A ketogenic (keto) diet keeps carbohydrates very low — typically under 50 grams a day, sometimes as low as 20 — so the body relies more on fat for fuel.[1] At a restaurant that usually means building the meal around protein, non-starchy vegetables, eggs, cheese, and fats, and skipping bread, rice, pasta, potatoes, sugar, and sauces thickened or sweetened with them. The approach began in medicine: ketogenic diets were developed in the 1920s to treat epilepsy.[2] This guide is about ordering, not medical advice; talk to a clinician before using keto for a health condition.
Confirm certification, ingredients, and allergens with the restaurant. For severe allergies, speak to staff in person before ordering; menu descriptions and SeEat are not a safety guarantee.
Editorial review ·
What to order
- Steak or grilled fish with buttered vegetables — a common keto order
- Burgers without the bun — lettuce-wrapped where offered
- Korean barbecue meats — skip the rice and sweet marinades like galbi
- Salads with olive oil, avocado, cheese, and a protein — dressing on the side
- Charcuterie and cheese boards — skip the bread and dried fruit
Keto takeout: choose an adjustable order
For lower-carbohydrate takeout, ask about an unbreaded main with vegetables, then request rice, noodles, or bread separately. This is an ordering approach, not a measured carbohydrate total or a medical diet plan.
What to check
- Check sweet glazes and dipping sauces: sweet-and-sour and sweet-chilli takeaway dishes may contain substantial sugar.[3]
- An app note may be missed; call the restaurant to confirm changes and unavailable substitutions.
Questions for the restaurant
- Can I swap the rice or fries for non-starchy vegetables?
- Is the meat breaded or marinated, and can the sauce come separately?
- Do you have nutrition information for the actual portion and customizations?
Frequently asked questions
What can I eat at a restaurant on keto?
Start with an unbreaded protein and non-starchy vegetables: steak, roast chicken, grilled fish, eggs, or a salad with an oil-based dressing. Swap fries or rice for greens, and ask about sweet marinades and glazes.
Which cuisines are hardest — and easiest — for keto?
Hardest: pasta-centric Italian, rice-centric Asian menus, and anything battered. Easiest: steakhouses, Brazilian churrascarias, Greek grills, and breakfast-all-day spots with egg dishes.
Where do hidden carbs show up in restaurant food?
Sweet marinades (teriyaki, galbi, barbecue sauce), flour-thickened sauces and soups, breading, and “healthy” bowls built on rice or quinoa. Takeaway sauces such as sweet-and-sour can also carry a lot of sugar.[3]
Does removing rice establish a carbohydrate count?
No. Portion size, marinades, breading, and sides still need checking. Ask for the restaurant’s nutrition information for your intended order.
How does this differ from medical ketogenic therapy?
Ketogenic diets have a clinical history in epilepsy care. Medical treatment requires a clinician’s guidance; restaurant substitutions are not that treatment.[2]
