Healthy Lifestyle Beats Anti-Diabetes Drug Metformin Over Long Term: Study

A landmark study published in The Lancet Diabetes & Endocrinology has revealed that adopting a healthy lifestyle significantly outperforms the anti-diabetes drug metformin in preventing type 2 diabetes over a span of more than two decades. The research was led by a team that included scientists from The University of New Mexico, US.

Study Overview:

• Study Initiated: 1996


• Participants: 3,234 individuals with prediabetes


• Institutions Involved: 30 centers across 22 US states


• Comparison: Intensive lifestyle changes vs. metformin use

Key Findings:

• Lifestyle modification lowered diabetes development by 24%, compared to 17% for metformin.


• In the first three years, lifestyle changes led to a 58% reduction in diabetes onset, while metformin showed a 31% reduction.


• Participants who adopted lifestyle changes gained 3.5 years of diabetes-free life, while those on metformin gained 2.5 years.


• The benefits were sustained even 22 years after the study began.

Expert Insight:

“Within three years, they had to stop the study because lifestyle was better than metformin,” said Vallabh Raj Shah, professor emeritus at The University of New Mexico’s School of Medicine.
“That means lifestyle, which everybody is banking on, is more effective — that is the news.”

Conclusion:

The findings underscore the long-term power of preventive health habits like regular physical activity, healthy eating, and weight management over pharmaceutical intervention alone. According to the authors, lifestyle interventions not only reduced the incidence of diabetes more effectively but also provided longer-lasting protection against the disease.

This study strongly supports the global push for preventive healthcare approaches, especially for populations at risk of developing type 2 diabetes.
