How to Build a Keto Meal at Five Guys

Five Guys' menu is packed with keto-friendly picks, so your options for creating a satisfying meal are vast. Here's exactly what you need to do to order a perfectly keto meal at Five Guys every single time:

Step 1 - Pick Your Protein Base

As simple as this is, there are a few mini-steps to consider:

1. Hamburger or Hot Dog

Your first choice is between two American classics: a hamburger or a hot dog.

The hamburger is a 3.3 oz fresh ground beef patty, and the hot dogs are Hebrew National beef franks.

2. Little or Regular

If you choose a hamburger, you'll then need to decide if you want to order a Little Hamburger or a Hamburger. The Little Hamburger has just one 3.3 oz patty, whereas the regular Hamburger has two patties for a total of 6.6 oz of beef.

3. Cheese, Bacon, or Both

Once you've made this key decision, you'll have one more critical decision to make, and that is, do you want cheese on that, bacon, or both?

The good news is that you can't go wrong with any of these selections because they're all as keto-friendly as it gets!

But, to help you make your choice a little easier, here are the approximate macronutrients for each:

Hamburger

  • Macros: 440 calories, 34g fat, 0g net carbs, 32g protein

Cheeseburger

  • Macros: 482 calories, 35g fat, 0g net carbs, 40g protein

Bacon Burger

  • Macros: 520 calories, 41g fat, 0g net carbs, 36g protein

Bacon Cheeseburger

Step 2 - Make it Bunless

This is key to making your Five Guys meal keto-friendly. With a whopping 37 grams of net carbs per bun, chowing down on a bun will kick you out of ketosis.

Instead, request a lettuce wrap or just keep it simple and go without!

Pro tip: If ordering a lettuce wrap, ask for a "double lettuce wrap." This extra lettuce will provide a more structurally sound wrapping and better contain your toppings.

Step 3 - Add Keto-Friendly Toppings

In addition to being free, the other good news about Five Guys' toppings is that most of them are keto-friendly!

In fact, there are just two toppings to avoid: the Bar-B-Q Sauce, which clocks in at 15 grams of net carbs per serving, and the ketchup, which contains 5 grams of net carbs per serving.

Here are the macros for each keto-friendly topping you can choose from:

A.1 Sauce

  • Macros: 15 calories, 0g fat, 3g net carbs, 0g protein

Green Peppers

  • Macros: 5 calories, 0g fat, <1g net carbs, 0g protein

Grilled Mushrooms

  • Macros: 5 calories, 0g fat, 1g net carbs, 0g protein

Hot Sauce

  • Macros: 0 calories, 0g fat, 0g net carbs, 0g protein

Jalapeño Peppers

  • Macros: 3 calories, 0g fat, <1g net carbs, 0g protein

    Lettuce

    • Macros: 4 calories, 0g fat, <1g net carbs, 0g protein

    Mayonnaise

    Pickles

    • Macros: 3 calories, 0g fat, 1g net carbs, 0g protein

    Tomatoes

    • Macros: 9 calories, 0g fat, <2g net carbs, <1g protein

    Step 4 - Swap the Fries for Peanuts

    As you may have guessed, fries are loaded with carbs so they're a no-no on the keto diet.

    Even the smallest size, a Little Fry, will set you back 64 net grams of carbs, which is enough to kick even the most experienced keto dieter out of ketosis.

    Instead, help yourself to a serving of complimentary peanuts. A serving, which is approximately 28 shelled peanuts, delivers 166 calories, 14g of fat, 4g net carbs, and almost 7 grams of protein, making it a nutritious addition to your meal.

    Step 5 - Keep Your Drink Simple

    Save the milkshakes and sodas until you're done with the keto diet, and instead, keep it simple with unsweetened iced tea or water.

    Dasani Bottled Water

    • Macros: 0 calories, 0g fat, 0g net carbs, 0g protein

    Gold Peak Unsweetened Iced Tea

    • Macros: 0 calories, 0g fat, 0g net carbs, 0g protein

    Yes — by choosing burgers without buns (lettuce wrap or bowl), selecting low-carb toppings, and skipping high-carb sides and drinks.

    How many carbs are in a Five Guys bun?
    The bun has about 37 g net carbs, so removing it is a major keto win. 

    Which toppings at Five Guys are keto-friendly?
    Great options include mustard, mayo, lettuce, pickles, grilled mushrooms, green peppers, onions, and jalapeños. Avoid ketchup, BBQ sauce, and relish, which add extra carbs. 

    What to do instead of ordering fries?

    Is ordering a burger “in a bowl” or “lettuce-wrapped” actually low-carb?

    Are Five Guys' hot dogs keto-friendly?
    They can be — a Hebrew National beef hot dog has very low carbs, but you’ll need to skip the bun or ask for it in a bowl or lettuce wrap.
