I love how quick and easy this keto-friendly meal is. It's a great example of what my typical dinner looks like: high in healthy fats, protein and micronutrients. It's the ideal meal for those who practice intermittent fasting and follow a keto diet. And if your goal is to lose weight, this meal will keep your blood sugar levels stable to help you stay full for longer.

Eggs are a superfood and a keto staple. I always keep some hard boiled eggs and poached eggs in the fridge. Then I'm just minutes away from making a tasty, nutritious low-carb meal like this tuna salad or California Eggs Benedict.

If you want to give the salad an extra fat and potassium boost, simply sub the cucumber with avocado. Instead of tuna, you can use smoked salmon, mackerel or sardines. If you're not a fan of olives, use capers or a couple of chopped sun-dried tomatoes. To give the salad an extra boost of vitamins and minerals, you can part sub the lettuce with spinach, watercress or arugula. If you can do dairy, use goat cheese or feta instead of the tuna or eggs.

The dressing is very simple too. I just mix some of my homemade mayo with lemon, olive oil, chopped herbs, salt and pepper. You can add a pinch of cayenne for an extra kick. Or you can swap the olive oil with MCT oil which can raise ketone levels in case that is your goal. The options are endless!

See how easy it is to follow a keto meal plan? No excuses! 😊

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Hi there
I just downloaded the Keto Diet app and I made the 5- Minute Keto Tuna Salad on your blog.  Delicious!  I wanted to add this meal in the Planner section for today, but when I, "Tap to add meals to this day", I can't find the recipe listed.  It's from your blog.
What am I missing?


Hi Ross, you can add it directly from:
1) KetoDiet Blog section (top right there is an "add" button with a plus on it).
2) Or you can add it directly from Custom Meals > KetoDiet Blog Meals (you can also clone & modify any of the meals here), or search for the recipe name in the same section).
3) Planner day > Add > KetoDiet Blog meal > search for recipe name. In this case we are working on a universal search so you will soon be able to search across different meal categories that you now see when you tap to Add.
I hope this helps! 😊


It says place all ingredients in a mason jar and shake until well blended. Can you please clarify which ingredients go into the mason jar? Thank you.


Clarified in step one, thank you for noticing!
