Is mayo OK on keto?

Mayo is low carb. Also, it can be enjoyed on a keto diet! But it’s not the most nutrient-dense option around. We can do better! With avocado as the creamy sauce base, you swap out empty calories with healthy fats, fiber, vitamins, and minerals.

While ketosis relies on carbohydrate restriction alone, a diet that satisfies all of your body’s nutrient requirements can take thoughtful planning and practice. Using avocado as a substitute for mayo in tuna is a step in the right direction.

Is tuna salad keto?

Yes. Tuna is naturally low in carbs. As long as the ingredients mixed with tuna are also relatively low carb, tuna salad can be good for keto. 

If you are purchasing pre-made tuna salad from the store, it may have added sugars or ingredients that contribute to a higher carb count. You may be able to check the nutrition label to guide you, but generally, the carbs are low enough to fit within a keto diet. 

Use your best judgment! And while you’re at it, don’t beat yourself up if you can’t make everything from scratch at home. Allowing yourself flexibility in your diet may help you stick with it in the long run.  

Is tuna salad good for losing weight?

While weight loss is primarily driven by a calorie deficit, eating foods high in protein helps with appetite regulation. After all, protein is the most satiating macronutrient–even more so than fiber or fat. 

Pair that fully satisfied feeling from a high-protein meal with the appetite suppressing effects of nutritional ketosis and keto tuna salad can certainly support weight loss efforts. It can be much easier to control energy intake and maintain a calorie deficit when you aren’t ravenously hungry.

How to Make Avocado Tuna Salad

To elevate the basic combination, pair tuna and avocado with additional high-flavor, low carb ingredients. Blending basil, garlic, lemon juice, avocado oil, and sea salt with avocado develops a rich, buttery sauce. Celery and red onions add a beautiful pop of color and crunchy texture with every bite. 

To combine the ingredients, a food processor is the easiest option. However, manually mashing with a utensil is a tried and true alternative to consider if you don’t have access to the processor. A mortar and pestle works perfectly well.

Ripe avocados are best to use for this recipe as they puree and incorporate other ingredients more readily. The avocado will begin to turn brown when left out, but the lemon juice will help prevent this from happening.

Blend ripe avocado, fresh basil, garlic, sea salt, lemon juice, and avocado oil (or olive oil) until a smooth paste is formed. If employing a food processor for the dish, add chopped celery, red onion, and tuna fish. Give it two or three swift pulses to incorporate the ingredients. Or you can fold in your ingredients manually. 

Serve seasoned with black pepper, spooned onto a lettuce wrap, as a dip for vegetables, wrapped in a keto tortilla, or enjoy all on its own. You may even consider baking a loaf of gluten-free keto bread to make a keto tuna sandwich. 

Alternate Flavors

If you prefer a different flavor profile, consider combining avocado with lime juice, cilantro, and diced tomatoes for guacamole tuna salad. Or perhaps keep it basic with green onion, salt, and pepper. Similarly, try garnishing with chopped nuts or seeds and play around with spices. There are endless combinations to try, make your keto tuna salad however you see fit. Be sure to share your great ideas in the comments section below!
