How This Low-Carb Recipe Compares to a Traditional Recipe

There's one thing that really sets these keto lemon bars apart from most traditional recipes:

They use almond flour, not regular flour.

Now you might be asking yourself: can one ingredient really make that much of a difference? The answer is you bet. 

Just consider that [1][2]:

  • 100g of almond flour has 12g of carbs, whereas traditional flour has 76g.
  • 100g of almond flour has fewer than half the calories of traditional flour.
  • Almond flour has a glycemic load of 0, meaning it won't affect or spike your blood sugar, whereas regular flour has a glycemic load of 54 (non-keto dieters aim for 100/day or less).

Pretty stark difference, right? 

You're taking out all the unhealthy stuff and replacing it with wholesome, high-fat goodness that makes these treats both satisfying and good for you.

Ingredient Spotlight: Lemons

All of us have heard the old story about how citrus fruits like lemons apparently saved sailors from getting scurvy on long boat rides across the ocean. But what else can we say about the benefits of fresh lemons?

Actually, we can say a lot. Check out all these health benefits:

  • Lemons are rich in vitamin C (citric acid) which is good for immune health (and, it turns out, preventing scurvy) [3][4].
  • Lemons contain tons of polyphenols, a powerful antioxidant that helps ward off oxidative stress, lowers blood pressure, and regulates the metabolism [5].
  • Lemons have a natural anti-aging effect, and can also help reduce fatigue [6].
Those Naval ships were onto something, eh? Fret not, though. You don't have to be a sailor to enjoy these keto lemon bars!
