When appetite is low on a GLP-1 medication, prioritise small, protein-dense meals over large or low-nutrient ones — liquid or soft protein sources like Greek yoghurt, smoothies, eggs, and bone broth are easier to manage than a full meal and still protect your muscle. The goal isn't to eat more. It's to make what you do eat count.

Why this is harder than it sounds

Most nutrition advice assumes you're working against hunger — willpower, portion control, resisting cravings. On a GLP-1, you're working against the opposite problem: your body genuinely isn't asking for food, sometimes for most of the day. That's the medication doing exactly what it's meant to do. But it creates a new, less-discussed problem: how do you eat enough of the right things when you don't want to eat much of anything?

The reframe that helps

Stop thinking about meals. Start thinking about protein opportunities throughout the day. If three traditional meals feels like too much, aim for four or five small protein-first moments instead — each one doing a specific job (hitting 20–30g of protein) rather than trying to be a complete, balanced meal.

Low-effort, low-appetite protein options

• Liquid protein — a protein smoothie, a high-protein yoghurt drink, or bone broth. These go down easily even with low appetite or mild nausea.
• Greek yoghurt — naturally high in protein, soft, and doesn't require any preparation.
• Eggs — quick to cook, versatile, and one of the most efficient whole-food protein sources available.
• Cottage cheese — often overlooked, but delivers a meaningful protein hit in a small volume.
• Canned fish — tuna or salmon straight from the tin requires zero cooking and travels well if you're not eating at home.

Don't skip breakfast, even if you're not hungry

Your overnight fast means your muscles are already waiting for fuel by morning. Skipping breakfast on top of an already-reduced overall intake compounds the protein gap for the rest of the day. It doesn't need to be large — even a small protein-first breakfast matters more than skipping to "save room" for later.

A pro tip from clinical practice

If you're genuinely struggling to hit your target through food alone, a protein shake counts — as a last resort, not a first choice, but consistency matters more than perfection. Missing your target because the "right" food didn't appeal to you is a worse outcome than a shake that actually gets consumed.

The bottom line

Low appetite isn't a problem to push through with willpower — it's a structural eating challenge that needs a different strategy than the one you used when you were hungry. Small, protein-dense, low-effort choices, repeated through the day, beat three meals you're forcing yourself to finish.
