Summary

This study looked at whether saliva can be used to measure endocannabinoids—natural chemicals linked to appetite and weight—instead of taking blood. Researchers compared 12 obese and 12 normal-weight adults after fasting. The goal was to see if saliva levels differ between the groups and if saliva is a reliable tool for studying obesity.
