Keto diet challenges

When I first did a trial of the Keto diet, I found it challenging for 2 reasons:

  1. Limiting carbs took out some of the regular vegetables I eat (onion, garlic, carrots, potatoes, etc.). I found it hard to get a lot of variety and felt I was eating the same thing regularly.
  2. Getting enough healthy fat each day. This is especially challenging if you’re limiting or not eating dairy.

Homemade Keto Sauces to the rescue

Something that can help solve both of these problems is finding a few low carb sauces that you like. Sauces are great because they can add flavor (and healthy fat) to any meal with minimal effort.

I especially like making homemade sauces because they only take a few minutes to whip up and you can control the exact ingredients. Instead of spending 20 minutes at the store reading labels, just mix up a few of your own sauces and you’re all set!

Mayo is the ultimate low carb sauce. This simple homemade version uses avocado oil and is ready in just a few minutes with an immersion blender.

Use this mayo for your low carb wraps, burgers or sandwiches. You can also mix it with other sauces like hot sauce to make a quick spicy mayo.

Here are some keto recipes with mayo as a key ingredient:

Keto Stir Fry Sauce

An easy stir fry with a little cauliflower rice is one of THE BEST quick and easy keto meals. Since a lot of store bought sauces contain sugar, we made this DIY coconut aminos recipe that’s an easy homemade alternative.

Make sure you omit the maple syrup in the recipe to keep it keto friendly. You can use this sauce as a 1-to-1 replacement for soy sauce or coconut aminos in any recipe.
