How to Order Low Carb Options at Jack in the Box For Keto Diet

Among all the American fast-food restaurants, you'll have higher chances of enjoying low-carb keto options at Jack in the Box.

This is because they have an extensive menu from pasta to burgers to sandwiches and many more. The dishes that they offer range from carbohydrate-rich to low-carb options.

Another great thing about their menu is you can find a way to turn their regular dishes into low-carb options. Here are some tips on how to do that:

If you want to order a sandwich, hold the bun and sauce.

Sandwiches are some of the biggest hits in Jack in the Box, but as you may already know by now, bread is a big no-no. The good news is you have the option to ditch the bread.

If you feel that the sandwich will not be as filling without the bread, you'll be happy to know that most of their sandwiches are loaded with generous amounts of meat, eggs, and cheese.

They are sure to fill you up, but also unhealthy for your diet. Therefore, your solution is to add more meat to make it more satisfying.

Additionally, most of the sandwiches come with sauces. These sauces contain sugar and may be rich in carbohydrates, so you should ask them to hold the sauces too.

Order a bunless burger and order a salad on the side.

From its name, these are burgers with no buns, so you'll mainly get a burger patty, Cheese, veggies, and other toppings.

Ask them to hold the fries or onion rings that usually come with it. Instead, order a side salad so you won't just lower your carbs intake but boost your fiber consumption as well.

Choose hard shell over soft shell tacos.

While both shells contain carbohydrates, we recommended choosing the hard shell tacos.

They are easier to eat than the fillings of a quesadilla or soft shell tacos.

Go for unsweetened drinks.

Since you're eating at a fast-food restaurant, most of the drink offerings you can choose from have high sugar content.

It would be best that you stick with water but if you want something more refreshing, go for unsweetened teas.

Always check the nutrition facts.

We love this fast food restaurant because they provide their customers with all their dishes' nutrition facts. (1) 

With this, you can check the macros of the meal that you're planning to get to ensure that it will fit your low-carb diet.

If the dish comes with sauce, don't forget to hold the sauce. The good thing is the chicken strips are already flavorful in itself, so you won't need the dipping sauce to boost its taste.
