The Claim

Semaglutide is associated with significantly greater weight loss compared to liraglutide in both diabetic and non-diabetic populations, with a meta-regression coefficient of β = +1.67 (p < 0.001) favoring semaglutide after adjustment for other variables.

Source: Differential impact of glucagon-like peptide-1 (GLP-1) receptor agonists for weight loss in the type 2 diabetic and non-diabetic populations.

In plain English

Semaglutide leads to more weight loss than liraglutide in people with or without diabetes, based on combined data from multiple studies. The difference is statistically significant, meaning it is unlikely to be due to chance.

See the scientific wording

Semaglutide is associated with significantly greater weight loss compared to liraglutide in both diabetic and non-diabetic populations, with a meta-regression coefficient of β = +1.67 (p < 0.001) favoring semaglutide after adjustment for other variables.

Why this might work

Semaglutide is a medicine that stays in the body longer and sticks tighter to its target, a special sensor for a natural hormone. This sensor tells the brain 'you are full' and slows down stomach emptying. Because semaglutide activates this sensor more strongly and for longer than liraglutide, it makes people feel fuller longer and absorb fewer calories, leading to greater weight loss.
