How Many Calories Are in Miso Soup?
Miso soup is generally considered a low-calorie soup, but its calorie content varies depending on portion size, miso paste amount, and added ingredients such as tofu or vegetables.

Miso soup calories per serving
A standard serving of miso soup contains approximately 35–70 calories. This range reflects differences between homemade, restaurant, and instant miso soup, as well as the type of miso used.
Miso soup calories per cup
One cup of miso soup (about 240 ml) typically contains 40–60 calories. Most calories come from miso paste rather than the broth itself.
Miso soup calories per bowl
A restaurant bowl of miso soup usually contains 50–90 calories, depending on bowl size and whether tofu, seaweed, or vegetables are included.
Miso soup calories per 100g
Miso soup contains approximately 15–25 calories per 100 g, making it one of the lowest-calorie soup options.
Miso Soup Nutrition Facts
Miso soup is low in calories but provides small amounts of protein and carbohydrates, along with notable sodium content.
Miso soup calories, carbs, protein, and fat
A typical cup of miso soup provides:
-
Calories: 40–60 kcal
-
Carbohydrates: 4–7 g
-
Protein: 2–4 g
-
Fat: 1–3 g
The exact balance depends on the miso type and added ingredients.
Carbohydrates in miso soup
Carbohydrates mainly come from fermented soybeans in miso paste. Miso soup is relatively low in carbs compared to noodle-based soups.
Protein in miso soup
Protein comes primarily from soybeans and tofu. While miso soup is not a high-protein food, it contributes modest plant-based protein.
Fat content in miso soup
Miso soup is generally low in fat. Any fat present comes from soybeans or tofu rather than added oils.
Fiber in miso soup
Miso soup contains small amounts of fiber, usually less than 1 g per serving. Fiber increases slightly when vegetables or seaweed are added.
Sugar content in miso soup
Miso soup contains very little sugar, typically under 1 g per serving. Some miso pastes naturally contain trace sugars from fermentation.
Sodium in miso soup
Miso soup is high in sodium, often providing 600–900 mg per cup. This comes primarily from miso paste and dashi broth. Sodium content is the main nutritional concern with frequent consumption.
Calories in Different Types of Miso Soup
Different miso varieties affect both calorie content and flavor intensity.

White miso soup calories (shiro miso)
White miso soup typically contains 45–70 calories per cup. White miso is slightly sweeter and often used in lighter soups.
Yellow miso soup calories
Yellow miso soup usually contains 40–65 calories per cup. It has a balanced flavor and moderate sodium level.
Red miso soup calories (aka miso)
Red miso soup tends to be 40–60 calories per cup. It has a stronger flavor, so less paste may be used, keeping calories similar.
Mixed miso soup calories
Mixed miso soup (a blend of white and red miso) generally contains 45–70 calories per cup, depending on the ratio used.
Vegan miso soup calories
Vegan miso soup usually contains 35–60 calories per cup, especially when made with vegetables instead of tofu or fish-based dashi.
Traditional Japanese miso soup calories
Traditional Japanese miso soup, made with dashi, miso paste, tofu, and wakame, typically contains 40–70 calories per serving.
Is Miso Soup Healthy or Fattening?
Miso soup is generally considered a healthy, low-calorie food, but its overall impact depends on portion size, sodium intake, and frequency of consumption.
Is miso soup low calorie?
Yes. Miso soup is low in calories, typically providing 35–70 calories per serving. Most of the soup is broth, with calories coming mainly from miso paste and small additions like tofu or seaweed.
Is miso soup good for weight loss?
Miso soup can support weight loss when consumed in moderation. Its low calorie density and warm, savory flavor may help increase satiety, making it useful as a meal starter or light side dish.
Is miso soup fattening?
No. Miso soup is not fattening on its own. Weight gain would only occur if total daily calorie intake consistently exceeds needs. Miso soup is low in fat and calories compared to most soups.
How miso soup fits into a calorie-controlled diet
Miso soup fits well into a calorie-controlled diet as:
-
A low-calorie appetizer
-
A replacement for higher-calorie soups
-
A light snack between meals
The main consideration is sodium intake, especially if consumed frequently.
Best time to eat miso soup for weight management
Miso soup is often most effective when eaten:
-
Before meals, to promote fullness
-
With meals, as a low-calorie side
-
In the evening, as a light, warm option instead of heavier foods
Timing matters less than overall portion control and diet balance.

How to Reduce Calories in Miso Soup
Although miso soup is already low in calories, small adjustments can reduce calorie and sodium intake further.
Use less miso paste
Reducing the amount of miso paste lowers both calories and sodium. Using slightly less paste still preserves flavor when combined with vegetables or seaweed.
Add more vegetables instead of tofu
Vegetables such as mushrooms, spinach, or green onions add volume and nutrients with very few calories, compared to tofu, which is more calorie-dense.
Choose low-sodium miso
Low-sodium miso paste helps reduce salt intake without significantly affecting calorie content, making it better for frequent consumption.
Control portion size
Stick to one cup or one small bowl per serving. Larger bowls increase sodium intake more than calories but can still affect overall dietary balance.
Make miso soup at home for calorie control
Homemade miso soup allows you to:
-
Control miso paste quantity
-
Choose ingredients carefully
-
Avoid excess sodium
This is the most effective way to manage both calories and nutrition.
