Are McDonald’s fries keto? This is a common question among individuals following the ketogenic diet, which is a low-carb, high-fat diet that has gained popularity in recent years. The ketogenic diet aims to put the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. In this article, we will explore whether McDonald’s fries can be included in a keto diet and provide valuable insights for those following this eating plan.

Understanding the Ketogenic Diet

Before we delve into the topic, it is important to understand the basics of the ketogenic diet. The diet typically consists of consuming high amounts of healthy fats, moderate protein, and very low carbohydrates. By drastically reducing carbohydrate intake, the body is forced to enter a metabolic state called ketosis. In this state, the body starts using fat as its primary source of energy, leading to weight loss and other potential health benefits.

The Nutritional Profile of McDonald’s Fries

McDonald’s fries are undoubtedly delicious, but they are not considered keto-friendly due to their high carbohydrate content. Let’s take a closer look at the nutritional profile of McDonald’s fries:

  • A small serving of McDonald’s fries (71 grams) contains approximately 230 calories.
  • It also contains 29 grams of carbohydrates, 3 grams of protein, and 11 grams of fat.
  • Out of the 29 grams of carbohydrates, 3 grams come from dietary fiber.

While the fiber content can be subtracted from the total carbohydrates to calculate net carbs, the remaining 26 grams of net carbs are still relatively high for a keto diet. The recommended daily carbohydrate intake for most individuals on a keto diet is typically around 20-50 grams.

Impact on Ketosis

Consuming McDonald’s fries can have a significant impact on ketosis due to their high carbohydrate content. The body will prioritize burning the carbohydrates from the fries for energy instead of fat, which can potentially kick you out of ketosis. Additionally, the high glycemic index of the fries can cause a rapid spike in blood sugar levels, leading to insulin secretion and hindering the fat-burning process.

Alternatives for Keto-Friendly Fries

While McDonald’s fries may not be suitable for a keto diet, there are several alternatives that can satisfy your cravings without compromising your ketosis. Here are some keto-friendly options:

  • Vegetable Fries: Replace traditional potato fries with low-carb vegetables such as zucchini, turnips, or jicama. These can be sliced into fry-like shapes, seasoned, and baked or air-fried until crispy.
  • Avocado Fries: Avocado is a healthy source of fats and can be sliced, coated in almond flour or crushed pork rinds, and baked until crispy.
  • Cauliflower Fries: Cauliflower is a versatile vegetable that can be transformed into delicious fries. Simply cut the cauliflower into florets, coat with olive oil and spices, and bake until golden brown.


While McDonald’s fries are undeniably tasty, they are not suitable for a keto diet due to their high carbohydrate content. Consuming them can hinder ketosis and the fat-burning process. However, there are plenty of keto-friendly alternatives available that can satisfy your fry cravings without compromising your dietary goals. By opting for low-carb vegetable fries or homemade alternatives like avocado or cauliflower fries, you can enjoy a delicious snack while staying in ketosis.
