Hormonal

Higher postprandial endogenous GLP-1 release is positively correlated with hepatic and peripheral insulin sensitivity in individuals with class II/III obesity without diabetes, and this association persists one year after Roux-en-Y gastric bypass (RYGB).

For individuals with obesity, higher natural GLP-1 responses to meals are linked to better insulin sensitivity. While Roux-en-Y gastric bypass significantly amplifies this GLP-1 response, leading to improved metabolic health, the study suggests that the magnitude of this hormonal response is a key indicator of metabolic status. Non-surgical strategies that might support healthy incretin responses (though not explicitly detailed in this paper) could be beneficial, but the data strongly links the specific postprandial GLP-1 profile to insulin sensitivity.

Why this rating

The study uses gold-standard hyperinsulinemic-euglycemic clamps and stable isotope tracers, though the sample size for the follow-up is small (n=10).
