Psilocybin for Anorexia: A Revolutionary Discovery in Overcoming Rigid Thought Patterns
What if a compound known for inducing psychedelic experiences could break the deadly grip of anorexia nervosa? Psilocybin, a compound traditionally linked to altered states of consciousness, is now being studied for its potential to transform cognitive patterns and offer new hope for those battling anorexia.
Anorexia nervosa (AN) is one of the deadliest psychiatric disorders, affecting thousands of people worldwide. Despite its high mortality rate, especially among young women, treatment options remain limited and often ineffective.
But new research suggests that psilocybin—best known for its psychedelic properties—may offer a promising avenue to combat the rigid thought patterns that contribute to anorexia.
Anorexia: The Hidden Struggle of Body Image and Cognitive Rigidity
Anorexia isn’t just about food; it’s a deeply ingrained mental health issue where patients struggle with body dysmorphia, poor self-image, and an overwhelming fear of gaining weight. It is estimated to have one of the highest mortality rates of any psychiatric condition.
People like Karen Carpenter of The Carpenters and many models who have struggled with unrealistic body goals have tragically fallen victim to it. While anorexia predominantly affects women, an alarming 10-15% of cases occur in men as well.
For many, anorexia involves rigid thinking patterns that prevent sufferers from seeing themselves or food in a healthy light, making recovery especially challenging. This cognitive inflexibility is a hallmark of the disorder, and it makes it nearly impossible for patients to view their body image from a different perspective.
Living with anorexia means facing a constant battle with one’s mind. It’s a war waged not just on the body but on self-esteem, perception, and ultimately, survival.

The Study: Psilocybin’s Potential for Treating Anorexia
A groundbreaking study led by Dr. Claire Foldi at Monash University explored how psilocybin affects anorexia-like behavior in female rats. Published in Molecular Psychiatry, this research showed that psilocybin could help improve cognitive flexibility—an essential step in treating anorexia’s rigid thought patterns.
Simply put, psilocybin may help patients rethink their perceptions of body image and food, making recovery more achievable.
Key Findings:
- Improved Body Weight Maintenance: Female rats treated with psilocybin showed better weight maintenance, a crucial indicator of its potential impact on anorexia.
- Enhanced Cognitive Flexibility: Psilocybin helped rats become more adaptable to changing reward contingencies, suggesting that it could help break rigid thought patterns seen in anorexia.
- Selective Improvement in Cognitive Functions: Psilocybin did not affect other behaviors, such as motivation or response suppression, highlighting its potential to specifically enhance cognitive flexibility.
Dr. Foldi emphasized the importance of addressing cognitive inflexibility in treating anorexia:
“Cognitive inflexibility is a defining feature of the condition, often emerging before anorexia nervosa symptoms become apparent and continuing even after weight restoration.”
The Role of Psilocybin in Treating Eating Disorders
Psilocybin has gained attention for its potential in treating a variety of psychiatric disorders, from depression to PTSD, due to its effects on the serotonin system and its ability to foster cognitive flexibility.
In the case of anorexia, psilocybin could target the rigid thinking patterns that make patients fixated on unhealthy behaviors and beliefs about their bodies.
How Psilocybin Works:
Psilocybin, a serotonergic psychedelic, works by altering the brain’s serotonin levels, which are thought to regulate mood, cognition, and behavior.
By enhancing cognitive flexibility, psilocybin may help patients with anorexia view food, body image, and self-worth from a more balanced perspective.

Clinical Trials and Real-World Applications
While the study on rats is promising, human trials have also shown encouraging results. Clinical trials have been ongoing since 2019 to assess the safety and efficacy of psilocybin in treating anorexia nervosa.
A recent pilot study reported that psilocybin improved eating disorder symptoms in some patients, though results were mixed.
What Clinical Trials Show:
- Psilocybin Improves Eating Disorder Symptoms: Some clinical trials have shown that psilocybin can reduce symptoms of eating disorders, particularly those tied to rigid thought patterns.
- Potential for Broader Treatment: Psilocybin’s transdiagnostic effects—its ability to treat multiple mental health conditions—could be a game-changer in the treatment of anorexia and other psychiatric disorders.
If these findings are confirmed in human trials, psilocybin could be integrated into therapy as part of a broader treatment strategy, alongside traditional methods such as cognitive behavioral therapy and nutritional counseling.
Psilocybin’s Role in Breaking Cognitive Rigidity
One of the most significant aspects of psilocybin’s potential is its ability to challenge and reshape the rigid thought patterns that dominate the minds of those with anorexia.
This cognitive inflexibility is thought to arise early in the development of anorexia, sometimes even before weight loss or other symptoms manifest.
Dr. Claire Foldi noted:
“Cognitive flexibility is critical in addressing the persistent thoughts that fuel anorexia nervosa. Psilocybin may offer a way to soften those thought patterns, enabling individuals to break free from the cycle.”
Additional Research: Psilocybin and Eating Disorders
Recent studies also point to psilocybin’s promise in treating eating disorders beyond anorexia. Researchers Elena Koning and Elisa Brietzke have explored psilocybin’s therapeutic benefits for treating eating disorders by targeting rigid thought patterns.
Koning highlighted the growing urgency to find new treatments as eating disorders become more prevalent, especially among the younger, social media-influenced generation.
A previous review study, Psilocybin-Assisted Psychotherapy as a Potential Treatment for Eating Disorders, outlined how psilocybin could help treat cognitive inflexibility—a major challenge in eating disorder treatment.

The Future of Psilocybin in Anorexia Treatment
While psilocybin’s use in treating anorexia nervosa is still in its early stages, the results of animal studies, as well as ongoing clinical trials, offer hope for a new, effective treatment option. If these studies continue to show success, psilocybin could become a key tool in helping patients not only recover physically but also overcome the mental barriers that contribute to anorexia.
As we wait for further research and clinical trials to confirm psilocybin’s efficacy, one thing is clear: its potential to treat eating disorders like anorexia nervosa is a breakthrough worth watching.
Conclusion: A New Path to Recovery
Psilocybin represents an exciting frontier in the treatment of anorexia nervosa, offering hope for individuals facing the mental barriers that conventional treatments often struggle to address. As research continues to unfold, the therapeutic potential of this compound becomes increasingly evident.
By promoting cognitive flexibility, psilocybin could provide a powerful tool in the fight against eating disorders—conditions that have long defied simple treatment solutions.
