The Claim
In individuals with obesity and prediabetes, daily administration of liraglutide at 1.8 mg for 14 weeks causes a rapid, weight loss–independent improvement in insulin sensitivity, as measured by HOMA-IR, HOMA2, and Matsuda index, with significant improvements observed within 2 weeks prior to measurable weight loss, and these effects are reversed by GLP-1 receptor blockade, indicating a direct GLP-1 receptor–mediated mechanism.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with obesity and prediabetes, a daily dose of liraglutide improves how the body responds to insulin within two weeks, before any significant weight loss occurs, and this improvement is blocked when the GLP-1 receptor is inhibited.

Liraglutide binds to GLP-1 receptors on liver and fat cells, which tells the liver to make less sugar and tells muscles and fat to take up more sugar from the blood. It also blocks the pancreas from releasing too much glucagon, a hormone that tells the liver to release more sugar. This happens quickly, before any weight loss, and stopping the GLP-1 receptor reverses all these effects.
What the research says
1 studyIn people with obesity and prediabetes, liraglutide helps the body use insulin better within two weeks—even before they lose weight—and this effect stops when a blocker is given, proving it works through the GLP-1 receptor.
