GLP-1-mediated caloric deficit may trigger starvation-response restriction through neurobiological misinterpretation of pharmacological appetite suppression as famine

Multiple clinicians quoted in NBC News describe a progression pattern: beneficial appetite suppression → pathological restriction → 'atypical anorexia nervosa' presentation. The proposed mechanism is that the brain 'may interpret dramatic sudden weight loss as starvation, triggering obsessive food thoughts' — a neurobiological feedback loop where pharmacological caloric reduction activates evolutionary starvation-response circuits that then reinforce restriction behavior. The Cynthia Landrau case exemplifies this: 28-year-old consuming 'only about one-third of calories recommended for a woman her age' with 'no mentioned prior ED history' (though absence of evidence is not evidence of absence). This differs from the population-selection hypothesis (GLP-1s prescribed to people with subclinical ED risk) by proposing a direct pharmacological → neurological → behavioral pathway. Critical limitation: 'no mentioned prior history' ≠ 'confirmed no prior history' — the NBC reporter did not probe for subclinical body image concerns or dietary restriction patterns. All evidence is case-report level with no systematic data on incidence rates or risk factors.
