Keto Fast Food
Last updated June 10, 2026 · Reviewed by Jordan Lee, Nutrition Editor
Yes, you can eat keto at almost any drive-thru — the trick is ordering the protein and skipping the carbs around it. Ask for any burger or sandwich "bunless" (most chains wrap it in lettuce), drop the fries, breading, tortillas, and croutons, and your meal lands close to zero net carbs. Net carbs = total carbs minus fiber and sugar alcohols, and a typical keto target is 20–50g net carbs per day, so the buns and fries are usually what blow your budget, not the meat or cheese.
The two stealth carb sources at fast food are sauces and drinks. Ketchup, BBQ, honey mustard, teriyaki, and most "special" sauces are sugar-loaded; mayo, ranch, mustard, and butter are safe. Swap soda and sweet tea for water, diet soda, or unsweetened iced tea or coffee. Order plain grilled (not crispy) proteins and you'll stay on track at burger joints, taco spots, chicken chains, and coffee shops alike.

Tips
- Order any burger or sandwich 'bunless' or 'protein style' — most chains will wrap it in lettuce at no charge
- Choose grilled over crispy or breaded; breading can add 15–30g net carbs to otherwise-keto chicken
- Default to water, diet soda, or unsweetened iced tea/coffee — a regular soda can carry 40g+ carbs on its own
- Skip ketchup, BBQ, honey mustard, and teriyaki; reach for mayo, ranch, mustard, butter, or sugar-free hot sauce
- At taco and burrito spots, order a bowl or salad with no rice, beans, tortilla, or chips and add extra meat, cheese, and guac
- Build sides from the cold case — side salad, bacon, eggs, or cheese — instead of fries, hash browns, or biscuits

Frequently asked questions
- What fast food can I eat on keto?
- Bunless burgers, grilled (not breaded) chicken, plain bacon and eggs, taco-bowl meats without rice or beans, and side salads all work. Focus on the protein, cut the bun, fries, breading, and tortilla, and pick low-carb sauces like mayo, ranch, or mustard.
- Are french fries keto?
- No. A medium order of fries runs roughly 40–50g net carbs — about a full day's keto allowance. Swap them for a side salad, bacon, eggs, or extra protein instead.
- Can I have a bunless burger at the drive-thru?
- Yes, and it's the single best keto fast-food move. Order it 'bunless,' 'protein style,' or 'lettuce wrapped' and a typical cheeseburger drops to around 1–3g net carbs. Add bacon, cheese, and mayo freely.
- What can I drink at fast food on keto?
- Water, diet soda, unsweetened iced tea, black coffee, or coffee with heavy cream and a sugar-free syrup. Avoid regular soda, sweet tea, lemonade, juice, frappés, and most flavored or 'lite' drinks, which are loaded with sugar.
