What is a GLP-1 medication?

What is a GLP-1 receptor agonist?

GLP-1 stands for glucagon-like peptide-1 — a hormone your gut naturally releases after eating. GLP-1 medications mimic this hormone, amplifying signals your body already uses to regulate appetite and blood sugar.

These medications help by:

• Slowing gastric emptying — food moves through your stomach more slowly, so you feel full for longer after eating
• Reducing appetite — signals your brain that you have eaten enough, making it easier to eat smaller portions
• Regulating blood sugar — stimulates insulin release when blood glucose rises, and reduces glucagon (a hormone that raises blood sugar)

Common GLP-1 medications

| Medication | Brand name(s) | How it's taken | |---|---|---| | Semaglutide | Wegovy, Ozempic | Weekly injection | | Tirzepatide | Mounjaro, Zepbound | Weekly injection (also targets GIP) | | Liraglutide | Saxenda | Daily injection |

Tirzepatide is technically a dual agonist — it targets both GLP-1 and GIP receptors. It works through a similar mechanism but may have a stronger effect on appetite and weight for some people.

How is this different from dieting?

Traditional calorie restriction relies entirely on willpower. GLP-1 medications work at the hormonal level — they change the signals your brain receives about hunger and fullness. Many people describe a noticeable reduction in "food noise" (constant thoughts about food) within the first few weeks.

This is not a willpower shortcut. It is a tool that works alongside lifestyle changes — nutrition, movement, sleep, and stress management still matter significantly.
