Introduction
Starting on Mounjaro is a big step whether you are trying to lose weight, control diabetes, or do both. But along with the injections you receive once a week, there is one thing that counts just as much, what you eat, just in case you were wondering.
This guide breaks it all down in a straightforward, no fuss way. From smart food choices to meals and snacks ideas, we will guide you on how to eat to get the best out of your Mounjaro experience and keep you energised.
Let’s get started.
How Mounjaro Aids Weight Loss
Mounjaro (tirzepatide) is a weekly injection that acts like two important hormones, the GLP-1 and GIP. These hormones regulate blood sugar levels, and slow digestion, so you feel fuller, longer. The result? Decreased appetite, improved blood sugar levels, and most importantly for many, consistent weight loss.
It is given to help control type 2 diabetes and sometimes obesity, and is commonly used in the UK for medically supervised weight loss programmes. But drugs are not a cure all by themselves. Your results will be much better if you have the right balanced diet.
Importance of Diet While Using Mounjaro
What you eat has a lot to do with how much Mounjaro can help you out. Because the medication slows gastric emptying, the key is to stick with foods that are dense in nutrients yet easy on your digestive system. You are going to want to fuel your body with meals that provide for more consistent energy, help you stay full for longer, and do not have side effects like nausea or bloating.
So we have put together this quick guide of 10 healthy food options and easy meal ideas that fit with Mounjaro’s principles and mechanisms.
