How do GLP-1 receptor agonists cause weight loss?

GLP-1 receptor agonists help people lose weight by slowing down how fast they eat and making them feel full longer.

Imagine you're eating a big bowl of ice cream. Your brain gets the message that it's time to stop eating, but your stomach is still happy with more ice cream. That’s like having a loudspeaker in your tummy saying “more!” while your brain says “enough!”

GLP-1 receptor agonists are like a quiet voice that helps your brain hear better. It tells your brain “Hey, you're already full,” and also slows down how fast food moves through your stomach.

How it works in the body

When you take a GLP-1 receptor agonist, it acts like a helper on your brain’s side. Your brain gets the message faster that you’re full, so you stop eating sooner.

Also, when food moves more slowly through your stomach, you feel full for longer, just like how a big, slow-moving river feels calmer and lasts longer than a quick splash.

So, with help from these helpers, your body learns to eat less and stay full longer, making it easier to lose weight.
