Keto Fast-Food Guide – How to turn your favorite 10+ fast food keto

By Carine Claudepierre -

It’s is always better to make your own food, to know exactly what you put on your plate. But there is always a time when you have no other option than fast food.

Opening the door of a fast-food restaurant doesn’t have to be a dreadful experience if you are on a keto diet.

Yes, most items on the menu are carb-loaded, but there are always some less-known options that are keto-friendly sometimes with just a few changes!

Let me tell you what these changes are and how you can turn your family’s favorite fast food into a keto-friendly meal.

Keto Fast Food Guide

What to avoid in fast food?

The keto diet is all about reducing the carb intake and increasing the fat intake to put your body in ketosis.

Most fast-food restaurant food is high in carbs, high in fat. So, if you find a way to drop the carbs, it becomes keto-friendly quite easily!

Here are the few ingredients that you absolutely need to ditch on a keto diet:

  • Bread, buns, wraps, tacos, waffles – anything made with all-purpose flour. That’s why we use different flours on a keto diet.
  • High-carb vegetables – potatoes, tots, hashbrowns, potato or carrot mash, corn cobs, etc. There’s a simple rule of thumbs for vegetables. If it grows underground, you should avoid it. If it’s not green, you should avoid it.
  • Anything battered or breaded – chicken nuggets, fish sticks, cheese sticks, etc. The batter is always made with high-carb flour.
  • Rice and Beans – too high in carbs.
  • Sauces, Dressings – they are most of the time loaded in carbs. Some sauces are made mostly of fat and protein (some mayo, Bearnaise), but others are mostly made of carbs and oil.
  • Desserts – always high in carbs.
  • Drink – sugar-loaded sodas and juices. Only go for water or sugar-free sodas.

What to order in fast food on a keto diet?

There are still many things you can order in fast food restaurants on a keto diet!

The following ingredients are perfectly keto-friendly:

  • Meat – with no sauce, and no batter, but with cheese, green vegetables.
  • Keto-friendly vegetables – make sure to print my keto vegetable list to make sure they are keto-friendly. Green vegetables are almost always keto-friendly, and some non-green vegetables are fine in smaller amounts.
  • Dairy products (except milk) – almost all dairy products are keto-friendly. So cream, cheese are all good!

Fast-food replacers

Did you know you can still eat a burger on a keto diet?

Here’s the anatomy of a perfectly keto-friendly burger.

  • Large leaf of lettuce
  • Small slice of tomato
  • A few slices of red onion
  • Cheese
  • 100% Meat Pattie
  • Sugar-free Tomato Sauce
  • Large leaf of lettuce
keto-friendly burger

You can eat it because you’ve replaced all the high-carb ingredients with low-carb ones.

Here are all the common replacements you can make:

  • Swap buns or wraps for lettuce
  • Replace ketchup with mayo (check the ingredients for sugar)
  • Swap battered meat for just meat
  • Swap fries for a salad with no sauce, no croutons

What to order at common fast-food joints?

Now that you know the basics, let’s have a look at what keto-friendly food you can have at specific fast-food restaurants!

Below is the list of the top American fast-food chains, and some of the top Australian, UK, and New Zealand fast foods!

1. How to eat Keto at Mcdonald’s?

First, let me tell you that Mcdonald’s has a Nutrition Calculator on their site. Since they change their recipes regularly, make sure to double-check the data!

Keto-friendly option at Mcdonald’s

To make your favorite Macdonald’s burger keto-friendly, order it bunless or wrapped in lettuce.

  • Bunless Egg McMuffin: 3g Net Carbs

There’s nothing keto-friendly at the McCafe.

2. How to eat Keto at Starbucks?

Starbucks has a handy online menu with full nutrition however their calculator doesn’t take into account your modifications. So if you choose Almond Milk, it’ll still show the carbs for regular milk.

For the full nutrition of all beverages with plant-based milk, you need to open their Drink Nutrition PDF and Food Nutrition PDF – quite a bit more cumbersome to use.

Keto-friendly options at Starbucks

  • Caffe Mistro with Soy Milk (Grande or smaller) – a Grande Soy Mistro has 6g of Net Carbs.
  • Caffe Americano (any size) – this milk-free Coffee has only 4g of Net Carbs in Venti size.
