Low-Carb Lunch Entree Test

These choices were made based on what entrees the fast food is most prominent in their promotions. 

Bunless Bacon & Swiss Buttery Jack

The Buttery Jack is Jack in the Box’s specialty burger. The Bunless Bacon & Swiss Buttery Jack has a quarter-pounder beef patty, bacon, Swiss cheese, garlic herb butter, and bacon mayo. 

This bunless burger stands out because of the unique flavor combination of the garlic herb butter and bacon mayo. It may be an acquired taste for some, but it is quite enjoyable once your palate adjusts to it. You may also want to order a double patty as the “quarter-pound” patty may seem too small to be filling. 

  • Price: $5.19
  • Nutrition: 690 calories and 0 net carbs
  • Taste:  Average.
  • Food highlight: The grilled patty was tender, juicy, and firm – firmer than Mickey D’s low-carb burger. The bacon was not fried to a dry crisp, although if this is what you prefer, you can request for it. 

Bunless Double Jack

Although bunless, double cheeseburgers are usually filling and offer good value for your money. The Bunless Double Jack is a keto-friendly and delicious option – it tastes as great as it looks! Or it might taste better than it looks, depending on the server’s mood. This was the most tasteful among the three lunch entrees listed on this review. 

  • Price: $5.49
  • Nutrition: 660 calories and 2 net carbs
  • Taste: More than above average. 
  • Food highlight: The No-bun Double Jack was an immensely satisfying low-carb entree. The patties were grilled just right, and the veggies were crisp and fresh. 

Grilled Chicken Club Salad

This is a common low-carb entree in most fast food restaurants and, as a salad, it’s expectedly light – in satiety factor, calories, and flavor. But Jack in the Box’s Grilled Chicken Club Salad has bacon and ranch dressing, which makes it more satisfying. Of course, you have to take note of the added calories. 

  • Price: $6.19
  • Nutrition: 360 calories and 8 net carbs
  • Taste: Above average. 
  • Food highlight: The chicken was tender and full of flavor. The veggies were crisp and fresh. You can eat it sans the bacon and substitute Italian dressing for the ranch and it will still taste great but with fewer calories. This is definitely a must-try!

Low-Carb Breakfast Entree Test

Bunless Extreme Sausage Sandwich

The “Extreme” in this bunless sausage breakfast sandwich refers to the two sausage patties. It also has American cheese and a fried egg patty. It’s a classic sandwich that delivers in satisfaction. 

  • Price: $3.29
  • Nutrition: About 490 calories and 0 net carbs.
  • Taste: Beyond above average.
  • Food highlight: This was a no-frills, no-mess, and filling sandwich even without the buns. A highly recommended keto breakfast that is comparable to Mickey D’s low-carb breakfast options. 

Bunless Loaded Breakfast Sandwich

A low-carb and filling option packed with a variety of meats, including bacon, ham, and sausage, plus fried egg and American cheese. 

  • Price: $3.69
  • Nutrition: About 540 calories and 4 net carbs.
  • Taste: Above average.
  • Food highlight: Satisfying to the palate and the stomach, but not better than the Extreme Sausage Sandwich. 

No-Tortilla Meat Lovers Breakfast Burrito

Almost the same as the Loaded Breakfast Sandwich, with bacon, ham, and sausage; but it has scrambled eggs instead of the fried egg patty, plus pepper jack and cheddar cheese. 

  • Price: $3.39
  • Nutrition: About 490 calories and 1 net carb
  • Taste: Average.
  • Food highlight: A hearty enough breakfast, but not the best among the three breakfast entrees. But if you like the combination of meats and two different cheeses, then this can be an enjoyable low-carb “burrito” meal for you. 


The Bunless Double Jack Cheeseburger is the best low-carb option for lunch or dinner, with around 660 calories and 2 net carbs and for its no-mess tastiness. The Extreme Sausage Sandwich should be your top pick for a low-carb breakfast, with only about 490 calories and zero net carbs. 

You can also choose from Jack in the Box’s other low-carb/keto offerings, which include 2 kinds of chicken sandwiches, 11 different burgers, and around 20 breakfast entrees that you can easily modify and turn keto.
