Psilocybin Can Free You From Negative Thought Loops About Body Image

Many people swear by psilocybin mushrooms as a gateway to self-love. But new science suggests something deeper might be at play. According to a study published in the journal Psychedelics by Genomic Press, psilocybin may offer relief for those grappling with body dysmorphia by addressing the underlying mental health condition that fuels the perception of distorted self-image and, often, eating disorders.

The study, led by Columbia University researchers, suggests that psilocybin may alter brain connectivity, potentially helping to treat body dysmorphic disorder (BDD) by reducing obsessive thoughts. 

“Our findings suggest that psilocybin’s ability to enhance connectivity within the brain’s executive control and salience networks may help patients reframe obsessive thoughts and regulate emotional responses—a promising step in addressing the core of body dysmorphic disorder,” writes Dr. Xi Zhu, a researcher at Columbia University, in the study.

In an initial trial, eight adults with moderate to severe BDD who were resistant to previous traditional treatments were given 25 milligrams of psilocybin in a supportive setting with psychological support. Participants underwent MRI scans one day before and one day after dosing to track changes in brain connectivity. Their symptom levels were assessed at intervals up to 12 weeks post-treatment to gauge the long-term impact of the psilocybin session on obsessive symptoms and overall mental health. 

According to the study, psilocybin appears to rewire the brain’s functional connectivity, enhancing communication within critical networks like the executive control and salience networks. This rebalancing can help disrupt the cyclical pattern of compulsive mental loops, opening a potential pathway to deeper healing for conditions like BDD that resist traditional treatment approaches.

“Our findings indicate that the changes in brain network connectivity we observed—especially within the executive control and salience networks—could be key to reducing the obsessive thoughts that drive BDD,” said Dr. Xi Zhu. “This study provides early evidence that a single psilocybin session might facilitate lasting shifts in mental patterns for individuals unresponsive to traditional therapies.”

The results showed a marked drop in BDD symptoms by one week, a reduction that held steady for up to 12 weeks. Increased connectivity within the brain’s executive control, salience, and default mode networks seemed to predict early improvement, underscoring psilocybin’s potential to rewire deeply ingrained patterns. By week 12, however, these connectivity shifts had less predictive power, suggesting that psilocybin’s immediate effects may be more influential in treatment efficacy than its lingering neural impact.

The neurobiology of this study also further bolsters previous findings that show psilocybin improves cognitive flexibility. In this case, psilocybin is helping patients step back from obsessive thoughts about their appearance. By linking the executive control network with the salience and default mode networks, psilocybin seems to help regulate responses to emotionally loaded cues and self-focused rumination, a shift that could be crucial for easing the grip of body dysmorphia.

“The increase in connectivity between the executive control and salience networks may allow patients to modulate their reactions to negative self-perceptions,” explained Dr. Xi Zhu. “This adjustment in brain circuitry could be what enables psilocybin to ease the relentless self-scrutiny that defines body dysmorphia.”

But cognitive flexibility can help many other conditions, too, including other obsessive-compulsive manifestations. Psilocybin boosts connectivity in areas like the prefrontal cortex, helping to loosen the mental straitjacket of obsessive loops, allowing individuals to shift focus more fluidly and break the cycle of compulsive behavior. Several studies by Robin Carhart-Harris, a leading neuroscientist and psychedelic researcher, have shown that the increase in cognitive flexibility allows patients to reframe their fears and thoughts. This, in turn, could create a pathway out of the rigidity that so often characterizes OCD. 

“While our findings are preliminary, they suggest that psilocybin’s capacity to reshape brain connectivity holds significant promise for treating disorders characterized by obsessive and self-critical thought patterns,” Dr. Xi Zhu says. “These results encourage us to explore further, with the hope that psychedelics might offer a lasting therapeutic option for individuals struggling with conditions like body dysmorphia.”
