Part 3: Insulin resistance & weight loss
So… what do GLP-1s actually do?
By now you’ve probably heard about GLP-1 medications for weight loss—but what’s really happening in your body?
GLP-1 stands for glucagon-like peptide-1, a hormone your body already makes. These medications simply mimic and amplify what that hormone does naturally.
Here’s how they help:
• They slow down digestion
Food stays in your stomach longer, so you feel full sooner and stay full longer.
• They reduce appetite signals
GLP-1s act on the brain to quiet “food noise”—less constant thinking about eating, fewer cravings.
• They improve insulin response
Your body releases insulin more effectively when you eat, helping stabilize blood sugar instead of spiking and crashing.
• They lower glucagon
Glucagon raises blood sugar. GLP-1s help reduce it, keeping levels more balanced.
• They indirectly support fat loss
By lowering insulin spikes and reducing overeating, your body has a better chance to access stored fat.
This is why GLP-1s can be especially helpful for people with insulin resistance—not because they’re “magic,” but because they address the underlying biology.
Important: they don’t replace lifestyle habits. They support them.
