In this blog, our Registered Dietitian working with Inside Out Nutrition, Ellen Curran, breaks down exactly what individuals in Ireland need to know about managing their GLP-1 nutrition while using medications like Ozempic, Mounjaro, or Wegovy, while separating the real clinical science from the marketing hype.
Read on to discover the essential nutritional strategies needed to support your health and manage side effects effectively.
Medications such as semaglutide (Ozempic/Wegovy), liraglutide (Saxenda), and tirzepatide (Mounjaro/Zepbound) are increasingly utilised in Ireland to support those living with obesity. Obesity is a complex, long-term condition that can increase the risk of type 2 diabetes, heart disease, and fatty liver disease. While these medications provide a powerful tool for change, they work most effectively when paired with a robust nutritional foundation.
These treatments work with your body’s natural systems to regulate appetite and blood sugar. Many people notice they feel less hungry, reach satiety more quickly, and enjoy more stable energy levels after eating. When combined with supportive nutrition and lifestyle habits, these medications can lead to meaningful and sustainable health changes over time.
However, it is important to remember that they are not a “quick fix.” Because your appetite is reduced, you will likely eat significantly less overall. While this supports weight goals, it can make it harder to consistently meet your body’s requirements for vitamins, minerals, and protein. This is where clinical nutrition becomes vital, as we focus on eating patterns that ensure you feel well, energised, and nourished throughout your journey.
GLP-1 medications mimic a natural hormone in your gut that influences appetite, digestion, and blood sugar regulation. Rather than working in just one way, they act across several systems in the body to support how you feel and respond to food.
In practice, this means they:
Some medications, such as tirzepatide, also act on an additional metabolic pathway involved in insulin sensitivity. This dual action further supports appetite regulation and blood sugar control. It is also very common to experience digestive side effects at the beginning of treatment or when your dose increases. These can include nausea, constipation, or reflux, though for most people, these improve as the body adjusts.
Even if you are eating smaller portions, your meals can still be satisfying. A helpful visual for your plate is to divide it into Protein + Fibre-rich Carbohydrates + Vegetables + Healthy Fats. Fibre-rich carbohydrates provide the sustained energy your brain needs. Excellent Irish staples include oats, wholegrain breads or bagels, potatoes with the skins left on, and brown rice. Adding healthy fats such as olive oil, avocado, or oily fish supports hormone health and the absorption of essential vitamins.
Sample Day of Eating:
Side effects are common during the early stages of GLP-1 therapy, but there are simple ways to support your body through the transition:
Because you may be eating less while on these medications, it can sometimes be harder to meet all your vitamin and mineral needs consistently. Rather than guessing or relying on high-street marketing, it is helpful to check in with your GP or a Registered Dietitian to base any supplementation on your individual clinical needs.
When appetite is suppressed, certain nutrients are worth reviewing to ensure your body remains resilient:
While a general multivitamin may be a useful “safety net” for some people, it works best when used alongside a varied and balanced way of eating. We recommend regular blood tests to ensure your levels are optimal throughout your treatment journey.

GLP-1 medications are a helpful support tool, but clinical nutrition is what underpins how you feel day to day and supports your long-term health. Prioritising your intake helps you maintain muscle, support energy levels, and build habits that last far beyond the medication.
If you’re taking a GLP-1 medication and trying to find your rhythm with food, you don’t have to figure it out alone. With the right support, it can feel much more manageable and far less overwhelming. Our team of experienced Registered Dietitians are here to help.
