The Claim

In overweight or obese adults with type 2 diabetes treated with basal insulin, liraglutide 3.0 mg in combination with intensive behavioral therapy results in significantly greater mean weight loss of 5.8% from baseline at 56 weeks compared to 1.5% with placebo plus intensive behavioral therapy, with an estimated treatment difference of 4.3 percentage points (p < 0.0001), demonstrating liraglutide's effectiveness as a weight management adjunct in this population.

Cause and effect
1 study reviewed
In plain English

A 56-week study of overweight or obese adults with type 2 diabetes who were already using basal insulin found that those who took liraglutide (3.0 mg daily) plus intensive behavioral therapy lost an average of 5.8% of their body weight from the start of the study. Those who received placebo plus the same behavioral therapy lost only 1.5%. This difference of 4.3 percentage points is statistically significant (p < 0.0001), indicating that liraglutide is an effective weight loss medication for this specific patient group.

See the scientific wording

In overweight or obese adults with type 2 diabetes treated with basal insulin, liraglutide 3.0 mg combined with intensive behavioral therapy induces significantly greater mean weight loss of 5.8% from baseline at 56 weeks, compared to 1.5% with placebo plus intensive behavioral therapy, resulting in an estimated treatment difference of 4.3 percentage points (p < 0.0001). This demonstrates that liraglutide is an effective weight management adjunct in this challenging population.

Why this might work

Liraglutide binds to receptors in the brain and gut that control hunger and digestion. This binding makes you feel full longer and slows how quickly food leaves your stomach. As a result, you eat less and absorb nutrients more slowly, leading to weight loss. Additionally, liraglutide improves blood sugar control, which allows doctors to lower your insulin dose. High insulin doses can cause weight gain, so reducing them further helps you lose weight.

    The study found exactly what the claim says: people taking liraglutide along with diet and exercise lost about 5.8% of their weight, while those on placebo lost only 1.5%, confirming the medication's effectiveness.
