The Claim

GLP-1 receptor antagonism with exendin(9-39) reverses liraglutide-induced improvements in insulin sensitivity and increases postprandial glucose and glucagon levels in individuals with obesity and prediabetes.

How it works
1 study reviewed
In plain English

Blocking GLP-1 receptors with exendin(9-39) eliminates the improvement in insulin sensitivity caused by liraglutide and raises blood glucose and glucagon levels after meals in people with obesity and prediabetes.

See the scientific wording

GLP-1 receptor antagonism with exendin(9-39) reverses liraglutide-induced improvements in insulin sensitivity and increases postprandial glucose and glucagon levels in individuals with obesity and prediabetes, confirming that these metabolic effects are dependent on continuous GLP-1 receptor activation.

Why this might work

When GLP-1 binds to its receptor, it tells the pancreas to stop releasing glucagon and makes the liver and muscles more responsive to insulin. This lowers blood sugar after meals. If the receptor is blocked, glucagon rises, insulin sensitivity drops, and blood sugar spikes.

  1. Study: Weight Loss-Independent Effect of Liraglutide on Insulin Sensitivity in Individuals with Obesity and Pre-Diabetes.

    When scientists blocked the GLP-1 receptor in people taking liraglutide, their blood sugar went up and their body’s ability to use insulin got worse — proving that liraglutide only works if the receptor stays active.
