Keto Fast Food: What to Order at 12 Popular Chains

Yes, you can eat fast food on keto. Order burgers and sandwiches without the bun, grilled chicken, salads with full-fat dressing, and breakfast meats with eggs. Skip the fries, buns, tortillas, sugary drinks, and sweet sauces. The universal trick that works at almost every chain: "bunless or lettuce-wrapped, hold the fries."

Fast food gets a bad reputation on keto, but the carbs are almost entirely in the parts you can leave off — the bun, the breading, the fries, and the sauce. Strip those away and you're left with protein and fat, which is exactly what keto runs on. Here's what to order at 12 of the most popular chains.

Best keto orders by chain

Net carbs are estimates and vary by location and portion. When precision matters, log the exact item — our fast-food carb database has values for hundreds of chain menu items, including the Big Mac.

Keto at McDonald's

McDonald's is one of the easiest drive-thrus to keto because every burger can go bunless and the breakfast menu is full of eggs and meat.

• Quarter Pounder with Cheese, no bun, no ketchup — ask for a fork or eat it as a "burger bowl."
• Double Quarter Pounder for more protein, still no bun.
• Bunless McDouble — a cheap, low-carb default.
• Sausage McMuffin with Egg, no muffin — order it "no English muffin" for a clean breakfast.
• Side salad with a full-fat dressing (skip the low-fat and sweet vinaigrettes).

Watch the ketchup and "special sauce" — both carry added sugar. A plain Big Mac without the bun and middle bun is fine if you hold the sauce or use only a little.

Keto at Chipotle

Chipotle is a keto favorite because you build the bowl yourself. Start with a bowl (no tortilla, no taco shell) and skip the rice and beans entirely.

• Protein: carnitas, steak, chicken, or barbacoa.
• Add fats: cheese, sour cream, and guacamole (guac is essentially free carbs-wise and adds satiety).
• Veg: fajita vegetables and a scoop of fresh tomato salsa.
• Skip: rice, beans, corn salsa, and the chips.

That combination lands most people around 8g net carbs with a big payload of protein and fat.

Keto at Starbucks

Coffee is naturally keto until syrups and milk get involved. The fix is simple.

• Americano, espresso, or brewed coffee — add heavy cream instead of milk.
• Unsweetened iced tea or cold brew (skip the sweet cream and flavored syrups).
• Sugar-free syrup if you want flavor, in moderation.
• Egg bites (the bacon & gruyère are about 9g net carbs) for a grab-and-go meal.

Avoid the obvious traps: Frappuccinos, flavored lattes, and anything labeled "vanilla sweet cream" can run 30–50g of carbs in a single cup.

How to order keto anywhere

You don't need a chain-by-chain cheat sheet if you remember a few rules:

1. Go bunless or lettuce-wrapped. This single swap removes the biggest carb source from any sandwich or burger.
2. Hold the fries. Substitute a side salad, or just skip the side.
3. Choose grilled over breaded or crispy. Breading is flour, and flour is carbs.
4. Pick water, unsweetened tea, diet soda, or black coffee. Sugary drinks can blow your whole day's carb budget.
5. Add fat, not starch. Cheese, avocado, mayo, and full-fat dressing keep you full.

Hidden carbs to watch

Most accidental carbs on keto fast food come from a handful of culprits:

• Sauces and dressings. Ketchup, BBQ, honey mustard, "special sauce," teriyaki, and most low-fat dressings are loaded with sugar. Ask for mayo, ranch, Caesar, or oil and vinegar instead.
• Breading and batter. Crispy chicken, popcorn shrimp, onion rings, and tempura are flour-coated. Always choose grilled.
• "Healthy" sides. Fruit cups, baked beans, coleslaw with sweet dressing, and corn are higher-carb than they look.
• Glazes and marinades. Some grilled items are brushed with sugary glaze — ask, and request it plain if you're unsure.

The carb counts on these add up fast and aren't always obvious, which is exactly why logging matters.

Log it before you leave the drive-thru

The honest truth about fast food on keto is that portions and recipes vary, and a "low-carb" order can still surprise you. That's where CarbMeNot earns its place: snap a photo of your meal right there in the parking lot, and it estimates the net carbs and macros so you know where you stand before your next meal. No menu hunting, no guessing at sauce sugar — just point, log, and drive.
