The Carb-Free Mayonnaise Myth vs. Reality
For many following a ketogenic or low-carb diet, condiments can be a hidden source of unwanted carbohydrates and sugar. While mayonnaise is often perceived as a fat-heavy food, the carb content is what really matters. The reality is that basic, traditional mayonnaise is a zero-carb food by nature. The challenge lies in navigating the modern grocery store shelves where manufacturers often add sweeteners, starches, and other stabilizers that compromise its carb-free status. Understanding the difference between pure and processed versions is the first step to making an informed choice.
The Simple Ingredients of Carb-Free Mayonnaise
True mayonnaise is an emulsion of a few simple ingredients:
- Egg Yolks: The emulsifying agent that binds the oil and acid together. They contain trace carbohydrates but not enough to register on a nutrition label.
- Oil: A neutral-flavored oil such as avocado oil, olive oil, or light vegetable oil provides the fat content and bulk of the mayonnaise. As a pure fat, it contains zero carbohydrates.
- Acid: Lemon juice or vinegar adds a tangy flavor and helps to stabilize the emulsion. Both contain negligible amounts of carbs.
- Seasoning: Salt and mustard are often added for flavor. These also contain no significant carbohydrates.
When these ingredients are used in their pure form, the resulting mayonnaise is essentially carb-free. The key is to look for brands that stick to this simple formula or, better yet, make your own at home to ensure there are no hidden carbs.
How to Spot and Avoid Carbs in Store-Bought Mayonnaise
Many commercial brands add ingredients that can quickly increase the carb count. To avoid these, you must become a label detective. Key things to look for include:
- Added Sugars: Words like 'sugar,' 'corn syrup,' 'dextrose,' or 'fructose' indicate that carbohydrates have been added. Even a small amount per serving can add up if you use mayonnaise frequently.
- Starches and Thickeners: Modified food starch or other thickening agents can contain carbs.
- Fillers: Some low-fat or 'lite' versions replace fat with water and stabilizers, which may also contain carbs.
A good rule of thumb is to look for brands specifically marketed as "Keto" or "Paleo" friendly, as these are formulated to be carb-free. Companies like Primal Kitchen or Sir Kensington's offer compliant options, but always double-check the label for confirmation.

Creating Your Own Zero-Carb Mayonnaise
For those who prefer a hands-on approach, the homemade version is king. The simplest recipes involve just five core ingredients and an immersion blender, making it nearly foolproof. You can customize the flavor by using different oils, such as avocado for a creamy, neutral taste, or a high-quality extra virgin olive oil for a more robust flavor.
Quick & Easy Zero-Carb Mayo Recipe
- Ingredients: 1 egg (at room temp), 1 cup neutral-flavored oil (avocado or light olive), 1 tbsp lemon juice or vinegar, 1 tsp Dijon mustard, and salt to taste.
- Instructions: Combine the egg, mustard, and acid in a tall, narrow jar. Pour the oil on top without stirring. Place the immersion blender head at the bottom of the jar, turn it on, and slowly pull it upward. In less than a minute, you will have thick, creamy mayonnaise.
This method guarantees a pure, keto-friendly condiment free from any added sugars or unnecessary carbs. For more recipe variations, including eggless versions, exploring keto cooking websites is a great option. For instance, this recipe from Keto Mayonnaise (Eggless) shows one can be made without eggs, offering more options.
