Mounjaro & Wegovy Dietitian UK
GLP-1 Nutrition Support

GLP-1 injections or tablets: already on treatment, or considering it?

You may have already started Mounjaro or Wegovy, as an injection or in the newer tablet form. You may have an appointment with your doctor coming up and be getting ready to start. Or you may simply be thinking about it and want to understand what it would mean for your eating and your day-to-day life.

If you’ve already started, you may be eating so little that you’re not sure you’re getting what your body needs. You may be dealing with nausea, tiredness or constipation, and wondering what will happen when you stop. Or perhaps you got your prescription from an online pharmacy, but with no guidance on what to eat.

GLP-1 medications are an effective tool, but nutrition plays a big part in how you feel during treatment, how your body composition changes as you lose weight, and how well you can sustain your progress once treatment ends. That’s why NICE recommends combining these medications with support for diet and physical activity. And the earlier that support begins, ideally before your first dose, the smoother things tend to go.

I’m Maria Kolotourou, an HCPC-registered dietitian with over 20 years of experience. I can help you get the most from your treatment in a way that protects your health and fits your life.

Why work with a dietitian while on GLP-1 medication?

GLP-1 medications reduce your appetite, but not your body’s nutritional needs. When you’re eating much less, it’s easy to fall short on protein, fibre, vitamins and minerals without realising it.

You can also lose muscle along with fat, especially if your protein intake is low and you’re not doing any resistance exercise. Muscle matters for your metabolism, your energy levels and your long-term health.

There’s an upside, too. When the constant “food noise” quietens down, you have a real opportunity to build habits that will last well beyond your treatment.

Making GLP-1 treatment work in real life

Many people start treatment through a private or online pharmacy, where nutritional support is often limited to a leaflet, if there’s any at all. But the real challenges tend to show up in everyday life:

• Social occasions and family meals: Christmas, birthdays, holidays, and relatives saying “you’ve barely eaten anything!” How to enjoy these moments when your appetite is small.
• Busy days: Quick lunches at work, supermarket ready meals and a pace of life that leaves little time for cooking.
• Food traditions and fasting: How to keep the dishes you love, and how to meet your needs during religious fasting periods when you’re only eating small portions.
• The Mediterranean way of eating: Pulses, fish, vegetables, yoghurt and olive oil are a natural fit for GLP-1 treatment, offering plenty of nutrition in small portions.

I work with many Greeks living abroad, as well as people from any background who’d like a Mediterranean approach.

How nutrition helps

Enough protein in small portions

Practical ways to meet your protein needs, even when your appetite is small.

Protecting your muscle

Protein combined with resistance exercise, adapted to your level.

Nausea, constipation and bloating

Nutrients

Variety and quality on your plate, so nothing important is missing.

Life after treatment

When your treatment stops, there’s a real risk that your appetite and weight return. A plan that starts early makes that transition much smoother. Read more in my article After Mounjaro or Ozempic: How to Prevent Weight Regain.

I work with people who are:

• Thinking about treatment: You’d like to understand what GLP-1 medication means for your nutrition before making a decision with your doctor.
• About to start: You’d like to prepare in advance so the first few weeks feel easier.
• Already on treatment: Injections or tablets, through the NHS, a private doctor or an online pharmacy.
• Stopping or have stopped: You’d like support to hold on to as much of your progress as possible.
• Living with PCOS, insulin resistance or perimenopause, and on or considering GLP-1 treatment.

Planning a pregnancy? GLP-1 medications need to be stopped before you start trying to conceive, and Mounjaro can make the contraceptive pill less effective. It’s important to discuss your circumstances with your doctor. I can help with nutritional preparation through my Fertility & Pregnancy Nutrition Programme.

What you should know

I don’t prescribe, and it isn’t my role to advise on which medication or dose is right for you. Decisions about starting, the type of medication, the dose and stopping are for your doctor or pharmacist. My role is nutrition and everyday life, so that your treatment properly supports your health.

If you have a history of an eating disorder, it’s especially important to tell your doctor (and me) before you start, as support needs a different approach in this case.
