The Best Keto Fast-Food Orders at 12 Top Chains

Don't stress about eating keto at fast-food restaurants! You have more options than you may realize.
FACT CHECKED BY Olivia Tarantino

Fast food might be tasty and convenient, but when you're also trying to adhere to a diet where success hinges on certain restrictions that limit your dining possibilities, these places may seem more like intimidating havens of temptation. This is especially true if you're on a keto diet, considering that French fries, crispy batters, and bread-based items like pizza or burgers are a hard "no" if your aim is to trigger ketosis and lose weight by converting your fat and protein stores into energy. While finding keto fast food may seem as impossible as searching for a needle in a pile of haystack onion rings, it's actually easier to place a keto-friendly fast food order than you may realize.

In fact, many fast-food chains have made the effort to diversify their menu options to accommodate most dietary preferences. This includes making menu options more customizable and being flexible with modifications to ensure your meal hits the right spot without throwing you off course with your goals. So, no need to stress over making substitutions, especially when you pull up to the drive-thru with a solid sense of the keto fast-food options that are available to you.

11 Best Low-Carb Fast-Food Orders, According to Dietitians

What does it mean to 'eat keto'?

A basic keto diet consists of low-carb, high-fat foods and drinks, and modest protein consumption. While historically used for epilepsy treatment in children, "[the keto diet has] become more popular since low-carb diets became a trend in the 1990s," according to registered dietitian Caroline Thomason, RD, LDN, CDCES.

The goal of the diet is to get into ketosis, a metabolic state where the body burns fat for energy instead of glucose.

"To get into ketosis, the macros consumed needs to be 70–75% of calories from fat, 20–25% of calories from protein, and 5–10% of calories from carbs," explains Toby Amidor, MS, RD, CDN, FAND, award-winning nutrition expert and Wall Street Journal bestselling author of The Family Immunity Cookbook.

"Some folks follow keto by counting net carbs which should be less than 35 grams per day. Net carbs are calculated by subtracting grams of fiber from total grams of carbs," Amidor adds.

What are some pros and cons of following a keto diet?

"The benefits of eating keto are similar to the benefits of other calorie-restricted eating plans," says Thomason. "For folks who enjoy eating in a low-carb diet pattern, they often report increased feelings of satisfaction and decreased feelings of hunger. This makes it easier for them to regulate their calorie consumption and lose weight over time."

That said, Thomason is also very candid about the potential drawbacks of following a strict keto diet.

"However, there's nothing magical about keto. It's simply another way to manage your calorie intake—and if it works for you, great! Largely, I see that it does not work for the majority of my clients. The reason is that they feel too restricted and crave the carbohydrates that they feel they are unable to eat. This can result in yo-yo dieting or periods of calorie restriction followed by periods of overindulging."

So while eating keto can be effective for some, it's not a "one-size-fits-all" dieting solution. If you know you're a carb craver and have a bad history with yo-yo dieting, don't self-sabotage and set yourself up for failure by trying to fit a square peg into a keto hole. Before going all in on eating keto, consult your healthcare provider to see if it's the best fit for you.

Tips for ordering keto fast-food anywhere

There are a few easy things to keep in mind when trying to identify keto-friendly fast food options, according to Amidor as well as Trista Best, MPH, RD, LD, a registered dietitian at Balance One Supplements:

  • Keep your order simple: "A piece of grilled chicken or salmon is usually a safe bet as is a bowl of steamed broccoli," suggests Amidor.
  • Remember that drinks count: "Stick to water, unsweetened iced tea, or black coffee instead of sugary sodas or shakes," recommends Best.
  • Ditch the buns: "Many fast food chains offer the option to order burgers without the bun," advises Best. "Simply ask for the burger patty, cheese, lettuce, and tomato, and skip the ketchup and other sauces."
  • Forget fried and go for grilled: "Avoid breaded or fried meats, and opt for grilled or roasted chicken, beef, or fish," says Best.
  • Swap out classic high-carb sides for keto-friendly alternatives: "Instead of fries, look for low-carb sides like side salads, broccoli, green beans, or a side of bacon," says Best.
  • Ask questions: "If you think ordering a burger without the bun is keto—it probably isn't," says Amidor. "Many fast food chains add flavors, fillers, or marinades to their food to help them taste better or bulk them up. These ingredients may contain carbs, which if eaten in too high amounts can make you not feel well or take you out of ketosis if eaten regularly. Always ask to see the nutrition info or ask to see an ingredient list," she advises.
  • When in doubt, check the nutrition info: "Many fast food chains have nutrition information available online or in-store. Check the carbohydrate and fat content of menu items to make informed choices," says Best. "If you're on the go, bring some keto-friendly snacks like nuts, cheese, or jerky to help you stay on track between meals."
  • Consider a modified keto diet: "Most folks are actually following a modified keto diet with less strict guidelines with 55% of calories from fat, 35% of calories from protein, and 15% of calories from carbs," explains Amidor. "This less strict plan allows more room for carbs and more room for nutrient-filled foods you may be missing out on if you're following a strict keto diet." This is also a great deterrent against the risk of falling into an unhealthy cycle of yo-yo dieting Thomason previously mentioned.

"Eating keto at fast food restaurants can be challenging, but it is possible with a little planning and careful menu selection," adds Best.

Still unsure of exactly how to narrow down fast-food menus to just the keto-friendly dining options? To help you with this planning, we've rounded up a list of some of the best keto fast-food menu items you can order. Next time you find yourself in line at your fave fast food joint, consider ordering any of these keto-friendly fast food picks.
