Binge eating disorder (BED) is the most common eating disorder in the United States, affecting approximately 2.8% of adults at some point in their lives — more common than anorexia nervosa or bulimia nervosa. Characterized by recurrent episodes of eating large quantities of food in a discrete period, accompanied by a sense of loss of control and significant distress, BED is strongly associated with obesity, depression, anxiety, and metabolic syndrome. Despite its prevalence and health consequences, BED remains underdiagnosed and undertreated, with many patients failing to achieve adequate relief from available treatments. Transcranial magnetic stimulation is being investigated as an intervention that targets the neurobiological circuits underlying binge eating and food addiction.

Understanding Binge Eating Disorder: A Brain-Based Disorder
Research over the past two decades has established that binge eating is not simply a matter of poor willpower or emotional dysregulation — it is accompanied by measurable abnormalities in brain structure and function, particularly in circuits governing reward, impulsivity, and executive control.
The dopaminergic reward system plays a central role in BED. Neuroimaging studies consistently show that individuals with BED have altered dopamine receptor availability in the striatum (including the nucleus accumbens), similar to patterns observed in substance use disorders. When binge eaters consume highly palatable foods — those rich in sugar, fat, and salt — their reward circuits respond with greater activation than in non-binge eaters, suggesting a neurobiological basis for the excessive consumption.
The orbitofrontal cortex (OFC) — which encodes the subjective value of rewards and helps regulate eating behavior based on expected consequences — shows reduced activity and altered connectivity in BED. This dysfunction may explain why binge eaters continue to eat despite knowing the negative consequences of their behavior.
The dorsolateral prefrontal cortex (dlPFC) — responsible for executive function, impulse control, and decision-making — is often underactive in BED patients. This prefrontal impairment likely contributes to the loss of control during binge episodes: the brain’s regulatory systems fail to inhibit the compulsive drive to eat.
The insula — involved in interoceptive awareness (including hunger and satiety signals) and in craving — is hyperactive in BED, particularly in response to images of highly palatable food. This heightened insula response may drive food cravings that become irresistible in certain contexts.
Together, these findings paint a picture of BED as a disorder of reward-circuit hyperreactivity combined with prefrontal regulatory failure — a pattern strikingly similar to what is observed in substance use disorders.
How TMS Targets Binge Eating
TMS for BED typically targets the dorsolateral prefrontal cortex (dlPFC) and the orbitofrontal cortex (OFC), with the goal of:
- Enhancing prefrontal regulatory function to improve impulse control during binge episodes
- Modulating reward-circuit hyperactivity to reduce the reinforcing value of binge eating
- Reducing craving-related activity in the insula and OFC
High-frequency (excitatory) TMS to the left dlPFC is most commonly used, based on evidence from depression research suggesting that this approach enhances prefrontal executive function. The rationale is that strengthening dlPFC activity will restore top-down control over the reward-driven urge to binge.
Low-frequency (inhibitory) TMS to the right dlPFC or OFC has also been explored, targeting the right hemisphere’s role in reward and avoidance systems. Some researchers hypothesize that reducing right-sided reward processing may diminish the hedonic drive to binge.
Deep TMS using the H-coil has been proposed for BED because H-coils can reach deeper structures, but we are not aware of published controlled trials for this use.
What the Research Shows
The evidence for TMS in BED is promising but in early stages, and it comes from small trials:
A 2025 double-blind, sham-controlled trial randomized 60 women with binge eating disorder and obesity to 20 sessions of neuronavigated 10 Hz TMS over the left dlPFC or sham. The active group had fewer binge episodes than sham at the end of treatment and at 8-week follow-up. Craving fell in both groups with no significant difference between them, and BMI did not differ between groups. The authors noted the short treatment and follow-up periods and called for further research.
Earlier work has been mixed. A single-session study in people with bulimic disorders (Biological Psychiatry, 2010) reported reduced urge to eat after real versus sham stimulation, while a small multi-session sham-controlled trial in bulimia nervosa found no difference from sham. We could not identify published controlled trials of deep TMS (H-coil) for BED, so claims about its superiority should be treated as unproven.
Neuroimaging work suggests food-cue responses in reward-related regions may change with stimulation, but how TMS might work in BED is still being investigated.
TMS vs. Existing BED Treatments
The first-line treatments for BED are cognitive-behavioral therapy (CBT) and lisdexamfetamine (Vyvanse), the latter of which is FDA-approved specifically for BED. Both have demonstrated efficacy, but neither is effective for all patients:
- CBT is effective for many patients, but access to qualified therapists is limited
- Lisdexamfetamine is effective for many patients but carries risks of cardiovascular side effects, dependence, and psychiatric symptoms
- SSRIs, while sometimes used off-label, have limited evidence specifically for BED
TMS offers a non-pharmacological, non-psychotherapy alternative that directly targets the brain circuits implicated in BED. It does not interact with medications, does not carry the dependence risk of stimulants, and does not require the intensive time commitment of CBT. This makes it a potentially valuable option for patients who have not responded to or cannot tolerate existing treatments.
A Promising but Emerging Field
It is important to note that TMS for BED is not yet FDA-cleared for this indication. The evidence base still consists of relatively small trials, and definitive clinical guidelines have not been established.
Nevertheless, early trial results make BED an area of active TMS research.
For patients struggling with binge eating disorder who have found existing treatments insufficient, TMS — available off-label from experienced neuromodulation practitioners — is an investigational option, and patients should weigh the limited evidence.
Frequently Asked Questions
Is TMS FDA-cleared for binge eating disorder?
No. TMS for binge eating disorder is not FDA-cleared and remains an investigational treatment. Early research is promising: a 2025 sham-controlled trial of 59 women with BED and obesity found fewer binge episodes with active TMS than sham, but trials are small and larger studies are needed.
What brain target is used for TMS in binge eating disorder?
The [dorsolateral prefrontal cortex (DLPFC)](/blog/understanding-tms-motor-threshold/) is the primary target, using high-frequency excitatory stimulation. Deep TMS using H-coils has also been studied specifically for BED, because H-coils can reach deeper structures including the orbitofrontal cortex and insula.
How does TMS help reduce binge eating?
TMS may enhance prefrontal regulatory function to improve impulse control, modulate reward-circuit hyperactivity to reduce the reinforcing value of binge eating, and reduce craving-related activity in the insula and orbitofrontal cortex.
