Eating Disorders in the Military: The Hidden Risk You Need to Know

A service member may be screened for depression, PTSD, traumatic brain injury, and suicide risk multiple times throughout their career.

But they may never be screened for an eating disorder.

This gap matters.

Eating disorders have one of the highest mortality rates of any psychiatric condition, yet they are rarely included in discussions about military behavioral health.

Emerging research suggests this oversight may be significant. Findings from the Millennium Cohort Study, one of the largest longitudinal health studies of U.S. service members, indicate that eating disorder symptoms may occur far more frequently than military healthcare records suggest. Survey-based prevalence estimates of conditions such as binge eating disorder and bulimia nervosa appear substantially higher than the number of documented diagnoses within medical systems.

In other words, the question may not be whether eating disorders occur in military populations.

The more pressing question may be how frequently they remain unidentified within systems that are not routinely screening for them.

For clinicians working with service members and veterans, understanding how military culture, trauma exposure, and performance expectations shape eating disorder presentations may support earlier identification and more effective treatment planning.

Prevalence of Eating Disorders in the Military

Although eating disorders have historically received limited attention in military mental health discussions, a growing body of research suggests that disordered eating behaviors may be more common than previously assumed.

Several studies examining active-duty service members have found that a substantial number of individuals screen positive for clinically significant eating disorder symptoms despite never receiving a formal diagnosis.

Earlier research suggested that up to one-third of military samples exhibited disordered eating behaviors, and more recent studies continue to show elevated rates of disordered eating and risk that far exceed formal diagnosis rates, underscoring a persistent gap in recognition.

Additional research suggests that up to 30% of military women and approximately 7% of military men report disordered eating behaviors.

These behaviors may include restrictive dieting, binge eating, compulsive exercise, fasting before weigh-ins, or other compensatory practices tied to body composition requirements.

Despite these findings, documented diagnosis rates within military healthcare systems remain relatively low. This discrepancy suggests that many service members experiencing clinically significant symptoms may never receive formal identification or treatment.

It is also important to consider the role of stigma, particularly among men, in shaping these numbers, which may contribute to under recognition and underreporting of eating disorder symptoms. Cultural norms around masculinity, strength, and readiness may make it less likely for male service members to recognize, report, or seek support for these concerns. As a result, prevalence rates among men may be meaningfully underestimated.

Military Culture, Weight Standards, and Disordered Eating

Military service includes structural elements that can influence eating behaviors and body image.

Service members must maintain specific body composition and fitness standards, which are monitored through routine weigh-ins and physical readiness testing. Some individuals report engaging in rapid weight loss behaviors before these assessments in order to meet required standards.

Common behaviors may include:

• restrictive dieting
• dehydration practices
• excessive exercise
• temporary fasting before weigh-ins
• self-induced vomiting
• misuse of laxatives, diuretics, or other purging behaviors
• frequent body checking or measurement (e.g., weighing, tape measurements, mirror checking)

Repeated cycles of weight loss and regain can contribute to patterns of binge eating, restriction, and compulsive exercise.

Within military environments, however, these behaviors may be framed as part of maintaining operational readiness rather than recognized as potential indicators of disordered eating.

Recent research examining body composition pressures among military personnel suggests that strict performance expectations may contribute to unhealthy weight-control behaviors in some service members.

For clinicians unfamiliar with military culture, distinguishing between performance preparation and clinically significant behaviors can be challenging.

At what point does a culturally accepted behavior begin to undermine health?

Trauma, Veterans, and Eating Disorders

Research examining eating disorders in veterans suggests a strong relationship between trauma exposure and eating pathology.

Studies have found that PTSD symptoms are associated with binge eating behaviors among Iraq and Afghanistan veterans.

Additional research within the Department of Veterans Affairs has found that military sexual trauma is associated with increased risk of eating disorders among women veterans.

Eating disorders in military populations often exist within a broader landscape of trauma, emotional dysregulation, and identity transitions associated with service or reintegration into civilian life.

For some individuals, eating disorder symptoms may function as a way to:

• manage overwhelming emotions
• regain a sense of control
• cope with trauma-related distress

Understanding these connections can support more integrated treatment planning.

Why Eating Disorders in Military Populations Are Often Missed

Even as research on eating disorders in military populations expands, many cases continue to go unrecognized in clinical settings.

Several factors may contribute to this gap.

• Military Performance Culture Military training emphasizes discipline, endurance, and physical readiness. Strict dietary control, intense exercise routines, or rapid weight loss before fitness assessments may appear consistent with performance expectations rather than indicators of clinical concern.
• Symptoms Embedded Within Other Diagnoses Many service members seeking behavioral health care present with complex clinical concerns such as PTSD, depression, substance use disorders, or chronic pain. Within these contexts, eating disorder symptoms may be overlooked or interpreted as secondary concerns.
• Screening Tools May Miss Military Presentations Traditional eating disorder screening tools were developed primarily within civilian populations. Some service members may engage in repeated cycles of weight cutting, dehydration, or extreme exercise tied to fitness testing rather than reporting traditional body image concerns. Male service members may also present with muscularity-focused body image concerns that are not always captured by standard screening tools.
• Stigma and Career Concerns Stigma surrounding mental health care remains a barrier in many military environments. Some service members worry that acknowledging eating disorder symptoms could influence career advancement, deployment eligibility, or perceptions of reliability within their units.

As a result, individuals may delay seeking care until symptoms become more severe.

Eating Disorders and Suicide Risk in Military Populations

Suicide prevention has become a central focus of military behavioral health initiatives in recent years. Research examining suicide risk among service members highlights the complex interaction between trauma exposure, mental health conditions, and stress related to military service.

Eating disorders are also associated with elevated suicide risk across populations. Research from the U.S. Department of Veterans Affairs notes that individuals experiencing eating disorders have significantly higher rates of suicidal thoughts and behaviors, particularly when symptoms occur alongside depression, trauma exposure, or substance use disorders.

Recognizing eating disorders as part of the broader behavioral health landscape may help clinicians identify risks earlier and provide more comprehensive care.

Cultural Context in Military Behavioral Health Care

Programs such as the Patriot Support Programs reflect an important evolution in military behavioral health. There is growing recognition that treatment approaches may benefit from incorporating military cultural awareness.

Within eating disorder treatment, culturally informed care may involve understanding the structural realities of military life, including fitness requirements, operational demands, and reintegration challenges.

At Reasons Eating Disorder Center, clinicians working with military-connected patients incorporate trauma-informed and weight-inclusive approaches while considering how military culture and performance expectations may shape eating disorder presentations.

Final Reflection

Eating disorders in military and veteran populations remain underrecognized—often hidden in plain sight.

Emerging research suggests these conditions are more common than diagnosis data reflects, revealing a critical gap in identification.

For clinicians, expanding screening and looking beyond traditional presentations is essential. Behaviors shaped by military culture, trauma, and performance expectations may not appear clinically concerning—but missing them delays care.

Recognizing these patterns is key to ensuring service members receive timely, effective treatment.
