Summary

This study tested a new weight loss program called Med-South, which adapts the Mediterranean diet for Southern tastes, against the popular WW (Weight Watchers) program. Over 360 adults with obesity participated for 2 years, with researchers tracking weight loss, blood markers, and fruit/vegetable intake. The goal was to see if Med-South could help people lose weight and improve heart health.
