For enthusiasts of seafood and Japanese cuisine, sushi is often a go-to choice. It's not only delicious but also considered a potentially healthy option. However, navigating the world of sushi can be tricky, especially when following a specific diet like the ketogenic diet. This article explores whether sashimi is keto-friendly, providing insights and tips for enjoying Japanese cuisine while staying within your keto guidelines.
Understanding the Keto Diet and Sushi
The ketogenic (keto) diet is characterized by a very low carbohydrate intake (typically less than 50 grams per day), a high fat intake, and a moderate protein intake. This dietary approach forces the body to enter a state of ketosis, where it burns fat for fuel instead of carbohydrates.
Sushi, in its traditional form, presents a challenge for keto dieters due to its primary ingredient: rice. Sushi rice, unlike plain white rice, is seasoned with sugar and rice vinegar, significantly increasing its carbohydrate content. Different types of sushi, such as nigiri, maki, uramaki, and temaki, all contain rice, making them less suitable for a keto diet. For example, a tuna roll with rice and raw tuna contains approximately 4.59 grams of total carbs.
Sashimi: A Keto-Friendly Option
The good news is that you can still enjoy Japanese cuisine while adhering to a keto diet. The key is to choose the right options. Sashimi stands out as a particularly keto-friendly choice. The main difference between sashimi and sushi is that sashimi is served without rice. It consists of thinly sliced, plain raw fish, such as mackerel, tuna, and salmon.
Health Benefits of Sashimi
Sashimi offers several health benefits, especially when made with fish like salmon. Salmon is rich in vitamin B, which can help reduce inflammation and support cardiovascular health.

Navigating Sushi Restaurants on Keto
Dining at a Japanese restaurant while on keto requires careful consideration of the menu. Many Japanese dishes contain ingredients that are not keto-friendly, such as rice, breading, soy, sugar, and starch.
Foods to Avoid:
- Rice: Whether sushi rice, white rice, or brown rice, all types of rice are high in carbohydrates.
- Tempura Breading: Some sushi rolls are coated or fried with tempura breading, which adds extra carbs.
- Excessive Soy Sauce: While soy sauce in moderation may be acceptable, be mindful of the net carb content of certain soy sauces.
- Added Sugar and Starch: These are common in Japanese foods like tamago (egg) and imitation crab meat, as well as side dishes like pickled ginger and wasabi.
- Teriyaki Sauce: This sauce is typically high in sugar and made with ingredients like molasses or rice syrup.
- Imitation Crab Meat: Often found in sushi rolls, imitation crab meat is made from pulverized white fish mixed with fillers, binders, and sugars.
- Seaweed Salad: Despite sounding healthy, seaweed salad is often prepared with a brine that contains a significant amount of sugar.
Keto-Friendly Choices:
- Sashimi: As mentioned earlier, sashimi is an excellent choice because it is simply raw fish without rice.
- Naruto Rolls: These rolls contain no rice, making them a suitable alternative to traditional sushi rolls.
- Rice-Free Sushi Bowls: Also known as poke bowls or chirashi bowls, these are essentially salad versions of sushi rolls without the rice.
- Edamame: Despite being a legume, edamame can be a keto-friendly side dish when consumed in moderation.
- Miso Soup: A staple in Japanese cuisine, miso soup is a clear broth flavored with fermented soybean paste and often contains keto-friendly vegetables like cabbage, mushroom, or onions, as well as tofu.
- Seaweed Salad: Be cautious, as mentioned above, due to the sugar content in the brine.
- Chicken Skewers: Plain chicken skewers (or shrimp, fish, or steak skewers) can provide an additional source of protein.
- Negimaki: Thinly sliced grilled beef.
Tips for Ordering Keto Sushi:
- Skip the Rice: The most important rule is to avoid any dish containing rice.
- Avoid Tempura: Steer clear of anything coated in tempura breading.
- Request Customization: Don't hesitate to ask the chef to customize your meal to fit your keto macros.
- Be Mindful of Sauces: Ask about the ingredients in sauces and avoid those with added sugar or starch.
"Dirty Keto" and Sashimi
Some consider sashimi to be "dirty keto" because, while it is low in carbohydrates, it can sometimes contain unhealthy ingredients like sugar. "Dirty keto" refers to low-carb foods that may not be the most nutritious choices. While consuming these foods may still lead to ketosis and weight loss, it's generally better to opt for nutrient-rich, low-carb options like broccoli, olives, and mackerel.
The Issue with Sugar
Sugar is a high-glycemic sweetener that can raise blood sugar levels and hinder ketosis. When enjoying sashimi, be mindful of any added sugar in sauces or seasonings. Consider using keto-friendly sweeteners like stevia, monk fruit, or erythritol as alternatives.
Ingredient Awareness
Be aware of the ingredients in your sashimi and any accompanying sauces. For example, wasabi may contain sugar, and some soy sauces may have higher carbohydrate content than others.
Example Ingredients Checker:
- Salmon: Atlantic Salmon (Salmo Salar)
- Wasabi: Wasabi, Horseradish, Sugar, Vegetable Fats and Oil, Salt
- Soy Sauce: Water, Soybeans, Salt
Making Keto Sushi at Home
To have more control over the ingredients, consider making keto sushi at home. This allows you to avoid hidden sugars and starches and customize your meal to fit your specific dietary needs.

The Origin of Sushi
It's interesting to note the origin of sushi. It was first created in Southeast Asia and Southern China, with the original form being introduced to Japan in the 8th century. Initially, fish was salted and wrapped in fermented rice as a method of preservation. The fermented rice kept the fish fresh for up to a year. The word "sushi" itself translates to "sour rice." The sushi we know today has evolved over time into a roll shaped with seaweed and cut into bite-sized pieces.
