Share to save for later!

Jack In The Box is a fast food restaurant chain located mostly on the west coast near California. They also have locations in Arizona, Colorado,  Texas, Tennessee, Missouri, Indianapolis, and Ohio.

Although they have a lot of fried foods on their menu, Jack In The Box is a decent place to get a low-carb meal when you’ve forgotten your lunch at home. We don’t recommend eating fast food often (if at all). However, if you’re in a jam, then you can do a lot worse than Jack In The Box for a meal once a month or so.

We like that Jack In The Box offers lots of burgers, chicken, and salad dishes, which are easy to customize into low-carb dishes. They also serve breakfast all day, which is great for grabbing a bunless sausage, egg, and cheese sandwich. They even offer delivery if you’re stuck at work and need something brought to you.

Like every fast food chain, there are plenty of foods on the menu that you’ll need to avoid. We’re here to help you make a smart low-carb choice. Just follow these tips and suggestions.

Tips For Ordering at Jack In The Box

Jack In The Box is much better than other fast food chain restaurants at providing decent opportunities to turn your food into a low-carb meal. It’s a much better place to eat than say a pizza restaurant or a fried chicken place.

They have salads, sandwiches, burgers, and even breakfast. But keep in mind that eating at home or at least preparing your foods with store-bought keto-friendly ingredients is always best.


Most fast food restaurants try to focus on keeping the cost of their food down, which means that they usually use cheaper ingredients than you would if you were to cook at home.

You might be able to get a burger for about half the price that it would take you to make it at home, but your meat won’t be high quality, organic or grass-fed.

The best thing you can do is dedicate one day a week to meal prepping at home. Cook up all your meats and store them in containers. Then purchase organic, low-carb vegetables to go with them, such as lettuce wraps, cruciferous vegetables, and leafy greens.

If your budget allows, buy organic, pasture-raised eggs, cheese from grass-fed cows, and pork and bacon that’s antibiotic and nitrate free. It only takes a few minutes to section off your meals for the week and you’ll have them when you need them.

If you accidentally leave a meal at home, then Jack In The Box can be a good stand-in, but we don’t recommend making a habit out of eating fast food. We recommend looking at the menu before you go so that you can make an educated choice.

Lowest Carb Meals

Here are our top choices for lowest carb meals at Jack In The Box according to the nutrition information:

  • Chicken club salad with grilled chicken (7 grams net carbs)
  • Grilled chicken salad (8 grams net carbs)
  • Bacon, egg and cheese biscuit (hold the biscuit)
  • Bacon and egg chicken sandwich (if available; hold the bun and sauce)

You can find all of the nutritional information on the Jack In The Box website, which is a good way to track your macronutrients if you need to stay under 20 grams for the day.

We also like that Jack In The Box lists all the ingredients in their food. You can take a look at their menu on their website. 

According to the ingredients menu, the bacon and beef patties bone contain sugar. Also, the beef steak strips contain vegetable oil and Carrageenan, which is a food additive that has been shown to cause digestive upset. 

The grilled chicken also contains sugar, preservatives and vegetable oil. Even the eggs are fried in butter flavored vegetable oil. 

This is why we always recommend that you purchase high quality meats at the supermarket or at your local butcher instead of eating out. 

Here are some tips to help you keep it low-carb.

#1. Get a breakfast sandwich and hold the bun

Jack In The Box offers breakfast anytime of the day. Breakfast sandwiches are a good way to eat low-carb because they often feature meat, cheese, and eggs. You just have to remember to ask them to hold the bread or toss it as soon as it comes. Breakfast sandwiches are also less likely to have sauce on them like a regular sandwich or burger would.

You can check out the breakfast menu at Jack In The Box here. Stay away from the hashbrowns, pancakes, and burritos, which are hard to eat the insides only out of. Stick with a croissant, sandwich, or biscuit instead because it’s easier to toss the bread. It doesn’t look like Jack In The Box offers freshly brewed coffee, but you can get unsweetened iced tea to meet your caffeine needs.

#2. Order a side salad with your bunless burger

Jack In The Box offers a nice selection of burgers and salads. Pair them together and you have a great low-carb meal. Choose from one of their many burgers and ask to hold the bun and any sauce that comes on it.

Then, ask for a side salad made without any dressing instead of fries or onion rings. You can ask if they have oil and vinegar as a dressing option, but most fast food places don’t. So, you’ll likely have to eat your salad plain. Be sure to hold the croutons, too.

#3. Avoid the combo meals

Lots of fast food restaurants offer different types of meals on their menu. It’s a good way to get a lot of food for not a lot of money.

Unfortunately, you can’t eat any of the stuff that comes with a meal, such as fries, onion rings, tacos, and a drink. You could always eat the insides only out of a taco. But Jack In The Box offers lots of other low-carb options so you shouldn’t need to resort to this.

We recommend sticking with a single burger, sandwich or salad, and don’t try to make a combo meal out of it. If you choose to order a meal, make sure you hold the bun and sauce on your burger as well as any sauce that comes on the taco. If given a choice, then pick a hard shell taco over a soft shell as these are easier to eat the insides only out of. Also, hold the fries and choose an unsweetened iced tea as your beverage of choice.

It’s always best to buy high-quality meats and cheeses from the grocery store and prepare them at home with low-carb veggies. But if you’re in a pinch and need food quick, then order a bunless and sauceless burger at Jack In The Box with a side salad in place of fries as a low-carb meal.

Just be sure to toss the bun and be cautious of any sauce that comes on it. They have a good selection of salads, too. We recommend going with a grilled chicken salad or even eating the insides out of a taco. Or try one of their pannidos and tossing the bread for a filling low-carb meal. Stick with a single meal and avoid trying to make a combo meal work. You’ll only end up throwing away a bunch of food that you can’t eat.
