Age-related declines in insulin sensitivity are driven by increased adiposity rather than chronological age itself.
If you are experiencing worsening insulin sensitivity as you age, focus on managing body fat rather than accepting it as inevitable. This study suggests that maintaining a healthy body weight and composition is more critical for metabolic health than your age number.
GoodRefutesHIGH confidence
The results demonstrate that age-related reductions in insulin sensitivity are likely due to an age-related increase in adiposity rather than a consequence of advanced chronological age.
Why this rating
Randomized controlled trial design with hyperinsulinemic-euglycemic clamp (gold standard), though cross-sectional in nature regarding age groups.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
