Is Miso Soup Keto-Friendly?

Miso soup is a much-loved Japanese meal with low carbs and other benefits that you may love. Let’s understand what makes miso soup keto-friendly to ease your mind on the diet.

Are There Carbs in Miso Soup?

How many carbs are in miso soup? You must count the net carbs in the soup on the keto diet. Everyday Health points out that typical keto diets entail eating 20-50 net carbs daily (2). Since your body doesn’t digest fiber, it doesn’t count toward your daily carbohydrate intake. 

You can calculate your net carb intake manually or with a calculator. Medical News Today suggests deducting the fiber amount and half of the sugar alcohol content from the total carbs to get the net carbs (9). Alternatively, Sure Keto’s net carb calculator does the math (13). It determines that you’ll eat 2.4 net g of carbs in one cup of miso soup.

The goal amount of net carbs daily differs among people. Knowing this, you can use the keto macros calculator to determine how many net carbs you should eat daily (16). It also gives you rough ideas of how much protein and fat you should consume daily to stay in ketosis. 

Miso Soup Protein (Vegan & Meaty)

The Recommended Dietary Allowance (RDA) is 0.8 grams of protein per kilogram of body weight daily (8). The keto diet recommends eating 20-25% protein, 5-10% carbohydrates, and 70-75% fat from your daily calories (2). Miso soup helps vegans eat protein, while meat eaters can add more protein and fat with certain additions. Let’s see how.

Is Tofu Allowed on Keto?

The carbs in miso soup with tofu welcome vegans to enjoy low-carb meals with enough protein to enter ketosis. The USDA suggests a 116-gram block of tofu has 9.37 g of protein, 1.82 g of net carbs, and 5.54 g of fat (26). Also, miso soup already contains some protein.

Mama Bear’s Cookbook recipe is a vegan-friendly miso soup to try on keto with a simple substitution (14). Many recipes use chicken broth but substitute it with dashi or vegetable broth to ensure your meal is vegan-friendly.

Meanwhile, the Mama Bear recipe has 4 g of protein, 11 g of net carbs, and 4 g of fat per serving (14).  Add some tofu blocks, and you’ll push your protein count higher. The plant-based protein will ensure you’re revving up the natural protein in miso soup. 

Bonus: Miso Soup Nutrients May Benefit Vegans

WebMD suggests miso soup is nutrient-rich with zinc, copper, manganese, calcium, iron, and magnesium (22). Meanwhile, it contains B and K vitamins. The Vegan Society recommends that vegans make an effort to consume enough vitamin B12 daily (27). 

You can eat vitamin B12 fortified foods, take supplements, and consume foods high in B vitamins. Eating too little vitamin B12 can put you at risk of heart disease, pregnancy complications, or nervous system disorders. However, miso soup is rich in B vitamins.

What Meat Can You Eat in Keto Miso Soup?

The USDA says miso paste, a key ingredient in the soup, has keto-friendly values (20). A tablespoon of miso paste has 2.18 g of protein, 3.4 g of net carbs, and 1.02 g of fat. You’re already getting some protein and fat, but it helps to add more to your daily needs.

Men’s Health recommends fatty meats to add protein and fat to meals (1). Miso soup traditionally uses chicken and tofu more than other meats. A fatty portion of chicken with its skin contains 25 g of fat and 14 g of protein per 4-ounce serving.  

However, you can experiment with strip, porterhouse, t-bone, or ribeye steak. They aren’t typical miso soup ingredients, but then again your taste buds aren’t the same as everyone’s. Let’s see what ingredients you find in miso soup to understand the benefits of keto and miso soup.

Miso Soup Keto Ingredients

Miso soup has key ingredients, albeit you can add others. The coming recipes will have set ingredients, but you can experiment with other additives from the keto-friendly list. Discover miso soup’s keto-friendly heart, foundation, and tasteful touches. 

The Heart of Miso Soup – Miso Paste

Miso soup starts with fermented soybean paste. A lot of confusion exists around the source of miso paste. Fortunately, the paste only uses the koji derived from rice or barley, not high-carb rice (28). The Japanese use koji to ferment soybeans and add salt. 

Miso paste ferments and ages for months to years, creating a stronger umami flavor as the blend darkens. The grain koji type can also change the umami strength, such as white miso paste from rice koji. Here’s a quick rundown of miso pastes (28):

• Shiro, a white, yellow, or light-colored miso paste has a milder, sweeter taste with a shorter fermentation process, lasting 3-12 months. It uses more rice koji to balance the soybeans for the delicate flavors.
• Aka, a red, brown, or dark miso paste has an intense umami taste with a longer fermentation process, lasting six months to ten years. It has a higher soybean-to-koji ratio, possibly using barley or soybean koji.

The Foundation of Miso Soup – Broth

Miso soup uses a broth to dilute the paste. Let’s look at some broths popular in miso soup to suit different keto followers. 

• Chicken broth is a favorite miso soup ingredient. It adds more protein and thins your miso soup enough to enjoy it. One cup of chicken broth contains 1.59 g of protein, 0.52 g of fat, and 1.1 g of net carbs (25).
• Dashi broth is a favorite used for miso soup in Japan. However, it lacks protein and fat to help you with ketosis but only contains 2.3 g of net carbs per cup (6).
• Vegetable broth is another alternative for vegans to dilute miso paste in the soup. One cup of vegetable broth contains 2.1 g of protein, 1.9 g of net carbs, and 0.2 g of fat (5). However, the fat and protein counts are low, so you’ll want to add more ingredients.

The Tasteful Touches of Miso Soup

Miso soup wouldn’t be the same without some key ingredients. Seaweed is an essential ingredient in many traditional-style miso soups. Wakame and arame are two popular choices (14). Wakame seaweed is dark green with a sweet, savory flavorsome blend. 

Meanwhile, arame is a lighter green seaweed with a mild flavor. Don’t mistake these ingredients for kombu, the seaweed used to make dashi broth (23). The floating seaweed is typically arame or wakame. Some recipes use kombu seaweed to make broth from scratch.

Additionally, use other ingredients to add flavor and texture, some including (13, 14):

• Boiled eggs for more protein
• Coconut milk for a thicker, creamier texture
• Garlic and ginger root for a bolder flavor
• Grass-fed butter, olive oil, or MCT oil for added healthy fat
• Sesame oil for an authentic taste with added fat
• Scallions or green onions for crunchy veggies in the soup
• Tamari sauce to replace soy sauce

Miso Soup Ingredient Benefits

Pakistan researchers describe that miso’s fermented qualities may support a healthy gut (21). The koji enzymes used to ferment soybeans promote friendly bacteria in the stomach. The review also confirms how miso may act as an anti-cancer, heart-healthy, and anti-obesity agent.

WebMD states that the key probiotic is called A. Oryzae, which may reduce your risk of inflammatory bowel disease (22). Also, soybean isoflavones may lower the risk of stroke and heart disease while improving arterial function to reduce menopausal symptoms in women. 

Meanwhile, Japanese researchers found that miso’s probiotic qualities improved immune responses in mice (10).

A miso soup keto Reddit recipe reveals how to shake things up further (19). It’s one example of how you can alter your miso soup recipes with other keto-friendly ingredients. However, experiments can be bold on keto. Instead, let’s look at some soups you can eat. 

A simple tomato and basil soup is keto-friendly. A cup of tomato basil soup only contains 8.6 g of net carbs with 3.6 g of protein and 6.3 g of fat (15). The soup has no artificial sweeteners or sugar and provides moderate fat. 

Cabbage soup is an excellent keto-friendly dish you can enjoy as comfort food on cold days. A bowl of cabbage soup contains 8.9 g of net carbs with 3.4 g of protein and 12 g of fat (11). The fat content versus carbs isn’t bad for a hot meal during shivering months.
