Lifestyle Beats Medicines In Long-Term Diabetes Prevention

A 20-year study shows lifestyle changes outperform metformin in preventing type 2 diabetes. Initiated in 1996, it revealed a 58% diabetes reduction from healthy habits versus 31% with metformin. Participants gained up to 3.5 extra diabetes-free years. Researchers say lifestyle changes are more effective and sustainable than medication for long-term diabetes prevention.
