinical criteria.
The Most Common Eating Disorder
BED is more prevalent than anorexia nervosa and bulimia nervosa combined. Anorexia affects about 0.5% of women over their lifetime, bulimia 2 to 3%. BED, by contrast, affects an estimated 3.5% of women and 2% of men at some point in their lives. It’s also one of the few eating disorders that shows up at similar rates across racial and ethnic groups in the United States. Research published through the American Psychological Association found that BED is equally represented among African American, Asian, and Hispanic/Latino Americans, unlike anorexia and bulimia, which have historically been diagnosed more often in white women.
What Counts as Binge Eating Disorder
Everyone overeats occasionally. BED is different. A clinical diagnosis requires eating an unusually large amount of food within a roughly two-hour window while feeling a loss of control, meaning you feel unable to stop even though you want to. These episodes cause significant distress and happen at least once a week for three months or longer.
The key distinction from bulimia is what happens afterward. People with bulimia try to compensate through vomiting, laxatives, or extreme exercise. People with BED do not. That absence of compensatory behavior is part of why BED went unrecognized as a formal diagnosis until 2013 and why it still flies under the radar for many people and clinicians.
Who Develops It and When
BED can start at any age, but it commonly begins in adolescence or early adulthood. Studies using current diagnostic criteria estimate that 1% to 5% of adolescents meet the threshold for BED. Among adults seeking surgical weight loss, the prevalence jumps to around 30%, reflecting how tightly BED is linked to significant weight gain over time.
While BED is more common in women, the gender gap is narrower than for other eating disorders. Men make up a substantial share of cases, yet they’re significantly less likely to seek help. The cultural framing of eating disorders as a “female problem” contributes to underrecognition in men, both by clinicians and by the men themselves.
Rates Are Climbing
Global data tracking eating disorders from 1990 through 2021 shows that new cases of BED (along with other eating disorders) have been increasing over time. Age-standardized incidence rates are trending upward worldwide. Whether this reflects a genuine rise in the condition or better awareness and broader diagnostic criteria is debated, but the practical result is the same: more people are living with BED now than at any previously measured point.
Physical Health Consequences
BED is not simply a behavioral issue. It carries real metabolic consequences. An estimated 60% of obese individuals with BED also meet the criteria for metabolic syndrome, a cluster of conditions including high blood pressure, elevated blood sugar, and abnormal cholesterol levels that sharply increases the risk of heart disease and type 2 diabetes. That rate is notably higher than in people with obesity alone, suggesting that the pattern of binge eating itself compounds metabolic harm beyond what excess weight would cause on its own.
Most People Don’t Get Treatment
Despite being common, BED remains undertreated. A Yale School of Medicine study found that only about 49% of people with binge eating disorder sought any help at all for their symptoms. Of those who did, fewer than 30% saw a counselor or psychologist, and fewer than 20% received medication. Men and members of racial and ethnic minority groups were even less likely to reach out for support.
Several barriers explain the gap. Many people with BED feel shame about their eating and don’t recognize it as a diagnosable condition. Others assume their problem is simply a lack of willpower. Clinicians, too, sometimes miss the signs, particularly in patients who aren’t visibly underweight, since eating disorders are still stereotypically associated with thinness.
The Financial Toll
BED costs individuals and health systems substantially. An Australian population-level study found that the average annual spending per person with binge eating disorder was about $2,679 in direct and indirect costs. Lost earnings added significantly to that burden, averaging nearly $13,000 per person per year across all eating disorders. Binge eating accounted for 63% of the total personal financial cost borne by individuals with eating disorders in that study, reflecting both its high prevalence and its chronic nature.
These costs accumulate over years. Because BED often goes undiagnosed for a long time, people cycle through related medical appointments for weight management, cardiovascular screening, and mental health concerns without the underlying eating disorder being identified or addressed.
