The Claim

In adults with type 2 diabetes, once-daily subcutaneous liraglutide at doses of 0.6, 1.2, and 1.8 mg reduces postprandial plasma glucose levels by 25-35% compared to placebo over five hours after a standardized meal, due to enhanced insulin secretion and delayed gastric emptying.

Cause and effect
1 study reviewed
In plain English

In adults with type 2 diabetes, daily injections of liraglutide at doses of 0.6, 1.2, or 1.8 mg lower blood glucose levels after meals by 25-35% compared to a placebo, through increased insulin release and slower stomach emptying.

See the scientific wording

In adults with type 2 diabetes, once-daily subcutaneous liraglutide at doses of 0.6, 1.2, and 1.8 mg significantly reduces postprandial plasma glucose levels by 25-35% compared to placebo, as measured over five hours after a standardized meal, likely due to enhanced insulin secretion and delayed gastric emptying, which are key mechanisms for improving glycemic control after meals.

Why this might work

Liraglutide binds to receptors in the pancreas and stomach, causing the pancreas to release more insulin after meals and slowing down how fast food leaves the stomach. This means sugar from food enters the bloodstream more slowly and more insulin is available to remove it, resulting in lower blood sugar spikes after eating.

    This study found that a daily liraglutide shot lowered blood sugar spikes after meals by 25–35% in people with type 2 diabetes, just like the claim says — and it did so by helping the body release more insulin and slowing down digestion.
