Ozempic vs Wegovy vs Mounjaro vs Zepbound: Diet & Food Differences Explained

Ozempic, Wegovy, Mounjaro, and Zepbound all slow digestion and quiet appetite — but they're not the same drug, and the day-to-day eating experience can differ between them. Here's what's actually different, what's the same, and how to eat well whichever one you're on.

This is general food and nutrition information, not medical advice. It doesn't compare effectiveness, safety, or which medication is "better" — that's a conversation for you and your prescriber. Always follow their guidance over anything here.

The four brand names, two active ingredients

• Ozempic and Wegovy are both semaglutide — the same drug, at different doses, licensed for different uses (Ozempic for type 2 diabetes, Wegovy for weight management).
• Mounjaro and Zepbound are both tirzepatide — the same drug, at different doses, licensed for type 2 diabetes and weight management respectively.

	Ozempic / Wegovy	Mounjaro / Zepbound
Active ingredient	Semaglutide	Tirzepatide
Receptors targeted	GLP-1 only	GLP-1 and GIP (dual agonist)
Dosing	Once-weekly injection	Once-weekly injection
Common food-related side effects	Nausea, reduced appetite, slower digestion, constipation	Nausea, reduced appetite, slower digestion, constipation
Eating approach that helps	Small, protein-first meals; low-fat, low-sugar; gentle textures	Same approach — small, protein-first meals; low-fat, low-sugar; gentle textures

What's actually different

The mechanism is the key distinction: semaglutide (Ozempic/Wegovy) acts on the GLP-1 receptor, while tirzepatide (Mounjaro/Zepbound) acts on both the GLP-1 and GIP receptors — a "dual agonist." In practice, this means tirzepatide can produce a stronger appetite-suppressing effect for some people, though individual response varies widely and isn't something you can predict from the drug class alone.

Both classes share the same core side-effect profile — nausea, reduced appetite, slower stomach emptying, and constipation are common with all four brands, especially in the first weeks after starting or after a dose increase. Neither is reliably "easier on the stomach" than the other across the board; it depends on the person.

Why the eating advice is the same either way

Because both drug classes slow gastric emptying and suppress appetite through overlapping pathways, the food strategies that help are identical regardless of which one you're on:

• Protein first, every meal — while your appetite is highest, before it fills up on lower-value food.
• Small, frequent meals rather than three large ones — a slow-emptying stomach handles less at once.
• Low-fat, low-sugar, gentle textures — fried, greasy, or very rich food is the most common trigger for nausea on any of the four.
• Fibre and fluids to manage the constipation that comes with eating less overall.

That's why Basilino doesn't publish separate recipes "for Ozempic" versus "for Mounjaro" — every recipe on this site is built around the same small-appetite, high-protein, gentle-texture principles that help on all four medications. See our GLP-1 diet and nutrition guide for the full picture, or jump straight to free GLP-1 recipes.

Common questions

Does switching from semaglutide to tirzepatide change what I should eat? No — the food strategies (protein first, small portions, low-fat, gentle textures) apply to both. Only your prescriber should manage the switch itself, dosing, and titration.

Is one better for nausea? There's no reliable way to predict this per person from the drug class alone; both commonly cause nausea, especially early on and after dose increases. Report severe or persistent nausea to your care team.

Are Ozempic and Wegovy really the same drug? Yes — both are semaglutide, made by the same manufacturer, at different doses and for different licensed uses (diabetes vs. weight management). The same is true of Mounjaro and Zepbound with tirzepatide.
