The ketogenic, or keto, diet is highly restrictive, which can sometimes make eating out difficult. However, making small changes to many popular menu items can create keto friendly fast food.

A keto diet aims to put the body into a metabolic state called ketosis.

People following a keto diet typically eat high fats, moderate proteins, and very low carbohydrates. On a 2,000 calorie per day diet, carbs would amount to no more than 20–50 grams (g).

Often, fast foods contain added sugars and a high amount of carbs. So, to remain in ketosis, people following a keto diet need to choose keto friendly fast food wisely.

There are different variations of the keto diet. Some fast food choices contain higher amounts of protein than some keto diets allow.

However, people have different protein and energy requirements according to their weight, sex, and activity levels. Someone may want to adapt their fast food choices according to their needs.

This article looks at some popular keto friendly fast food choices and details their macronutrients and calories. It also discusses which foods and ingredients to avoid and some alternatives to order.

There are some ingredients and fast foods that people following a keto diet may wish to avoid.

These foods tend to be high in sugar or carbs. They include:

  • breads, including burger buns, muffins, and wraps
  • fries and hash browns
  • biscuits
  • ketchup
  • salad croutons
  • certain sauces, such as barbecue, teriyaki, and honey and mustard dressing
  • rice and noodles

The following tips can help someone enjoy their fast food meal while staying in ketosis:

  • Ask to swap high sugar sauces for high fat condiments, such as mayonnaise or olive oil.
  • Choose full fat salad dressings, but be sure to check the sugar content.
  • Request a side salad instead of a burger bun.
  • Add some extra avocado to a burger or chicken salad.
  • Ask for some extra cheese or cheese slices instead of buns or other forms of bread.
  • Choose a bowl rather than a taco or wrap.
  • Use lettuce leaves as substitutes for buns.

For quick snacks, people can also eat whole foods that are quick and convenient to prepare or buy from a grocery store.

Some keto friendly ideas include:

  • jerky
  • boiled eggs with mayonnaise
  • olives
  • avocado
  • cheese
  • nuts
  • celery paired with dips or dressings made with cream cheese or sour cream and mayonnaise

Fast foods based on meat and cheese can be suitable for people following a keto diet if they omit high carb ingredients, such as breads, noodles, rice, and sweetened sauces.

Many fast food restaurants allow people to design their meals to their requirements and provide detailed nutritional information.

However, many fast food options often contain saturated fats, which can have adverse health effects.

The longer-term health effects of keto diets are controversial, and a person may wish to use the diet for the shorter term.
