Understanding the Basics

In the world of weight loss and metabolic health, there’s a lot of confusion around medications, especially when terms like “metformin” and “GLP-1” come up. Many patients ask us:

“Is metformin a GLP-1?”

The simple answer is no. While both may be used in medical weight management settings, they work very differently in the body.

What Is Metformin?

Metformin is a widely used medication that helps support healthy blood sugar levels and insulin sensitivity. It’s often used for individuals who experience insulin resistance or blood sugar imbalances.

Metformin works primarily by:

Reducing how much glucose the liver releases
Improving how your body uses insulin
Supporting metabolic balance

It does not mimic natural hunger-regulating hormones or directly suppress appetite.

What Are GLP-1–Type Treatments?

GLP-1 is a natural hormone in the body that helps regulate appetite, digestion, and blood sugar response. Some medical weight loss treatments are designed to activate GLP-1 receptors, which may help:

Slow down gastric emptying (feel fuller longer)
Reduce food cravings
Support weight loss efforts by improving satiety

These treatments are not the same as metformin, though some patients may benefit from either—or even both—under professional supervision.
