Imitation crab meat, also known as surimi, is a common ingredient in dishes like sushi, salads, and seafood platters. It’s made to look and taste like real crab but at a lower cost. However, if you’re on a keto diet, you might wonder, is imitation crab meat keto?

The direct answer is no, imitation crab meat is not keto-friendly. It contains added starches and sugars, making it high in carbohydrates. However, there are a lot of great alternatives for this so let’s find out!
What Is Imitation Crab Meat?
Imitation crab meat is not actually crab; it’s a processed product made from white fish, usually, pollock, combined with other ingredients like starches, flavorings, and sugar. The fish is ground into a paste, shaped, and colored to resemble real crab meat.
While it’s a budget-friendly alternative to real crab, the added ingredients are what make it a poor choice for those following a keto diet.
Carb Content in Imitation Crab
One of the biggest issues with imitation crab meat is its carbohydrate content. Unlike real crab, which is naturally low in carbs, imitation crab often contains added fillers like wheat or corn starch and sugars. These ingredients increase the carb content significantly.
Food Item | Serving Size | Carb Content (grams) | Keto-Friendly? |
Imitation Crab Meat | 3 oz (85g) | 12-15g | No |
Real Crab Meat | 3 oz (85g) | 0g | Yes |
Shrimp | 3 oz (85g) | 0g | Yes |
Lobster | 3 oz (85g) | 0g | Yes |
Salmon | 3 oz (85g) | 0g | Yes |
Tuna (Canned in Water) | 3 oz (85g) | 0g | Yes |
Other Ingredients to Watch For
In addition to being high in carbs, imitation crab may contain other non-keto-friendly ingredients:
Added sugars: Some brands include sugar to improve flavor, which contributes to higher carb content.
Preservatives: To extend shelf life, manufacturers may use preservatives that are not ideal for a clean keto diet.
Artificial flavorings and colorings: These additives are often used to mimic the taste and appearance of real crab, but they don’t offer any nutritional value.

Why Real Crab Meat Is a Better Choice
If you’re craving crab, your best option is to choose real crab meat. Real crab is naturally low in carbs and high in protein, making it perfect for keto. For example, a 3-ounce serving of real crab contains 0 grams of carbohydrates and is a rich source of vitamins, minerals, and omega-3 fatty acids.
Real crab also has a cleaner ingredient profile. It’s free from the fillers, sugars, and preservatives found in imitation crab, which means it won’t spike your carbs or interfere with ketosis. Whether fresh or canned, real crab is a far superior choice for anyone following a ketogenic diet.
Low-Carb Seafood Alternatives to Imitation Crab
If real crab is unavailable or you want other seafood options, consider these keto-friendly alternatives:
Shrimp: High in protein and low in carbs, shrimp can be used in many dishes like salads or stir-fries.
Lobster: Rich in flavor and low in carbs, lobster is a luxurious seafood choice that fits well into the keto lifestyle.
Salmon: Full of healthy fats, salmon is perfect for keto meals and can easily replace imitation crab in salads or seafood dishes.

Is Imitation Crab Ever Okay on Keto?
While it’s clear that imitation crab is high in carbs and not the best option for keto, some people may still wonder if it’s ever okay to eat in small amounts. If you’re following a strict keto diet, it’s best to avoid imitation crab entirely due to the added sugars and starches.
However, if you’re on a more flexible low-carb diet and you really want to enjoy a dish with imitation crab, you could work it into your meal plan. Just keep in mind that even a small serving can use up a large portion of your carb limit for the day.
In that case, make sure the rest of your meals are extremely low in carbs to stay within your daily limit.
How to Spot Keto-Friendly Crab Products
When shopping for crab products, always check the labels. Here’s what to look for:
- Carb Content – Real crab meat should have 0 grams of carbs. If you see any carb content, it likely contains added ingredients that aren’t keto-friendly.
- Ingredient List – Look for products without added sugars, starches, or preservatives.
- Wild-Caught – Whenever possible, choose wild-caught crab. It’s generally cleaner and higher in nutrients than farmed seafood.
Conclusion
Imitation crab meat is not keto-friendly due to its high carb content from added starches and sugars. Instead, opt for real crab meat or other low-carb seafood options like shrimp, lobster, or salmon. Real crab is a much better fit for the keto diet, providing healthy fats and protein without the added carbs.
