Summary

This pilot study tested whether adding protein supplements twice a day could reduce cravings in 28 people hospitalized for addiction. Participants spent one week with protein and one week without, rating their cravings on a simple scale. The goal was to see if a simple dietary change might help during early recovery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If it works, this could point toward a simple dietary aid to help manage cravings during early addiction treatment.
