What to eat on a GLP-1 when you're not hungry

A quiet appetite is the medication doing its job, and eating less is expected. The goal is to make the smaller amount you eat work well for you.

How much less do people eat?

In clinical trials, people on these medications ate 16 to 39% less energy than people on a placebo.

That figure comes from a 2025 joint advisory from four nutrition and obesity medicine groups. Some days, you might forget to eat at all.

Why do I still need a plan if I’m not hungry?

Because eating very little makes it harder to get enough protein, vitamins and minerals.

The advisory lists long stretches without meals as something to avoid. It flags a higher risk of falling short below about 1,200 calories a day for women or 1,800 for men. You don’t need to count calories; “barely eating” just isn’t the aim.

When should I eat?

On a loose schedule of small, regular meals, instead of waiting for hunger.

• Pick your times. Three small meals and one or two snacks is a common rhythm.
• Set a reminder. A phone alarm at lunch helps on busy days.
• Start small. Half a sandwich counts. So does a cup of yogurt with fruit.
• Stop when comfortably full. See gentle meals for queasy days.

What should I eat first?

Protein first, then fruit, vegetables or whole grains.

Protein helps protect muscle; the rest brings fiber, vitamins and minerals. The advisory suggests 1.2 to 1.6 grams of protein per kilogram of body weight a day while losing weight. The protein guide explains how to find your number.

Small plates that carry a lot

Top yogurt with berries and nuts, or put eggs on whole-grain toast. Tuna or chicken salad on crackers, bean soup, or tofu or paneer in a small curry also work. For more, try the protein finder.

What if chewing feels like too much?

Drinks and soft foods can bridge the gap.

Try a smoothie with milk or yogurt and fruit, a soy drink with protein, or soup with beans, lentils or shredded chicken.

Some people meet protein targets with shakes, bars and fortified foods. They’re a helpful backup, but whole foods bring fiber and other nutrients too.

How can I make eating easier on low-energy days?

Keep ready-to-eat food within reach so there’s less to decide.

Boil a few eggs for the week, keep canned tuna, salmon or beans in the cupboard, and cook a batch of chicken, tofu or lentils. A simple grocery list keeps them stocked.

Do I need to drink more?

Yes, eating less can mean drinking less without noticing.

The advisory encourages adequate fluids. Keep a water bottle nearby and sip through the day.

What signs should I mention to my doctor?

Unusual tiredness, hair loss, dry skin, weakness or slow healing can mean nutrition is falling short.

The advisory also lists dry, flaky or itchy skin and unusual bruising. If you notice any of these, or eating enough feels hard most days, talk to your doctor or a registered dietitian. They can check whether a supplement makes sense for you.

What about the off days?

They’re normal, and the pattern over weeks matters more than any one day.

Some days a yogurt and a few crackers is the best you can manage. Imi plans meals like this for you each week, sized for how you actually eat. For the full picture, see eating well on a GLP-1.
