Is Mayo Keto?

Mayonnaise, commonly known as mayo, is a popular condiment that is widely used in various dishes and recipes. However, for individuals following a ketogenic diet, the question arises: is mayo keto-friendly? In this article, we will explore the nutritional composition of mayo, its potential impact on ketosis, and whether it can be incorporated into a keto diet.

The Nutritional Composition of Mayo

Mayonnaise is primarily made from oil, egg yolks, vinegar or lemon juice, and seasonings. The nutritional composition of mayo can vary depending on the brand and recipe, but in general, it contains the following macronutrients per tablespoon serving:

  • Fat: Approximately 10-12 grams
  • Protein: Negligible amounts
  • Carbohydrates: Less than 1 gram

Given its high fat content and low carbohydrate content, mayo is considered a keto-friendly food. The ketogenic diet emphasizes consuming high amounts of healthy fats, moderate protein, and minimal carbohydrates to induce a state of ketosis, where the body burns fat for fuel instead of glucose.

Mayo and Ketosis

Mayonnaise can be a valuable addition to a ketogenic diet for several reasons:

  • High Fat Content: Mayo is rich in healthy fats, which are essential for maintaining ketosis. These fats provide a concentrated source of energy and help keep you feeling satiated.
  • Low Carbohydrate Content: Mayo contains negligible amounts of carbohydrates, making it an ideal choice for individuals following a keto diet. By minimizing carbohydrate intake, you can effectively maintain ketosis.
  • Versatility: Mayo can be used in a variety of keto-friendly recipes, such as salad dressings, dips, and sauces. It adds flavor and creaminess to dishes without significantly impacting carbohydrate intake.

However, it is important to note that not all mayonnaise brands are created equal. Some commercial brands may contain added sugars, vegetable oils high in omega-6 fatty acids, or other additives that can hinder ketosis. Therefore, it is crucial to read the ingredient label and choose a mayo brand that aligns with the principles of a ketogenic diet.

Homemade Mayo for Keto

One way to ensure that mayo is keto-friendly is by making it at home. Homemade mayo allows you to have complete control over the ingredients used. Here is a simple recipe for keto-friendly mayo:

  1. Ingredients:
    • 1 egg yolk
    • 1 cup avocado oil or olive oil
    • 1 tablespoon lemon juice or apple cider vinegar
    • 1 teaspoon Dijon mustard (optional)
    • Salt and pepper to taste
  2. Instructions:
    • In a bowl, whisk the egg yolk and mustard (if using) until well combined.
    • Slowly drizzle in the oil while whisking continuously until the mixture emulsifies and thickens.
    • Add lemon juice or vinegar, salt, and pepper. Whisk until well incorporated.
    • Store the homemade mayo in an airtight container in the refrigerator for up to one week.

By making mayo at home, you can ensure that it is free from any unwanted additives or sugars, making it a perfect fit for a ketogenic diet.

Incorporating Mayo into a Keto Diet

Mayonnaise can be used in various ways to enhance the flavor and texture of keto-friendly meals. Here are some ideas for incorporating mayo into a keto diet:

  • Use it as a base for homemade salad dressings or dips.
  • Spread it on lettuce wraps or low-carb bread for added creaminess.
  • Mix it with canned tuna or chicken for a quick and easy keto-friendly salad.
  • Add it to deviled eggs or egg salad for extra richness.
  • Use it as a topping for grilled meats or roasted vegetables.

Remember to consume mayo in moderation, as it is high in calories due to its fat content. While mayo is keto-friendly, excessive consumption can hinder weight loss efforts if it leads to a calorie surplus.


Mayonnaise is indeed keto-friendly, thanks to its high fat and low carbohydrate content. It can be a valuable addition to a ketogenic diet, providing flavor, creaminess, and versatility to various dishes. By choosing a mayo brand that aligns with the principles of a keto diet or making it at home, individuals can enjoy the benefits of mayo while maintaining ketosis. However, it is essential to consume mayo in moderation and be mindful of overall calorie intake to achieve desired weight loss goals.
