Which fast food restaurants you can eat at and still maintain a keto diet.

A keto diet is one of the most popular diets if you want to lose weight fast, and be able to see the results quickly. But following a keto diet is by no means easy. Especially if you live a busy and stress-filled lifestyle.

If your lifestyle is like this, then you might find yourself struggling to keep on track with your diet, especially if you prepare all your meals yourself.

Likewise, you could simply find yourself growing bored with having to prepare your meals, bored with eating the same food day in and day out, and bored with missing out on the delicious fast food that your friends are enjoying.

There are actually quite a few different fast food restaurants that offer keto-friendly options on their main menu. So, if you want to find out where you can get these, keep on reading. 

What Makes Fast Food Keto-Friendly?

Before we take a look at the best fast food restaurants to visit if you want to eat keto-friendly food, let’s take a look at what makes fast food keto-friendly. That is simple, for fast food to be considered keto-friendly, it has to be low in carbs and high in protein and fat.

The majority of diets focus on you eating a balanced diet, but a keto diet is not a normal diet. A keto diet recognizes that eating too many carbs is not good for you, and so this food category is limited.

A lot of people think that fats and proteins are bad for you, but this isn’t necessarily the case. It is all about planning your diet carefully, and a keto diet is definitely planned with care. 

Most of the time, eating a keto-friendly diet in a fast food restaurant will include modifying the regular meals that they have on offer. This is because a lot of fast food meals are heavy in carbs, and as we have said, this is something that is limited in a keto-friendly diet. With that in mind, let’s take a look at some of the best restaurants to visit if you are on a keto diet. 

Best Keto Fast Food Restaurants

  1. In-N-Out
  2. Chipotle
  3. Jack in the Box
  4. Burger King
  5. Taco Bell
  6. Wendy’s
  7. Five Guys
  8. McDonald’s
  9. KFC
  10. Arby’s


Up first, we have In-n-Out. In-n-Out is one of the best fast food restaurants to visit if you are following a keto-friendly diet, and that is because ordering keto-friendly food at In-n-Out is simple. In other restaurants, you will have to go through the individual ingredients of a meal, and ask for all the ingredients which aren’t suitable for a keto diet to be removed. 

But, if you are visiting In-n-Out, you simply have to order any item on the menu “protein-style”. This is a common order at the restaurant, and the restaurant will modify your meal accordingly. This will include replacing the bun with a lettuce wrap, and removing any ingredients that aren’t suitable for this diet. So, In-n-Out is one of the best places to visit if you are on a keto diet. 


Another great fast food joint to make a trip to when you are following a keto diet is Chipotle. Chipotle is a great choice because you design your own meal, so you can simply not order any menu items that aren’t suitable for your diet. 

On a keto diet, a burrito will not be suitable because it is a carbohydrate. But, the burrito bowl is perfectly fine for a keto-diet because this option skips the carb exterior. Pack your burrito bowl with proteins and greens, and you are guaranteed to enjoy it. One of the hardest parts when you are following a diet is giving up control, but at Chipotle you don’t need to do this, which is why it’s such a great place to visit. 

Jack in the Box

If you want to get yourself a good burger, then look no further than Jack in the Box. Of course, you won’t be able to have a bun with your burger if you are following a keto-diet, but Jack in the Box has found a way around this. This way is bunless burgers. 

Jack in the Box has a vast menu when it comes to burgers, so this means that you have a wide range of options to choose from. Whether you want a chicken burger, a hamburger, or a breakfast sandwich, Jack in the Box offers a huge range of bunless burgers, and that is why they are such a great place to visit. So, if you fancy a burger that won’t damage your keto-diet, head on down to Jack in the Box. 

Burger King

Alternatively, if you aren’t a big fan of the burgers at Jack in the Box, then you can get a variety of keto-friendly burgers down at Burger King. Of course, to order these burgers, you will need to modify existing options, and a lot of the time, this means removing the best bits. 

One of the best burgers to make keto-friendly at Burger King is their classic ‘Whopper’. Thankfully, the Whopper is full of enough flavor that this doesn’t get lost when you order it without its best bits.

By the best bits, we clearly mean the bun and the tomato sauce. When you remove this, something special is lost from the Whopper, but it still makes an excellent treat if you want to switch up your keto diet. 

Taco Bell 

Another place which is outstanding if you are following a keto diet is Taco Bell. Taco Bell specializes in options, and because of this, it is incredibly easy to modify your order to suit your diet. A lot of their menu options also do not require much modification to make them keto-friendly. 

If you want a delicious keto meal from Taco Bell, you should opt for the veggie power menu bowl. This bowl meal can be easily modified to remove the rice (which isn’t keto-friendly) with lettuce and guacamole to make it healthier and better suited to your diet.

The veggie power menu bowl is a great choice because it is full of flavor, and it tastes so good that you will forget that you are even following a keto diet. That’s what fast food is for, right?


Wendy’s is also the perfect place to visit if you are on a keto diet. This restaurant is great because they offer food that is specifically designed for those on a keto diet. This includes a range of keto salads, but by far the best item on their menu that is suitable for this diet is the Baconator. 

The Baconator is a firm favorite among fans of Wendy’s, and it is an excellent choice if you are following a keto diet too. You will have to remove the bun and the ketchup from this burger, but with these out of the way, you still have access to the best ingredients in the burger.

With 6 strips of bacon and a yummy cheeseburger, this option will taste so good that you will forget all about the missing bun and ketchup. So, if you are visiting Wendy’s, and are on a keto diet, the Baconator is the item to order.  

Five Guys

Speaking of burgers, Five Guys is another great place to visit if you are on a keto diet. Just like Chipotle, Five Guys allows you to design your own meal. So, you can simply design a burger that doesn’t contain any carbohydrates to make a keto-friendly burger. 

While Five Guys does not offer a carbohydrate-free alternative to the bun, they do deliver burgers that are ordered without a bun in a tray. This makes eating your bun-free burger a lot easier. You can simply order your burger, add whatever keto-friendly toppings that you want on top, then get stuck in with a knife and fork and enjoy! 


There are lots of items at McDonald’s which are keto-friendly, you simply have to make the modifications yourself. Just like Burger King and Jack in the Box, you can easily adapt your meal to ensure that it suits your diet. 

On the main menu at McDonald’s, the majority of the keto-friendly options do consist of cheeseburgers. But, there are salads and chicken sandwiches which can be modified to be keto-friendly too. As well as this, the majority of the breakfast options can be made keto-friendly by removing the bun.

So, while McDonald’s might not be the best choice for those on a keto diet, there are actually quite a few options to choose from. But, most of them will include removing the bun from your meal. 


If you are in the mood for chicken, then you have probably considered heading on down to KFC. A lot of the chicken on the menu at KFC is breaded, and these options will not be keto-friendly. But, thankfully, KFC offers another type of chicken which is. 

If you are on a keto diet, and you visit KFC, then you should avoid all the breaded chicken options, and instead choose the Kentucky grilled chicken. A lot of people don’t speak about this option, and that is simply because the fried chicken at KFC is so good. But, if you still want the flavor of KFC, without messing up your diet, this is the best option to order. 


Finally, let’s wrap this up with Arby’s. Even though Arby’s specializes in sandwiches, they are still a great place to visit if you are on a keto diet, and that’s because they are all pretty healthy. 

Of course, the bun that houses the sandwich will not be keto friendly, but almost all the fillings inside are. So, as long as you order your sandwich without the bun, this will be a keto-friendly meal. This might come as a surprise to a lot of people, because you might have immediately assumed that a sandwich shop will not be keto-friendly. But as we have said, with a few small modifications, this meal will be suitable for you if you are on a keto diet.
