Is Oats Keto Friendly: Exploring the Compatibility of Oats with the Ketogenic Diet


When it comes to following a ketogenic diet, one of the key considerations is the selection of foods that align with its principles. The ketogenic diet, known for its emphasis on low-carbohydrate and high-fat intake, can be a challenging dietary approach to adopt. Therefore, it is essential to have a clear understanding of the compatibility of various food items with the ketogenic diet. In this article, we delve into the question, “Is oats keto friendly?” and explore the factors that determine the suitability of oats within the context of the ketogenic diet.

Is Oats Keto Friendly?

Oats are a popular breakfast staple and are widely recognized for their nutritional benefits. They are a rich source of fiber, vitamins, and minerals. However, when it comes to the ketogenic diet, oats pose a challenge due to their relatively high carbohydrate content. Let’s examine the macronutrient composition of oats to determine their compatibility with the ketogenic diet.

The Nutritional Profile of Oats

A 100-gram serving of oats typically contains the following macronutrients:

  • Carbohydrates: 66 grams
  • Protein: 17 grams
  • Fat: 7 grams
  • Fiber: 11 grams

As we can see, oats are relatively high in carbohydrates, with a significant portion of their weight comprising this macronutrient. This carbohydrate content raises concerns about their suitability for a ketogenic diet, which typically restricts carbohydrate intake to induce a state of ketosis.

Carbohydrate Content and Ketosis

To achieve and maintain ketosis, it is essential to restrict carbohydrate intake to a low level, usually around 20-50 grams per day. This limited carbohydrate consumption prompts the body to shift from relying on glucose for energy to utilizing stored fats as its primary fuel source.

Given that oats contain approximately 66 grams of carbohydrates per 100-gram serving, it is evident that they are not inherently keto-friendly. However, there are ways to incorporate oats into a ketogenic diet with careful consideration and moderation.

Strategies for Including Oats in a Ketogenic Diet

While oats may not be ideal for strict adherence to a ketogenic diet, there are strategies you can employ to enjoy them while minimizing their impact on ketosis. Here are a few options to consider:

1. Portion Control

Moderation is key when it comes to incorporating oats into a ketogenic diet. By carefully measuring and controlling your oat portion size, you can limit the carbohydrate intake while still enjoying the nutritional benefits they offer. Opting for smaller serving sizes, such as ¼ cup or 30 grams, can help maintain a more favorable macronutrient balance.

2. Balancing with Other Macronutrients

To counterbalance the higher carbohydrate content of oats, it is essential to ensure that the remaining meals of the day are low in carbohydrates and higher in healthy fats. This approach can help maintain the desired state of ketosis while allowing for the inclusion of oats in your diet.

3. Pairing with Healthy Fats

To make your oatmeal more compatible with a ketogenic diet, consider adding sources of healthy fats, such as nuts, seeds, coconut oil, or full-fat dairy products. This addition of fats helps slow down the digestion and absorption of carbohydrates, minimizing the impact on blood sugar levels and ketosis.

4. Choosing Steel-Cut or Rolled Oats

When selecting oats, opt for steel-cut or rolled oats instead of instant oats or flavored oatmeal packets. Steel-cut and rolled oats undergo minimal processing, retaining more of their natural nutrients and fiber. They also have a lower glycemic index compared to instant oats, which means they have a slower impact on blood sugar levels.

5. Preparing Overnight Oats

Another way to incorporate oats into a ketogenic diet is by preparing overnight oats. By soaking oats in a liquid such as almond milk or coconut milk overnight, you can soften them without the need for cooking. This method preserves the nutritional integrity of the oats while allowing for easier digestion and better glycemic control.

FAQs about Oats and the Ketogenic Diet

1. Can I eat oat bran on a keto diet?

Oat bran is the outer layer of the oat grain and contains more fiber and protein compared to regular oats. While it is lower in carbohydrates, it still needs to be consumed in moderation on a ketogenic diet. Aim for small portions and consider balancing it with other low-carb foods to maintain ketosis.

2. Can I consume oat milk on a ketogenic diet?

Oat milk, made from soaked and blended oats, tends to be higher in carbohydrates and lower in fat compared to other plant-based milk alternatives like almond milk or coconut milk. It is advisable to avoid oat milk if you are following a strict ketogenic diet. Instead, opt for unsweetened almond milk or coconut milk.

3. Are there any keto-friendly oat substitutes?

Yes, there are several keto-friendly alternatives to oats that you can consider. Chia seeds, flaxseeds, hemp hearts, and shredded coconut are nutritious options that provide similar texture and versatility. These alternatives are lower in carbohydrates and higher in healthy fats, making them more compatible with a ketogenic diet.

4. Can I have oats occasionally on a keto diet?

If you have already achieved your desired state of ketosis and have established metabolic flexibility, occasional consumption of oats in controlled amounts may be possible without completely derailing your progress. However, individual responses to carbohydrate intake can vary, so it is crucial to monitor your body’s reaction and adjust accordingly.

5. Are there any health benefits to eating oats?

Yes, oats offer several health benefits when consumed as part of a balanced diet. They are an excellent source of dietary fiber, which aids digestion and supports heart health. Oats also contain various vitamins, minerals, and antioxidants that contribute to overall well-being. However, it is important to consider these benefits in the context of your specific dietary goals and restrictions.

6. Can oats be included in a low-carb diet that is not strictly ketogenic?

Absolutely! If you are following a low-carbohydrate diet that is not necessarily ketogenic, oats can be a nutritious addition in moderation. Adjusting portion sizes and incorporating oats into a well-rounded meal plan can allow for their inclusion while still maintaining a lower carbohydrate intake.


In conclusion, oats are not inherently keto-friendly due to their relatively high carbohydrate content. However, with careful planning and moderation, it is possible to incorporate oats into a ketogenic diet without jeopardizing ketosis. By employing strategies such as portion control, balancing macronutrients, and pairing oats with healthy fats, you can enjoy the nutritional benefits of oats while staying true to your ketogenic goals. As with any dietary consideration, it is essential to listen to your body and make adjustments based on your individual needs and responses.

Remember, achieving and maintaining ketosis requires a comprehensive approach that extends beyond the inclusion or exclusion of specific foods. Consult with a healthcare professional or registered dietitian to ensure that your dietary choices align with your health goals and specific needs.
