You might have heard of Mounjaro, Ozempic, and Wegovy—these are GLP-1 medications that help with weight loss. But how do they work, and how can healthy eating make them more effective? Discover how balanced, nourishing meals support those on GLP-1 medication. Learn what to eat for energy, satisfaction and long-term success.

GLP-1 Medications: Why Nutrition Matters

Mounjaro, Ozempic, and Wegovy are medications that help with weight loss and diabetes management. But how do they work, and what role does diet play when using these medications?

What are GLP-1 and Dual GLP-1 & GIP Medications?

GLP-1 stands for Glucagon- Like Peptide. GLP-1 is a hormone that's produced in the gut in response to a meal. It plays a role in helping you feel full and regulating your blood glucose after eating.

GLP-1 medications are self injected and mimic the body’s own GLP-1 and GIP to help treat type 2 diabetes and/or people living with obesity.

How do they help with weight loss?

These injections aid weight loss by:

-slowing down your stomach emptying so food stays in your stomach longer, keeping you full

-reducing your appetite so you eat less

-reducing the amount of glucose produced by your liver which can help manage cravings as your blood sugar is kept stable

The medications are most effective alongside lifestyle changes such as healthy, balanced diet and exercise.

How can GLP-1’s affect your nutrition?

Not everyone experiences side effects of GLP-1’s but some may struggle to eat balanced meals and maintain hydration.

Eating 2-3 balanced meals a day should be enough to meet your nutritional needs but see our GLP-1 nutrition guide for more advice and the importance of focusing on the quality of your diet.
