Landmark Study Shows Lifestyle Changes Cut Diabetes Risk by 58% in High-Risk Adults

The Diabetes Prevention Program tested whether Type 2 diabetes could be prevented in 3,234 high-risk adults across 25 medical centers. Participants with impaired glucose tolerance were randomly assigned to intensive lifestyle intervention, metformin medication, or placebo for 3-6 years. The lifestyle group received personalized coaching on diet, exercise, and weight management. Results showed lifestyle changes reduced diabetes risk by 58%, while metformin reduced risk by 31% compared to placebo. This groundbreaking study established that diabetes prevention is achievable through sustainable behavior modifications, making it one of the most influential prevention trials in modern medicine.
