Summary

This study used brain scans (fMRI) to see how young adults' brains react to the anticipation and taste of a milkshake compared to a tasteless solution. Researchers focused on reward-related brain regions to identify patterns that might predict obesity risk. The study involved 187 participants and has already been completed.
