The Claim

In overweight/obese patients with newly diagnosed type 2 diabetes and stable coronary artery disease, the addition of liraglutide to metformin does not improve insulin sensitivity (Si) or glucose effectiveness (Sg), despite inducing a weight loss of −2.7 kg, and beta-cell function improvements occur independently of changes in Si or Sg.

How it works
1 study reviewed
In plain English

In overweight or obese adults with newly diagnosed type 2 diabetes and stable heart disease, adding liraglutide to metformin does not improve how well the body uses insulin or how effectively glucose is processed, even though it causes a small amount of weight loss, and improvements in insulin production by the pancreas happen without changes in insulin sensitivity or glucose effectiveness.

See the scientific wording

Liraglutide added to metformin does not improve insulin sensitivity (Si) or glucose effectiveness (Sg) in overweight/obese patients with newly diagnosed type 2 diabetes and stable coronary artery disease, despite significant weight loss of −2.7 kg, indicating that beta-cell improvements occur independently of changes in these parameters.

Why this might work

Liraglutide binds to receptors on insulin-producing cells in the pancreas, which triggers a chain reaction that increases calcium inside the cells. This causes the cells to release more insulin quickly after eating. This boost in insulin happens even though the body's ability to use insulin or clear sugar without insulin does not change, and even when a small amount of weight is lost.

    Even though the drug helped people lose a little weight, it didn’t make their bodies better at using insulin or clearing sugar without insulin. But it did help their pancreas make more insulin — meaning the pancreas got better on its own, not because of the weight loss.
