Back in the winter of 2021 when I was trying to shed some pesky COVID pounds I decided to experiment with a Keto diet. So many people talked about it including my best friend who has a masters in nutrition.

Upon looking into it and reading a few books, I decided to give keto an Alkaline Keto Diet a try. Keto worked for me but I didn’t want to focus on acidic high fat foods like cheese but to include lots of low carb vegetables and healthy vegan fats like avocados and nuts.

Is Miso Keto Friendly?

The quick answer is YES MISO IS KETO FRIENDLY! Isn’t that great news?

To understand why miso is keto friendly we need to look at what miso is and what ingredients it’s made from.

What is Miso?

By Definition, miso is a fermented paste that’s made by inoculating soybeans with koji (a type of mold) that has been cultivated from rice, barley, or soybeans.

Wait a second? Rice and barley are high in carbs and not keto friendly. So how is miso keto? Since miso paste is made with a byproduct of rice and barley it’s going to be low in carbs.

Miso is predominantly used as a seasoning. For instance, miso is commonly used as an ingredient in dips, dressings and soups like miso soup! So you don’t need to use miso in large quantities because a little goes a long way. Miso paste has a strong flavor. In fact, too much miso would make your food overly salty.

For those of you who are avoiding soy you can use chickpea miso instead.

Common Questions on Miso and Keto

Is miso high in carbs?

No, miso is not high in carbs considering how little of it is used in a recipe.

Miso paste has 7 grams of carbs per two teaspoons and 3-4 grams of net carbs per serving. I use 1-2 tablespoons in most recipes that have 16 servings. So divided out over many servings that is not a lot of carbs. You can easily enjoy foods like miso soup and easily stay below the recommended 50 grams of carbs per day maximum which is required to keep your body in ketosis.

Is Miso soup O.K. for keto?

Yes! Miso is O.K. for keto because it’s low in carbohydrates. It has 7 grams of carbs per two teaspoons and 3-4 grams of net carbs per serving. Not only is keto low in carbs but it’s also low in fat.

While high fat foods are recommended on a Keto Diet, eating miso soup provides the body with probiotics, and it’s free of ingredients that aren’t recommended on a Keto Diet. Miso is also low in sugar which is great because sugar intake is supposed to be limited on a Keto Diet.

Miso soup is a low fat healthy food but if you’re on a Keto Diet make sure to pair it with healthy fats like avocado or fish.

Does miso soup have carbs?

Miso soup is very low in carbs. It has only 3 grams of carbs per serving. This will of course vary based on the recipe and serving size but in general all of the ingredients commonly used to make miso soup are low in carbs, sugar and fat.

These ingredients include miso, sea vegetables, tofu, water, onions, carrots, ginger, scallions and mushrooms.

Is soy allowed on keto?

Yes, soy is allowed on a Keto Diet itself but is usually consumed in the form of soy sauce. Although soy is low in carbs its generally highly processed which is not recommended on any healthy diet including keto.

How to Make Keto Miso Soup

Step 1: Slice the onions, carrots, celery and shiitake mushrooms.  In a large soup pot sweat them for about ten minutes.  Meanwhile, soak the sea vegetables in water.

Step 2: rinse the sea vegetables and put them in the soup pot.  Sauté the soup for another ten minutes or so.  Until the vegetables are soft.  Add water and bring the soup to a boil.  Meanwhile peel and grate the ginger.  To get the juice out of the ginger place the shredded pieces in a cheese cloth and squeeze them over a bowl.  Set it aside for later.  You can also just run the ginger through a juicer if you have one.

Step 3: Once the soup is boiling lower it to a simmer and continue to cook for another 10-15 minutes with the lid off.  Turn the stove off and let the broth cool for a few minutes.  Then Mix the miso paste in with a whisk.  Make sure that the miso paste is fully mixed in and that there are no chunks.  You don’t want to eat chunks of salty miso while enjoying your soup!

This miso soup is the vegan version of chicken soup.  It is healing, full of probiotics and tasty to boot.  If you reheat it and it tastes too salty just add more water! 
Don’t heat it too high after adding the miso paste or you will kill the good probiotics.  Which are found in the paste.
If you don’t want to chop all of the vegetables you can use a food processor with the slicing blade or a mandolin.
