GLP-1 receptor agonists can trigger or exacerbate restrictive eating behaviors and food aversions, mimicking Avoidant/Restrictive Food Intake Disorder (ARFID), in patients with obesity and those with rare genetic disorders of obesity.

Be aware that GLP-1s can make you lose interest in food entirely. If you find yourself unable to eat enough to maintain your health, or if you develop strong aversions to specific foods, inform your doctor immediately. This may require dose reduction or discontinuation.
