A new study has found that blood sugar and insulin resistance may play a role in alcohol cravings, particularly for people with both alcohol use disorder (AUD) and obesity. The study compared data from 31 individuals with AUD to 41 healthy controls, who also had obesity. It found that higher glucose levels and greater insulin resistance were directly associated with stronger cravings triggered by stress and alcohol cues. The findings suggest that those with both AUD and obesity may have metabolic alterations that contribute to greater alcohol craving and risk of relapse. This study also adds scientific context to the growing interest in GLP-1 receptor agonists for addiction treatment. If metabolic dysfunction contributes to alcohol cCravens in certain populations, improving metabolic health could potentially help reduce those cravings.
