Researchers have successfully altered feeding and anxiety-like behaviors linked to anorexia in mice by targeting the MC3R receptor. The study suggests that fine-tuning the receptor's activity could help change feeding habits and promote weight gain in patients with eating disorders, offering a potential new treatment for anorexia.
New research published in JNeurosci suggests that stress alters brain activity in self-inhibition areas but doesn't trigger binge-eating. This challenges the long-held theory that stress impairs inhibitory control and leads to binge-eating, indicating a more complex underlying mechanism.
Women with bulimia nervosa performed worse on a task requiring self-control when stressed, but not those with anorexia nervosa. Brain activity differences were observed between the two groups when stressed, with women with bulimia showing impaired pre-emptive slowing down.
A recent study analyzing over 20,000 genomes found similarities and differences in genetic patterns among anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Researchers found that gut microbes in anorexia patients are less diverse and more abundant in 'harmful' species. Transferring fecal samples from anorexia patients to mice resulted in similar symptoms, suggesting a link between gut bacteria and anorexia symptoms. Targeting the microbiome may be a viable treatment for anorexia.
