Frequently asked questions

What is GLP-1?

GLP-1 (glucagon-like peptide-1) is a gut hormone released after eating that promotes satiety, slows gastric emptying, and stimulates insulin. GLP-1 receptor agonist medications mimic and amplify this signalling.

How do GLP-1 medications cause weight loss?

They reduce energy intake by enhancing satiety, slowing stomach emptying, and acting on brain appetite and reward circuits — so people feel full sooner, stay full longer, and think about food less. The effect lasts while the medication is taken.

What happens if you stop taking a GLP-1?

Appetite typically returns and much of the lost weight tends to be regained, because the underlying biology that defends higher weight is unchanged. This is why obesity medicine increasingly frames treatment as ongoing rather than time-limited.
