Type 2 Diabetes Prevention
topic
Type 2 diabetes prevention through dietary and lifestyle modification is the most evidence-supported intervention in preventive medicine — with the landmark Diabetes Prevention Program demonstrating that lifestyle intervention (diet modification and 150 minutes/week physical activity) reduces progression from prediabetes to type 2 diabetes by 58%, compared to 31% for metformin — through the mechanisms of improving insulin sensitivity, reducing visceral adipose tissue, and restoring pancreatic beta cell function before its depletion.
Role
Type 2 diabetes prevention is a public health opportunity of enormous scale — with 88 million American adults currently in prediabetes, the majority unaware of their status — that is dramatically underutilized because prediabetes is rarely screened for systematically and because the lifestyle interventions with the strongest evidence base are almost never prescribed with the same specificity and follow-through as pharmaceutical interventions for established disease. The person who understands their glycemic health status and the specific dietary levers available to reverse prediabetes is equipped to prevent a disease that currently affects 10% of the global adult population — using tools that are free, effective, and available immediately.
