How GLP-1 Medications Work: A Patient’s Guide to Hormonal Weight Loss

GLP-1 medications like semaglutide and tirzepatide are changing the way we think about weight loss—by targeting your biology, not just your willpower. But how do they work? This quick guide breaks it down for you.

Key Takeaways

• GLP-1s mimic a natural hormone that helps you feel full and reduces hunger.

• They slow digestion, helping your body regulate blood sugar and stay satisfied longer.

• Semaglutide (Ozempic®, Wegovy®) and tirzepatide (Mounjaro®, Zepbound®) are the most common options.

• These medications are approved for long-term use in chronic weight management.

• When used alongside healthy habits, they support sustainable weight loss.

What is GLP-1?

GLP-1 (glucagon-like peptide-1) is a hormone your gut naturally releases when you eat. It helps regulate appetite, blood sugar, and digestion. GLP-1 medications mimic this hormone, helping your brain recognize when you’re full sooner and stay full longer, without the mental battle of constant cravings.

What Do These Medications Do?

Here’s how GLP-1 meds support weight loss:

• Appetite Control: They signal your brain to reduce hunger and improve satiety.

• Slow Digestion: They delay how fast food leaves your stomach, helping reduce overeating.

• Stabilize Blood Sugar: They promote insulin and suppress glucagon to keep glucose in check.

Over time, this hormone-driven support helps patients reduce calorie intake, lose weight, and improve metabolic health—all without feeling deprived.

Final Thought
