Sustained weight loss can deliver long-term cardiometabolic benefits in diabetes. A 15-year follow-up published in the Journal of Diabetology found that patients who maintained ≥7% weight loss after an intensive lifestyle program kept better glycemic and lipid control.

The study followed 122 adults with diabetes and obesity who completed a 12-week lifestyle intervention combining dietary guidance, exercise, and behavioral therapy. Participants initially lost an average of 9.6 percent of body weight. At one year, 52.5% maintained at least a 7% reduction.

After 15 years, average weight loss remained 7.6%. Those maintaining ≥7% loss achieved lasting metabolic benefits, with A1C improving from 7.3% to 6.3% at 12 weeks and remaining stable at 7.3% at year 15. In contrast, participants who maintained <7% loss saw A1C rise to 7.9%.

Both groups retained LDL and HDL improvements, though triglycerides worsened in the lesser-loss group. The findings emphasize that modest, sustained weight reduction achieved through structured lifestyle intervention can preserve cardiometabolic health over the long term.
