Mayonnaise is a keto-approved condiment, but not all store-bought mayonnaise is keto-friendly. Store-bought mayonnaise is often made with soybean oil, canola oil, and other vegetable oils, which are high in omega-6 fatty acids and can contribute to insulin resistance and inflammation. However, mayonnaise made with olive oil is keto-friendly and can be easily made at home in just a few minutes. Olive oil is rich in monounsaturated fatty acids (MUFAs), which offer health benefits such as reduced heart disease risk. Additionally, avocado oil and MCT oil are also popular choices for keto-friendly mayonnaise.

What You'll Learn

Store-bought olive oil mayo often contains other oils
While mayonnaise is a keto-approved condiment, not all store-bought olive oil mayo products are suitable for the keto diet. This is because store-bought olive oil mayonnaise is not made exclusively with olive oil. It often contains other oils, such as soybean oil, canola oil, and vegetable oils, which are high in omega-6 fatty acids and can contribute to insulin resistance. These additional oils are not keto-friendly and can affect the health benefits of the product.
Some popular brands of mayonnaise, such as Hellmann's, offer an olive oil version. However, these products may still contain other ingredients that are not ideal for the keto diet, such as canola oil. Therefore, it is important to carefully read the ingredient labels when purchasing store-bought olive oil mayonnaise to ensure that it aligns with the keto diet guidelines.
To ensure that your mayonnaise is truly keto-friendly, it may be preferable to make your own at home. By making your own mayonnaise, you can control the ingredients and ensure that only keto-approved oils, such as olive oil, avocado oil, or MCT oil, are used. Homemade mayonnaise allows for the incorporation of healthy fats and the avoidance of sugars and harmful additives commonly found in store-bought products.
When making keto-friendly mayonnaise at home, it is important to use the right type of olive oil. Extra light olive oil is recommended as it is tasteless and will not overpower the flavour of the mayonnaise. On the other hand, extra virgin olive oil may make the mayonnaise taste bitter due to its strong flavour.

To make keto mayo, start by placing one egg, apple cider vinegar, and salt into a blender cup and blend for 20 seconds. Then, add oil drop by drop until the mixture thickens. You can use olive oil, avocado oil, or a combination of the two. Once the mixture is thick, you can add the oil more quickly. When all the oil has been added, stir in lemon juice, and add more salt and lemon juice to taste. You can also add in some Dijon mustard for a sweeter mayo, or a sugar-free hot sauce for a spicy mayo.
Your homemade keto mayo will last about a week in the fridge, and it can also be frozen for up to 6 months. Making your own keto mayo is a great way to ensure that you're getting a healthy, tasty condiment without any unwanted additives or preservatives.

Olive oil is rich in monounsaturated fats
Olive oil is a rich source of monounsaturated fats, which are known to benefit heart health. According to researchers, consuming monounsaturated fatty acids (MUFAs) from plant sources like olive oil can lower an individual's risk of heart disease. Olive oil is also said to protect against certain other health conditions.
When it comes to the keto diet, olive oil is a great option for mayonnaise, which is a keto-approved condiment. Mayonnaise made with olive oil is healthier than store-bought mayonnaise, which often contains unhealthy vegetable oils, soybean oil, and added sugars. By making your own mayonnaise with olive oil, you can avoid these harmful additives and incorporate healthy fats into your keto diet.
However, it is important to note that olive oil has a strong flavour that may not appeal to everyone. Some people may find the taste bitter, especially if using extra virgin olive oil. As a solution, it is recommended to use extra light olive oil, which is tasteless and has a pale colour.
For those following a ketogenic diet, Medium-Chain Triglycerides (MCT) oil is also a good option to consider for making keto mayonnaise. MCT oil is a concentrated source that can improve weight loss results and provide fuel for the brain, heart, and muscles. Combining MCT oil with avocado oil is a popular choice to avoid solidification and achieve the desired consistency.
In conclusion, olive oil is a nutritious and flavourful choice for those following a keto diet. Its high content of monounsaturated fats offers heart-healthy benefits and protects against certain health conditions. By making homemade mayonnaise with olive oil, individuals on the keto diet can ensure a healthier option that aligns with their nutritional goals.

Avocado oil is a popular alternative
Mayonnaise is a keto-approved condiment, but it is important to choose the right ingredients. While store-bought mayonnaise is convenient, it often contains unhealthy vegetable oils, sugar, preservatives, and additives. These ingredients can contribute to insulin resistance and increase inflammation in the body. Therefore, it is recommended to make your own mayonnaise at home using healthy oils such as olive oil or avocado oil.
When making keto-friendly mayonnaise with avocado oil, it is important to add the oil slowly while continuously working the mixture. This process ensures the proper emulsification of the ingredients, resulting in a smooth and creamy mayonnaise. The avocado oil keto mayonnaise can be seasoned with salt and pepper to taste, and it pairs well with a variety of dishes, including salads, proteins, and low-carb bread.
Primal Kitchens is a popular brand that offers an avocado oil-based mayonnaise with no carbs, no added sugars, and 12 grams of fat per tablespoon. This product is a favourite among dieters following a ketogenic diet. However, it is important to note that some individuals may find the taste of avocado oil mayonnaise less appealing than traditional mayonnaise. It is always a good idea to experiment with different recipes and brands to find the one that suits your taste preferences and dietary needs.
In conclusion, avocado oil is a popular and nutritious alternative for those seeking a low-carb, keto-friendly mayonnaise. By making your own mayonnaise with avocado oil, you can avoid the unhealthy ingredients found in store-bought options and customise the flavour to your liking.

MCT oil can improve weight loss results
Mayonnaise is a keto-approved condiment, and you can make your own with the help of healthy fats in olive oil. Store-bought mayonnaise, including olive oil mayonnaise, is made with vegetable oils like soybean oil and canola oil, which are high in omega 6 fatty acids and sugar. Making your own keto-friendly mayonnaise at home is a healthier option.
MCT oil, or medium-chain triglycerides, is a popular supplement used to aid fat loss and increase energy. It is made from a type of fat that is easier for your body to digest and absorb than long-chain triglycerides, which are found in most fats. This allows for quicker conversion into energy. MCT oil is usually made from coconut or palm kernel oil.
MCT oil can be used as part of a ketogenic diet, which is very low in carbs and high in fat. While some studies suggest that a ketogenic diet can aid weight loss, the long-term effects are not known. A 2015 review of 13 randomized controlled trials found that MCTs supported modest weight loss, fat loss, and reduced body size. However, the authors noted that many of the studies were of questionable quality and may have been influenced by industry funding.
Consuming MCT oil as part of a weight-loss plan has been shown to improve weight loss compared to olive oil. One study found that subjects consuming MCT as part of their weight-loss diet lost an average of 1.7 kg more than those consuming olive oil. MCT oil may also help lower LDL ("bad") cholesterol and increase HDL ("good") cholesterol.
While MCT oil can be a useful tool for weight loss, it should be used in moderation. Some potential negatives include a high-calorie count, which can cause weight gain, and large amounts of saturated fat, which may raise cholesterol levels. Additionally, MCTs may stimulate the release of hunger hormones, leading to overeating. It is important to speak to a dietitian to determine the appropriate dose for your individual needs.
