Summary

This study measured levels of a hormone called pregnenolone and related compounds in the blood of 25 men—some with obesity and some at a healthy weight. Researchers wanted to see if a breakdown in the body's natural feedback loop might lead to overactivity of the endocannabinoid system, which is linked to obesity. The study did not test any treatment; it simply observed differences between the two groups.
