Mounjaro (Tirzepatide) is a GLP-1/GIP receptor agonist that helps regulate blood glucose and reduce appetite. Many people experience fewer cravings early on, so when hunger returns or persists, it can feel unexpected.
But here’s the truth: some hunger is normal - even on Mounjaro. The medication is designed to help manage appetite, not eliminate it completely. If you’re still feeling hungry, it doesn’t mean something is wrong, it may simply mean your body needs support, adjustment, or nourishment.
Why you might be still hungry on Mounjaro
1. Your Dose May Need Adjustment
If you're early in treatment or on a lower dose, appetite suppression may not be fully effective yet. Mounjaro doses are increased gradually, and it can take time to find what works best for your body.
2. Your Body’s Still Adapting
After a dose increase, it may take days or weeks for your body to adjust. Some hunger or cravings during this time are completely normal.
3. Emotional or Habitual Hunger
Not all hunger is physical. Stress, boredom, and routine eating can trigger cravings that medication doesn’t change. Mindful eating practices can help you recognise the difference.
4. Your Eating Patterns May Need Support
Even with less appetite, your body still needs fuel. Especially protein, fibre, and essential nutrients. Skipping meals or eating mostly ultra processed foods can increase hunger and affect blood glucose stability.
How to support Mounjaro’s effectiveness
Eat a Balanced, Nutrient-Dense Diet
Focus on protein, fibre-rich carbohydrates, and healthy fats to promote satiety and stable blood glucose.
Stay hydrated
Aim to drink 6 to 8 glasses of fluid throughout each day. This is particularly important if you experience nausea. Adequate water intake also helps to support digestion.
Eat Mindfully
Eat slowly, chew thoroughly, and listen to your hunger and fullness cues. Distraction-free meals can help prevent overeating and promote satisfaction.

With the right dose, balanced nutrition, and awareness of your body’s signals, Mounjaro can be a powerful tool in your health journey.
