What to eat on Ozempic or another GLP-1
Appetite drops sharply on GLP-1 medication, so the goal flips: instead of eating less, you have to make the little you eat count. In practice that means protein first at every meal, fluids sipped steadily, fibre for digestion, and small portions that don't overwhelm a slowed stomach.
Why the usual diet advice fails here
Most weight-loss advice assumes you are hungry and need to eat less. On a GLP-1 you are often not hungry at all, and the risk moves to under-eating protein, dehydration and constipation. A plate that looks 'healthy' but is mostly salad can leave you short on the one nutrient that protects muscle.
Build each meal in this order
- Protein first — 25–40 g if you can manage it (chicken, fish, eggs, Greek yogurt, tofu, lentils).
- Vegetables second — cooked rather than raw if raw feels heavy.
- Starch last — rice, potato, bread; include it if you tolerate it, skip it if you don't.
- Fluids between meals, not during — sipping during meals fills a slow stomach fast.
Foods that tend to sit well
| Food | Why it helps | Easy portion |
|---|---|---|
| Greek yogurt (0–2%) | High protein, soft texture, no cooking | 170 g cup |
| Eggs, scrambled or boiled | Complete protein, easy to eat slowly | 2 eggs |
| Chicken or turkey breast | Very high protein per bite | 100–120 g |
| Tinned tuna or salmon | No cooking, high protein | 1 small tin |
| Cottage cheese | Protein + moisture, bland enough to tolerate | 150 g |
| Lentil or bean soup | Protein + fibre + fluid in one | 1 bowl |
| Protein shake with milk | Useful when solid food is impossible | 1 scoop + 250 ml |
Portion ideas only — adjust to what your appetite allows.
Foods that often cause trouble
- Very fatty or fried food — slows stomach emptying further and often triggers nausea.
- Large volumes of raw vegetables or salad — filling without much protein.
- Fizzy drinks — gas plus a slow stomach is uncomfortable.
- Alcohol — adds calories, worsens dehydration, and can worsen nausea.
- Very spicy or acidic food if you already have reflux.
Hydration and fibre
Constipation is one of the most common complaints. Aim for fluids spread across the day (not gulped at meals), and build fibre gradually from fruit, oats, lentils and vegetables. If stools are hard despite that, talk to your clinician — do not self-prescribe laxatives long-term.
Track protein, not just calories
Calories will take care of themselves when appetite is suppressed. Protein will not. Use the protein calculator to set a daily gram target, and check it at the end of the day rather than counting every bite.

Frequently asked questions
How much protein should I aim for on a GLP-1?▾
A common target is 1.2–1.6 g per kg of body weight per day, which is higher than the general adult minimum because you are eating in a deficit and want to protect muscle. Use the protein calculator for a number, then confirm it with your clinician.
I can only eat a few bites. What should those bites be?▾
Protein. If you can only manage 300 calories in a meal, make them mostly protein — a shake, yogurt, eggs or fish. Vegetables and starch can fill in later as appetite returns.
Is nausea a sign I ate the wrong thing?▾
Not necessarily. Nausea is a known effect of the medication and is often worse with fatty, fried or very large meals. Smaller, drier, lower-fat meals usually help; persistent vomiting needs medical review.
Can I exercise while eating this little?▾
Gentle activity is usually fine and helps appetite regulation. Strength training is worth keeping if you can, because it is the main signal telling your body to keep muscle. If you feel dizzy or exhausted, eat more protein and speak to your clinician.
