Share to save for later!

Staying keto at In-N-Out Burger is not all that hard. In fact, low-carb In-N-Out burgers are one of our top options if you just have to settle an odd fast food craving.

The chain might only be available to you if you live in certain parts of the country, but it has quickly become one of the most talked about fast food chains around.

If you’re on a low-carb or keto diet it’s a no-brainer that you’ll be skipping the bun and fries. In-N-Out makes this easy by offering a Double Protein Style burger. Your burger is served up wrapped in crispy lettuce instead of a bun. Perfect!

In-N-Out offers more ways to customize your burger in a keto-friendly way.

We’ll show you some tips and tell you how to order low carb at In-N-Out Burger so you don’t accidentally wreck your ketogenic diet the next time you wind up here.

A Word Of Caution About Fast Food

We can sum up all fast food restaurant meals in one sentence: don’t do it if you don’t have to.

In other words, don’t make In-N-Out Burger your first choice for food. Always prepare your ketogenic meals at home using high-quality, organic ingredients to ensure that you have total control over what (and how much) you’re eating.

Yes, you can get a low-carb meal or snack at In-N-Out Burger once in a while, but it’s not something you want to make a habit out of. The same goes for any other low carb fast food options.

In-N-Out Burger is a better option than most because they offer lettuce buns in place of regular buns, but you can still buy better quality meat at the grocery store, such as organic, grass-fed, and pasture raised, which is a cleaner source of protein. Be sure to save all fast food meals for emergency situations only.

How To Order Low Carb At In-N-Out Burger

In-N-Out Burger only has three different burger options on the menu. This means that you won’t be overwhelmed or intimidated by a large menu when you pull up to the drive-through.

The best way to make sure you get a low-carb meal at In-N-Out Burger is to order your burger without the bun or any sauce. You can ask for your burger to be wrapped in a lettuce wrap instead, or simply toss the bun when it comes and eat the insides only.

Ideally, you want to focus on eating the meat, cheese, and low-carb vegetables (such as lettuce) that come on the burger. We’ve broken down how to order each of the three burgers at In-N-Out Burger.


The Double-Double burger at In-N-Out is probably the most popular. It comes with a bun, two American cheese slices, two beef patties, fresh or grilled onions, lettuce, a sauce, and tomatoes. You can make this a low-carb burger by ordering it without the bun and sauce.

This is a great option because you won’t have to worry about being tempted to eat the bun if it accidentally comes with your burger.


The second burger option you have at In-N-Out is a cheeseburger, which comes with a bun, one American cheese slice, one beef patty, onions, lettuce, sauce and tomatoes. Again, you’ll want to hold the bun and sauce to keep it low-carb.

If one beef patty isn’t enough for you, you can always ask for double meat. Just be sure to ask for no sauce as they will probably add a layer in between each patty if you don’t specify.


The last burger you can order at In-N-Out Burger is an In-N-Out hamburger. It comes with everything a cheeseburger does, minus the slices of American cheese.

As always, order this without the bun and sauce. If you’re really hungry, you might want to get a cheeseburger instead as the fat from the cheese will help fill you up.

A hamburger would be a good option if you only need a snack to tide you over until your next meal. If you’re looking for something to sustain you for a few hours, then ask for double meat.

Easy Keto In-N-Out Ordering With the ‘Not So Secret Menu’

Although In-N-Out only has three burgers, they also offer a ‘Not So Secret Menu’ which allows you to customize your burger. Here’s what the extra menu offers and how to use it (and not use it) to keep your keto on.

Protein Style: Always order your burger ‘protein style’. This means you’ll get a lettuce-wrapped burger instead of a bun.

Flying Dutchman: While a ‘protein style’ burger comes with a lettuce wrap, the Flying Dutchman consists of only the two patties and two slices of cheese—no buns and no lettuce. Another great keto option.

Animal Style: If you order an ‘animal style’ burger you’ll get patties grilled with mustard, grilled onions instead of raw, extra spread, and extra pickles. We don’t recommend any animal style burgers on a keto diet since you’ll be adding 10g to 20g of carbs to your meal.

Double-Double or 2X2: With this order you’ll get a double In-N-Out cheeseburger. That means two slices of cheese and two patties.

Triple Triple or 3X3: Your burger comes with three slices of cheese and three patties.

Quad Quad 4X4: This cheeseburger has four slices of cheese and four patties.

Regardless of the option you choose, always ditch the spread and make sure you order ‘protein style’ burgers.

Last Minute Tips

Keep in mind that all burgers at In-N-Out Burger can be made into a combo. As tempting as it might sound, don’t do it. Combo meals come with a burger, fries, and a drink. None of these sides are keto-friendly. Stick with the bunless and sauceless burger and don’t make it a combo.

In-N-Out Burger also doesn’t offer a side salad like some other fast food restaurants do. You can always ask for extra lettuce on your burger to get more antioxidants, vitamins, and fiber out of your meal.

Lastly, you’ll want to stay away from the milkshakes and sweetened beverages at In-N-Out Burger as these foods are obviously not keto-friendly.

The website says that their French fries are cooked in sunflower oil, which is a healthier option than soybean oil, but it’s still too high in carbs for you to eat on the keto diet.

Stick with unsweetened iced tea, coffee, or a bottle of water to wash your burger down with.

In-N-Out Burger only offers three different burger options, so there won’t be much else on the menu to tempt you. Stay away from the fries, sweetened beverages, and milkshakes.

If you’re starving, you can ask for double, triple, or quadruple the meat on your burger. They also offer a ‘protein style’ burger, which means that they will wrap your burger in a lettuce wrap instead of a bun—the ideal low carb burger. We recommend you skip the spread.

Finally, just remember, the optimal way to follow a low carb eating plan is to cook your own meals with keto-friendly foods. Fast food is just for emergency situations when you can’t do anything better.
