The Diabetes Prevention Program is a pivotal study underscoring the effectiveness of lifestyle modifications in managing and preventing type 2 diabetes.
Step-by-step explanation:
The Diabetes Prevention Program (DPP) was a landmark study designed to investigate ways to prevent type 2 diabetes in individuals at risk. It demonstrated that making significant lifestyle changes, such as moderate weight loss, regular physical activity, and the adoption of a healthful diet, could help control blood glucose levels and prevent the onset of diabetes. This important finding underscores the potential of lifestyle interventions over medication or insulin injections in managing and preventing type 2 diabetes.
