Keto Tuna Salad

I know how hard it is to follow a strict healthy diet regime every day and eat mindfully with all the distractions out there.

Personally, I find that when I eat low carb and keto dishes with occasional comfort foods I never feel deprived.

Mindful eating keeps me satisfied and generally keeps my waistline from expanding.

But, it doesn’t necessarily mean that our path to living a healthier life must be filled with tasteless and bland options.

In fact, there are numerous delicacies out there like this Keto Shepherd’s Pie or Keto Chicken Soup which not only satisfy our taste buds but are also super beneficial for our health and wellness.

This Keto tuna salad is a classic tried and tested recipe that not is only delicious, but good for us too!

I know a lot of individuals refrain from following a keto diet maybe, because the idea to consume more fats may seem like an unhealthy option.

But, believe me the keto diet is really helpful in maintaining your health as it includes the use of heart-healthy good fats. Be sure to Read more about Keto vs Low carb diets.

So, before jumping to this keto-friendly tuna salad recipe, let’s have a quick look at some interesting facts about the keto diet.

What is Ketogenic Diet and How is it beneficial for us?

The idea of keto diet majorly revolves around substantially reducing the intake of carbohydrates and replacing them with fats. This reduction in carbs will put our body into ketosis mode.

Now, ketosis is a metabolic state where our body becomes really efficient in burning stored fat to produce energy.

Let me explain this further; when we consume very low amounts of carbs, our liver produces ‘Ketones’ by metabolizing the fat.

Ketones are an alternative fuel for your body which it uses when blood glucose levels are low. Besides the body, ketones are an excellent source of energy for the brain.

The fact that I mentioned this point is because our brain cannot directly run on fats. It either requires glucose or ketones to maintain its healthy functioning.

Also, there are many sub-versions of this diet. However, one of the most widely accepted and researched type is Standard Ketogenic Diet (SKD) which focuses on the low carb (5%), moderate protein (20%), and high fat (75%) intake.

For the slightly other versions be sure to checkout the Keto Macro Calculator for your personal macronutrients.

A range of studies indicates the following benefits of the standard ketogenic diet.

  • Sticking to SKD religiously can help us to lose weight without consciously tracking our calories and food intake.
  • It shields us from chronic conditions such as type-2 diabetes.
  • It reduces the risk of cardiovascular diseases.
  • May help to improve the symptoms of various mental conditions such as Alzheimer’s, Parkinson’s, and Epilepsy.

Lastly, remember that the topic of the keto diet is recent and hot in the field of biological science, and some of these researches are still in early phases to be conclusive.

List of Ingredients

  1. Canned tuna, drained
  2. celery, finely diced
  3. Red onion, finely minced
  4. Flat-leaf parsley, finely minced
  5. Mayonnaise, add a little at a time**see notes
  6. Dijon or stone ground mustard
  7. Fresh lemon juice
  8. Salt and pepper

Noteworthy Things About Ingredients

  • I have used tuna packed in water which gives this dish a fresh and wholesome taste.
  • Incorporating diced celery and red onions impart crunchiness to this keto tuna salad. Don’t skip on this one.
  • Adding freshly squeezed lemon juice, parsley, and Dijon/stone ground mustard will greatly intensify the flavors of the whole dish so, don’t skip them either.
  • I have used homemade mayonnaise which is a key ingredient that grants a really creamy and dense taste to this low carb tuna salad. And I would recommend that you too make your mayonnaise at home preferably with olive/avocado oil as store-bought mayonnaise tends to have vegetable oils in its content which are generally considered as bad fats and thus are not an ideal keto ingredient.

How To Make Keto Tuna Salad

Tuna salad is easy to make and only requires a few minutes of chopping ingredients before mixing everything together.

I like to chill my salad before serving for about an hour, but that’s when I’m not in a rush or hangry!

Serve on a bet of lettuce, with celery sticks, roll in a low carb wrap or enjoy open faced over grain free bread and make a keto tuna melt.

Pro Tip – Use a hand mixer, pastry blend or a hand chopper to break up tuna.
