When Eating Disorders and Trauma Overlap
The research on trauma and eating disorders is substantial and has been building for decades.
In a clinical sample of patients with eating disorders, traumatic experience prevalence exceeded 90% in inpatient and outpatient samples of individuals with anorexia nervosa and bulimia nervosa when measured with a standardized trauma assessment (Tagay et al., 2021). In residential treatment settings, nearly half presented with symptoms compatible with a PTSD diagnosis (Brewerton et al., 2020). And when formal PTSD criteria are applied across eating disorder samples, pooled lifetime prevalence estimates reach nearly 25% — a figure that likely underestimates the true burden since it captures only those who meet full diagnostic criteria (Ferrell et al., 2022, as cited in Convertino & Mendoza, 2023).
Brewerton (2023) argues that trauma and PTSD are often major drivers of eating disorder complexity and that treatment that doesn't address them is working against itself.
What this means clinically is that for many people, the eating disorder didn't develop in a vacuum. It developed in response to something. A body that felt unsafe, wrong, or out of control, and a self that absorbed the message, from abuse, neglect, chronic criticism, or loss, that it was too much, not enough, or fundamentally flawed.
The food and body behaviors made sense in that context. They offered regulation, control, numbness, or punishment in a system that didn't have better options at the time. It was an adaptation for survival.
And that adaptation is what AIP-informed EMDR targets directly.
What EMDR Is Targeting in Eating Disorder Treatment
When EMDR is used with eating disorders, the processing targets aren't the food behaviors themselves. They're the underlying material that sustains them (Morando, 2024; Hatoum & Burton, 2024).
This typically includes:
Negative beliefs about the self: The beliefs formed around early adverse experiences ("I am worthless," "I am unlovable," "my body is wrong," "I am a burden") become the lens through which everything gets filtered. EMDR's standard protocol identifies these negative cognitions explicitly and works to reprocess the memories that built them (Zaccagnino, 2016, as cited in Balbo et al., 2017).
Body shame and appearance-based distress: A
2024 study that EMDR significantly reduced body shame and appearance-based rejection sensitivity while increasing self-compassion, with effects maintained at follow-up (Pouladi et al., 2024). These findings are clinically relevant for eating disorder presentations where body-based shame is a central driver.
Traumatic memories tied to the body: Bullying about weight or appearance, sexual trauma, critical or controlling relationships with caregivers around food. These experiences often sit at the origin of the eating disorder. EMDR targets the specific memories, the emotions attached to them, and the beliefs that formed in response (Irtelli, 2025; Rossi et al., 2024).
Triggers that activate the eating disorder cycle: The AIP model understands current triggers as activations of unprocessed past material. A comment about your body, a family dinner, or a number on a scale can function as portals back to earlier experiences. Processing the original material changes the charge of the trigger (Shapiro, 2007).
Research on EMDR and Eating Disorders
The evidence base for EMDR in eating disorder treatment is growing, though still developing.
A 2024 systematic review by Hatoum and Burton, published in Mental Health Science, evaluated eight studies across presentations including anorexia nervosa, bulimia nervosa, binge eating disorder, ARFID, emotional eating, and body image disturbance. Case studies across presentations showed promising results including decreased body dissatisfaction, reduced emotional eating, and reduced food avoidance. Results from experimental studies using comparison groups were more mixed, and the authors note the evidence base is still limited by small sample sizes and the need for larger controlled trials (Hatoum & Burton, 2024).
A 2024 quasi-experimental multicenter study found that adding EMDR to enhanced CBT benefited patients with anorexia nervosa who had histories of moderate to severe childhood maltreatment, a population that often struggles in standard treatment (Rossi et al., 2024).
A 2026 pilot RCT examining EMDR specifically for binge eating disorder found significant between-groups effects favoring EMDR for eating concerns and body image distress, as well as reductions in emotional eating (Hatoum et al., 2026).A separate randomized controlled trial comparing EMDR directly to CBT for binge eating disorder in patients with trauma histories is currently underway (Castelnuovo et al., registered 2024), and will add significantly to the evidence base.
What this tells us: EMDR is not a replacement for comprehensive eating disorder care. Nutritional rehabilitation, medical monitoring, and behavioral stabilization remain foundational when indicated. But for people whose eating disorder is rooted in unprocessed trauma, and research suggests that is a significant portion of the population, EMDR addresses something that behavioral and cognitive approaches often do not reach.
Who is EMDR for Eating Disorders Suited for?
EMDR isn't the right fit for every person in every phase of eating disorder treatment. For some people, foundational stabilization work comes first before reprocessing begins. The resourcing phase of EMDR builds that capacity, but someone in an acute medical crisis or early recovery may need more time before that work is appropriate.
But EMDR deserves serious consideration when:
- Standard eating disorder treatment has helped, but something underneath still feels stuck
- There's a clear history of trauma, including childhood maltreatment, sexual trauma, relational abuse, or chronic criticism that feels connected to the eating disorder
- Body shame is persistent and doesn't shift with cognitive work alone
- The eating disorder behaviors function primarily as emotional regulation, a way to manage feelings that haven't had anywhere else to go
- You've understood your patterns intellectually, but still can't move them
If any of that is familiar, the issue may not be willpower or insight. It may be that the underlying material hasn't been processed yet.
How We Treat Eating Disorders Through EMDR at HHC
At Houston Healing Collective, we don't treat eating disorders and trauma as separate problems. We treat them as the interconnected presentations they often are.
We often offer EMDR as part of our
eating disorder treatment services. Our
EMDR therapists work with eating disorder clients through approaches that are grounded in the AIP model. In practice, this means starting with a thorough history, identifying the memories and beliefs that shaped the eating disorder, building nervous system capacity to approach that material, and processing it through EMDR's standard eight-phase protocol.
For clients whose trauma involves chronic relational patterns, early attachment wounds, or complex trauma that developed over time, we layer in IFS-informed parts work, somatic approaches, and
trauma-informed yoga to support the reprocessing work. And for clients who have worked hard in therapy and still feel stuck at the edges of what's possible, we also offer
ketamine therapy services, including ketamine-assisted EMDR, a specialized protocol that uses the neuroplasticity window ketamine opens to allow deeper reprocessing than standard EMDR alone.
The eating disorder is never the enemy. It's information. Our job is to help you understand what it's been protecting and build something that works better.
Ready to Talk?
If you’re in Houston and wondering whether EMDR might be a helpful addition to your eating disorder treatment, we’d be glad to talk. Our therapists specialize in complex trauma and eating disorders, and we’re one of the few practices in Houston offering the full integration of EMDR with ketamine-assisted therapy for eating disorders.
Serving clients in-person in Houston, Bellaire, West University, River Oaks, The Heights, and Sugar Land, and virtually across Texas.
