💊 What It Is
Mounjaro (tirzepatide) is a once-weekly injection that helps with weight loss and blood sugar control. It’s a type of medication called a GLP-1 and GIP receptor agonist — meaning it mimics two natural hormones your body already makes to help regulate appetite, digestion, and metabolism.
⚙️ How It Works

Reduces appetite
Mounjaro works on the appetite centres in your brain to help you feel full sooner and stay satisfied longer.
This means you naturally eat less without constant hunger or “food noise.”
Slows digestion
It slows how quickly food leaves your stomach, keeping you fuller for longer after meals.
This also helps control blood sugar levels after eating.
Improves insulin function
Mounjaro helps your body use insulin more effectively and lowers how much sugar your liver releases.
For people with type 2 diabetes, this helps bring blood glucose down.
Supports fat burning
As appetite drops and insulin resistance improves, your body starts using stored fat for energy — leading to steady, healthy weight loss.
🌿 The Result
Fewer cravings and less constant hunger
Improved portion control
Healthier blood sugar levels
Significant and sustainable weight loss when combined with good nutrition and activity
⚠️ Important to Know
It’s not a stimulant or appetite suppressant like older weight-loss pills.
It works with your body’s natural hormones, not against them.
Dosing starts low and increases gradually to help your body adjust and minimise side effects like nausea.
In short:Mounjaro helps your body regain control of hunger and metabolism — allowing you to lose weight naturally, steadily, and safely.
