Keto Fast Food: 20 Chains Ranked by Best Low-Carb Order
The single best low-carb fast-food order across 20 major chains is plain, unsauced chicken wings — Wingstop's traditional wings run about 0g net carbs. For a full meal you can order without any special requests, Chick-fil-A's Grilled Nuggets (12-count) at 2g net carbs is the most reliably keto option at any drive-thru in the country.

You don't need to skip the drive-thru on keto — you need to know which chains make it easy and which ones bury carbs in sauce, breading, and rice. This roundup ranks 20 major U.S. chains by the net carbs in their best available order, plus the one swap that makes each one work. Seven of these chains have a full ordering guide with every menu item broken down — links are below each entry.
What are the 20 best keto fast-food chains, ranked by net carbs?
Wingstop, Domino's, and KFC top this list because plain or breading-removed chicken carries almost no carbs on its own — the carb count comes entirely from sauce, breading, and sides you can decline. Chains near the bottom, like Chipotle and Burger King, still work on keto; their "best order" simply has a few more grams from spread, guacamole, or grilled onions.

Net carbs above are estimated from published nutrition data for the order as described (no bun, no rice, sauce as noted) and rounded to the nearest gram.1 Confirm exact numbers for your location with the net-carb calculator and the chain's own nutrition page before you rely on them for strict/therapeutic keto.
1. Wingstop
Order the classic bone-in wings plain or dry-rubbed and skip anything glazed or breaded — Wingstop's traditional wings run about 0g net carbs, the lowest order on this whole list.2
2. Domino's
Skip the pizza and the discontinued cauliflower crust and order a tray of plain bone-in wings instead, about 1g net carbs; avoid the BBQ, honey BBQ, and sweet Asian glazes, which add sugar fast.
3. KFC
Original Recipe and Extra Crispy are both breaded, so ask for a grilled option where it's on the local menu, or eat the meat and leave the breading — either way lands around 1g net carbs.
4. Chick-fil-A
Grilled Nuggets are the most consistently keto order in fast food: no breading, no bun, about 2g net carbs, and they hold up well for later. See our full Chick-fil-A keto guide for the whole menu ranked.
5. Popeyes
The menu leans fried, but blackened tenders (where available) or a piece of fried chicken with the breading removed both land around 2g net carbs; skip the red beans and rice and mashed potatoes sides.
6. Dunkin'
Order any egg-and-cheese sandwich without the English muffin, croissant, or wrap, and skip the hash browns — a Sausage Egg & Cheese eaten bread-free runs about 5g net carbs. See our full Dunkin' keto guide for drinks and food.
7. Culver's
Ask for any ButterBurger "in a lettuce wrap" instead of a bun and hold the ketchup, and you land around 6g net carbs; the fried cheese curds and crinkle fries are the carb traps to skip.
8. Five Guys
Request a Bacon Cheeseburger wrapped in lettuce instead of a bun — about 6g net carbs — and stick to the free toppings bar for grilled onions and jalapeños rather than the ketchup.
9. Jimmy John's
The Unwich swaps the bread for a lettuce wrap on any sandwich; a Turkey Tom or Italian Night Club Unwich runs about 7g net carbs — skip the au jus and vinaigrette dressings, which carry added sugar.
10. Whataburger
Order any burger "in a lettuce bun" instead of a bread bun; a plain Whataburger this way lands around 8g net carbs, and the grilled chicken sandwich works the same way.
11. McDonald's
Ask for a Quarter Pounder with Cheese with no bun for about 9g net carbs; the special sauce and ketchup carry sugar, so stick to mustard or mayo. See our full McDonald's keto guide for every low-carb order.
12. Sonic
Any Sonic burger ordered without the bun runs about 9g net carbs; skip the tots and the cherry limeade, and ask for unsweetened iced tea instead.
13. Subway
Turn any Subway Series sandwich into a chopped salad — same protein and toppings, no bread — for about 9g net carbs; avoid the sweet onion and honey mustard dressings. See our full Subway keto guide for salad and bowl builds.
14. Taco Bell
Order a Power Menu Bowl and ask them to hold the rice and beans, doubling the lettuce and cheese instead, for about 9g net carbs; skip the tortilla strips and any red sauce packet with added sugar. See our full Taco Bell keto guide for the whole menu.
15. Panda Express
Swap the rice or chow mein for SuperGreens and order a grilled protein like Teriyaki Chicken with the sauce on the side, about 9g net carbs; the Orange Chicken and Honey Walnut Shrimp are both breaded and sugar-glazed, so skip them.
16. Jersey Mike's
Ask for any sub "in a tub" — a salad bowl instead of bread; a Big Kahuna Chicken Cheese Steak in a tub runs about 9g net carbs — hold the sweet onion or honey mustard dressing.
17. Wendy's
Order a Baconator without the bun and skip the ketchup for about 10g net carbs; a side salad with ranch is a better swap than fries. See our full Wendy's keto guide for every low-carb order.
18. Chipotle
Build a salad bowl with a protein, fajita veggies, cheese, and guacamole, and skip the rice, beans, corn salsa, and tortilla — about 11g net carbs. See our full Chipotle keto guide for a step-by-step bowl build.
19. In-N-Out
Order "Protein Style," where the burger is wrapped in lettuce instead of a bun; a Double-Double this way runs about 11g net carbs, mostly from the spread and grilled onions — ask for it without spread to cut a few more grams.
20. Burger King
A Whopper without the bun runs about 11g net carbs, mostly from the ketchup and onions; ask for mayo only, or try a Bacon King without the bun for a leaner option.
How were these fast-food chains ranked for keto?
Chains are ranked by the net carbs in their single best available order, then by how easy that order is to get without special requests. A chain with a naturally low-carb protein (wings, grilled chicken) ranks above one where you have to remove bread, rice, or a sugary sauce to get there, even if the final numbers are close.
Three factors decide rank:
- Net carbs in the best order — the biggest factor, using the chain's own published nutrition data where the substitution (no bun, no rice, sauce omitted) is applied.
- Menu flexibility — can you get a lettuce wrap, a bowl instead of a sandwich, or breading removed without a fight at the counter?
- Hidden carbs — how much of the default order's carb count is buried in sauce, glaze, breading, or a "healthy-sounding" side (teriyaki, honey mustard, sweet chili all carry sugar).
What swaps work at any fast-food drive-thru on keto?
Five swaps work at almost every chain on this list: skip the bun, bread, tortilla, or wrap; ask for a lettuce wrap or a bowl instead of a sandwich; swap fries or rice for a side salad or extra vegetable; hold or sub the sauce (mayo and mustard are safer than anything sweet or red); and order unsweetened tea, black coffee, or water instead of soda or a "diet"/flavored drink you haven't checked.
Two more habits keep you under budget without slowing down the line:
- Say "no bun/no rice, extra veggie" as one sentence — most counter staff have heard it and won't need it repeated.
- Ask for sauce on the side. Even a keto-safe sauce like ranch adds up fast if it's poured over the whole order instead of dipped.

What's a sample keto fast-food order under 20g net carbs?
Any single order from the table above already lands under 12g net carbs, which leaves room to add a side and still stay well under 20g for the meal. A few combinations that work:
- Chick-fil-A Grilled Nuggets (12-ct) + a side salad with avocado lime ranch — about 9g net carbs
- McDonald's Quarter Pounder with Cheese, no bun + a side salad, no croutons — about 15g net carbs
- Chipotle chicken salad bowl with extra fajita veggies and guacamole — about 11g net carbs
- Taco Bell Power Menu Bowl, no rice or beans, plus a side of guacamole — about 12g net carbs
Run any combination through the net-carb calculator to fit it into your own daily total.
