The Core Ingredients of Mayonnaise
At its most basic, traditional mayonnaise is an emulsion of oil, egg yolks, an acid (like vinegar or lemon juice), and a pinch of salt. When made with these simple ingredients, the resulting condiment is naturally high in fat and contains virtually no carbohydrates, making it an excellent fit for the ketogenic diet's macronutrient requirements. The high fat content helps increase satiety and provides the energy needed to stay in ketosis.
How Store-Bought Mayo Can Derail Ketosis
While the concept of mayonnaise is perfectly aligned with keto, the reality of many mass-produced commercial brands is often different. Manufacturers frequently add ingredients that can compromise ketosis or are not ideal for overall health.
Problematic Oils
Many budget-friendly mayonnaise brands use highly processed vegetable oils, such as soybean, canola, or regular sunflower oil. While not directly loaded with carbs, these oils are high in omega-6 fatty acids and can cause inflammation, a concern for many following a ketogenic lifestyle for optimal health. Look for brands that use high-quality, healthier oils.
Hidden Sugars and Starches
Some companies add sugar or high-fructose corn syrup to enhance flavor or texture, even in products that seem savory. Even if the label lists 0g of sugar per serving, it's wise to check the ingredient list. The serving size is often small, and small amounts of sugar can add up quickly if you use more than one tablespoon. Similarly, modified food starch can be used as a thickener and can also contribute to the overall carb count.
Artificial Preservatives
To extend shelf life, commercial mayonnaises may contain artificial preservatives like calcium disodium EDTA or potassium sorbate. Many keto practitioners prefer to avoid these artificial additives for cleaner eating.
Homemade vs. Store-Bought Mayonnaise
Understanding the differences between homemade and store-bought mayonnaise is key to making a keto-compliant choice. The best mayo for a keto diet is either a store-bought version with a clean ingredient list or one you make yourself.
| Feature | Homemade Mayo | Store-Bought Mayo (Conventional) |
|---|---|---|
| Oil Quality | You choose high-quality oils like avocado or olive oil, avoiding inflammatory seed oils. | Often uses processed, inflammatory seed oils (soybean, canola). |
| Carb Content | Typically zero net carbs, assuming no added sugar. | May contain trace amounts of carbs from hidden sugars or starches. |
| Additives | Free from artificial preservatives and emulsifiers. | May contain artificial preservatives like EDTA to extend shelf life. |
| Freshness & Flavor | Made fresh, often with a richer, more vibrant flavor profile. | Can have a blander, more uniform flavor due to processing. |
| Cost | More cost-effective if you already have the ingredients. | Varies widely, with keto-friendly brands being more expensive. |
| Convenience | Requires a few minutes of prep and blending. | Grab-and-go convenience, but requires label reading. |
