How To Make A Low Calorie Tuna Sandwich

Tuna Sandwich

Listen… if there’s one thing I cannot do on a weight-loss journey, it’s build a whole sandwich with only two slices of bread 😭
By the time I take two bites, I already feel defeated before the meal even starts!

That’s why switching to low-calorie keto bread has been one of my best food decisions. I broke everything down in yesterday’s post (you can check it out here), but the highlight is this:
👉 I can now eat four slices with my full chest, stay full, and still meet my calorie goals.
A win is a win!

So today’s Tuna Sandwich is exactly that: low calorie, high fiber, filling, and perfect for breakfast. The whole meal is 224 calories with a fantastic macro breakdown:

  • 40.1g fiber
  • 26.1g protein
  • 18.2g net carbs
  • 5.8g fat

And yes, it’s super satisfying even with the simplest filling.

You can absolutely bulk up your tuna mix with veggies for more fiber and volume, but I wasn’t very hungry this morning, so I kept it simple and paired it with tea.
And by tea, I mean actual tea; a teabag steeped in hot water.
My country people, that thing we do with milk + Milo?
Please… that’s hot chocolate, not tea 😭😂

I used an unflavored green tea bag (0 calories) sweetened with stevia (0 calories), so breakfast calories came ONLY from my sandwich. Clean and simple.

Have you tried low-calorie breads yet? Because I’m not going back.
