The Claim

Liraglutide administered at 3.0 mg per day, combined with a 500 kcal/day deficit diet and exercise, results in a mean weight loss of 7.8 kg from randomization at 1 year in obese non-diabetic adults (BMI 30-40 kg/m², aged 18-65 years), which is significantly greater than placebo (mean difference approximately 4.2 kg) and orlistat (mean difference approximately 2.3 kg).

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

Taking liraglutide 3.0 mg daily along with a reduced-calorie diet and exercise causes an average weight loss of 7.8 kg (about 17 pounds) after one year in obese adults without diabetes. This weight loss is greater than what is achieved with placebo (dummy treatment) or the weight loss drug orlistat.

See the scientific wording

Liraglutide 3.0 mg per day, combined with a 500 kcal/day deficit diet and exercise, produces a mean weight loss of 7.8 kg from randomization at 1 year in obese non-diabetic adults (BMI 30-40 kg/m², aged 18-65 years), which is significantly greater than placebo (mean difference approximately 4.2 kg) and orlistat (mean difference approximately 2.3 kg).

Why this might work

Liraglutide works like a natural hormone in your brain that tells your body you are full. It activates special receptors in parts of the brain that control hunger. This makes you feel less hungry and eat less. Eating less means you take in fewer calories than you burn, so you lose weight.

Supported mechanismbased on 1 study

What the research says

1 study

  1. Study: Tolerability of nausea and vomiting and associations with weight loss in a randomized trial of liraglutide in obese, non-diabetic adults

    The study tested the same dose of liraglutide with diet and exercise in the same type of people and found exactly the weight loss numbers mentioned in the claim, so it supports the claim.
