Is Mayo Keto? Answer, Tips & Tricks, Brands, Recipes

Mayonnaise that does not contain sugar or other carbs is a great keto condiment. The macronutrient composition of mayonnaise—high fat, low protein, and zero carb—is the perfect mix to maintain ketosis. 

Mayo is made with a few, simple ingredients: eggs, salt, mustard, oil (soybean, canola, olive, avocado), and an acidic component such as lemon juice or vinegar. 

Keto-Friendly Mayonnaise

The creamy, velvety, spreadable texture of mayo comes from the process of emulsification. The rapid whisking of the ingredients combines two liquids that don’t normally mix, in the case of mayo, it’s the oil and other liquid ingredients.

Can you have mayo on keto?

Mayonnaise is keto-friendly when not made with added sugar or artificial carbohydrates. Make sure to closely read the ingredient list and nutrition facts label to determine if the mayo fits your specific Ketogenic Diet. 

What to Look For in Keto-Friendly Mayonnaise

Despite a limited number of ingredients, there are a few important things to look for when shopping for a keto mayo.  

Oil Type

Oil is one of the most important ingredients used in mayonnaise. The type of oil greatly impacts the texture, flavor, and nutritional makeup of the final mayo. 

Common oil types include soybean oil, canola oil, extra virgin olive oil, and avocado oil. 

Soybean and canola oils are very common in store-bought mayonnaise options. Be careful, however, as mayonnaise brands that use these types of oils also add sugar and other artificial ingredients. These oils are also considered lower quality than other types of oil.   

Olive oil and coconut oil are alternative options to traditional oils that are healthier and offer more nutritional benefits. These two oils, however, contribute unique flavor to mayonnaise that can overpower the traditional flavor.

Avocado oil is another option that offers the best of both worlds. Avocados contribute healthy fats and other nutrients without any flavor. Avocado oil is a neutral oil, which means it does not contain strong flavor.  

Mayo brands that feature avocado oil generally also feature little to no sugar and no artificial ingredients.  

Added Sugars

Most mass-produced, commercial mayo brands include sugar and sugar alternatives which is a big no-no on the Keto diet. Any mayonnaise with added sugar or sugar alternatives (high fructose corn syrup) should be avoided.   

There are many sugar-free mayo brands on the market, so you don’t have to sacrifice your Keto diet to enjoy mayo. 

Added Artificial Ingredients and Preservatives

Many store-bought mayonnaise brands feature artificial ingredients and preservatives to extend the shelf life of the product. These artificial ingredients have been linked with health problems and should be avoided when possible. 

Potassium sorbate and calcium disodium EDTA are the two most common preservatives found in cheaper, mass-produced mayos. 

The less ingredients, the better. 

Blended Oils

Some major condiment brands, trying to cash in on the growing Keto Diet, have made mayonnaise options that appear to be made with avocado oil, but are also blended with other lower quality oils.

You might think you’re enjoying an avocado oil mayonnaise when in reality it has small amounts of avocado oil and relies more heavily on other types of oil. 

Keto Mayo Nutrition Information

Mayonnaise is the perfect condiment for the Keto Diet because it consists of high fat, low protein, and zero carbohydrates. It also has many health benefits that can help you maintain Ketosis and achieve your weight loss goals on the Keto diet. 

Carbs in Mayo

Fats in Mayo 

Mayo is a great keto condiment because it is high in fat.

What about traditional Mayonnaise brands?

You might be wondering how traditional mayo brands stack up on the Keto diet. These mayo brands include Duke’s Mayonnaise, Hellman’s Real Mayonnaise, Best Foods, Kewpie, and Kraft.

The answer really depends on the brand and the specific product. 

Generally, regular mayo is a keto-friendly condiment because of the main ingredients, but some of these brands add small amounts of sugar and artificial ingredients. 

Pro Tip: If the ingredient list contains sugar, but the nutrition label registers 0g sugar, it’s best to round up to 0.5g sugar and 0.5g carbohydrates to be on the safe side.

If you need a condiment and the only options are traditional mayonnaise or another condiment that contains sugar and carbs (such as ketchup), then traditional mayonnaise is going to be your best bet. But if you can select from one of our five recommended keto mayonnaise brands, you’ll be set to eat mayo without any concerns.
