The Claim

Liraglutide at a dose of 3.0 mg daily results in significant weight loss in obese non-diabetic adults after one year, even in the absence of nausea or vomiting, with a mean weight loss of 6.3 kg, which is superior to placebo (mean difference 4.2 kg, p=0.0001) and orlistat (mean difference 2.3 kg, p=0.04).

In plain English

Obese adults without diabetes who take 3.0 mg of liraglutide lose an average of 6.3 kg (about 14 pounds) over one year, even if they do not experience nausea or vomiting. This weight loss is greater than what occurs with placebo or the weight loss drug orlistat.

See the scientific wording

Even without nausea or vomiting, liraglutide 3.0 mg produces significant weight loss in obese non-diabetic adults: participants who reported no nausea/vomiting lost a mean of 6.3 kg at 1 year, which is significantly greater than the weight loss on placebo (mean difference 4.2 kg, p=0.0001) and orlistat (mean difference 2.3 kg, p=0.04).

Why this might work

Liraglutide works by attaching to special receptor sites in the brain that control hunger. This attachment sends signals that reduce appetite and make a person eat less. Even if the person does not feel sick to their stomach (nausea), the drug still turns down the hunger signals, which leads to eating fewer calories and losing weight over time.

  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 found that people taking liraglutide who never felt nauseous still lost about 14 pounds — much more than those on diet alone — showing the drug works even without the unpleasant side effects.
