What is the Best low-carb fast food? 15 options

When you’re eating low carb or doing a strict ketogenic diet, one of the biggest challenges is eating out. Most fast-food restaurants offer mainly high carb meals which are rich in trans fats and not very high in other nutrients.

Does this mean your keto meal plan is doomed once you have to eat out? Definitely not!

While this list may not be exhaustive, here a few guidelines to help you make the right food choices, especially if you feel unsure of your meal options.

Use a Nutrition Calculator

When you’re trying to stay in ketosis, it’s important to know your numbers. How many grams of carbs and how many grams of protein are you getting with your meal? And do they fit your goals?

Keying in your portions in a calculator is a quick way to find out if a meal is right for you or not.

Skip the Salad Dressing and Condiments

Be wary of sauces, salad dressings, and condiments.

 The first low carb fast food option that comes to mind when you’re eating out is usually a salad.

While salads by themselves aren’t bad, most salad dressings and condiments tend to be high in hidden carbs.

For example, traditional Dijon mustard has zero carbs but some mustard sauces can have more than 10 grams of sugar!

Another good example, ranch dressing may not be low carb depending on how it’s made. So unless it’s specifically a keto-friendly version, you’d be safer avoiding it altogether.

Skip the Main Carb Portion

Since most fast food meals are built around a large serving of carbs and some protein, you can simply ask for a version of the same meal without the carb. (Think bunless burgers or burrito bowls without the burrito shell).

You can replace the carb portion with a healthy fat alternative like guacamole to help boost satiety.

Deep-Fried Foods Can Be Tricky

A lot of fast-food chains offer deep-fried foods that have been coated with a batter, breaded or marinated with spices that maybe have hidden sugars.

To be on the safe side, stick with grilled, roasted or baked options when it comes to proteins like chicken. For example, opt for a grilled chicken salad over a spicy fried chicken with coleslaw.

Drink Lots of Water

If you’re really hard-pressed for satisfying options, just chug down some bottled water on top of your meal until you’re able to get home or find keto meals that work for you.

Water is the best 0g fat, 0g carb drink available and will fill you up quickly enough. 

Now that you have a general idea of how to select meals on the go, here are 15 low carb meals and keto-friendly fast food options to consider next time you’re pressed for time (and food).

Egg Based Keto Breakfasts

Eggs are a popular go-to keto breakfast option because they are versatile, easy to prepare and provide up to 6g of protein each. But if you’re short on time, you may not always have the chance to whip up a batch of your favorite deviled eggs or breakfast bacon egg muffins. These low carb egg breakfast options are worthy replacements!

McDonald’s Options

Looking to try a McDonald’s keto meal for your breakfast?  The fast-food giant recently began providing an all-day breakfast menu which has some great keto breakfast options. 

They also have an A-La-carte menu meaning you can pick your combo of choice e.g. sausages, egg and cheese and skip any high carb options. Better yet you can bring along your own keto cheese biscuits to complement your meal!

1. Egg McMuffin (minus the English muffin) – a combo of American cheese, Canadian bacon, and eggs which contains 2g net carbs, 11g fat, and 12g of protein and approximately 160 calories.
