Is Crawfish Keto? Yes, but Avoid These Ingredients in Your Boil

Keto dieters who are seafood lovers oftentimes wonder “Is crawfish keto, or how many carbs are in crawfish?”⁵

Crawfish, a staple finger food in many parts of the U.S., especially in Louisiana, is among the keto-friendly crustaceans (a type of shellfish) found in freshwaters like lakes, rivers, and streams.¹

These little critters that taste like shrimp but look like small lobsters are usually boiled with several ingredients seen in etouffee or gumbo, and these extra additives are exactly what should be avoided in your next boil since many of them are high in carbs.

The following guide will explain how crawfish is actually keto, which ingredients to look out for at the next crawfish boil, and three keto friendly crawfish boil recipes for those who can’t get enough Cajun food.

Carbs In Crawfish + Does Crawfish Have Carbs?

Crawfish, which are perfect for anyone focused on nutrition, are packed with beneficial micronutrients, and this is why they are a common delicacy.

They are an excellent source of lean protein (25 grams in every 5-ounce serving), fitting into various dietary approaches. Most importantly, crawfish have low-fat content and zero carbohydrates.

These crustaceans are perfect for beginners looking into other weight loss diets, not just the Keto diet. Tracking calories is among the 13 weight loss tips for beginners, and crawfish are low in calories. 

They contain beneficial nutrients such as iron, zinc, calcium, phosphorus, magnesium, and vitamin B.² Crawfish nutritional information per 3 ounces is as follows:

• Protein: 14 grams
• Fiber: None
• Total sugars: None
• Total Carbohydrates: None
• Sodium: 49 mg
• Cholesterol: 97 mg
• Saturated Fat: 0.1 grams
• Total Fat: 0.8 grams
• Calories: 65

Is Crawfish Keto Friendly?

Is crawfish Keto friendly, then? Based on the nutritional profile above, it’s safe to say crawfish alone are Keto friendly but be cautious of the additives that contain carbs.

The lack of carbohydrate content and low fat make them perfect as a stand-alone meal. Most importantly, because they have no carbs, one can have as much as they want and include other items to flavor the dish and meet the 20-40 grams daily carbohydrate intake.

They are great for low-fat vs. low-carb diet plans.

Crawfish are whole foods (exist naturally) and are either wild or farm-raised. Because they are whole food, commercial crawfish are minimally processed.³

Dieticians recommend eating whole foods when on a diet to get nutrients while, at the same time, avoiding processing chemicals. These types of food also decrease the possibility of heart disease, cancer, and type 2 diabetes.

They are also great if you want to monitor how much weight you can lose on the Keto diet. The lack of processing chemicals also means crawfish are free of food additives, highly refined oils, and non-Keto sweeteners.

While a bowl of crawfish is keto friendly or keto safe, the ingredients and additives included in many recipes for preparing the dish may be less Keto friendly. Elements such as rice, potatoes, corn, and other grains often included with this meal are packed with carbs and will ruin your diet.

Advantages and Disadvantages of Eating Crawfish

Looking at the nutritional profile above, several values stand out immediately. Crawfish are a great source of vitamin B12 and protein.

Moreover, they contain high amounts of phosphorus and copper, and these two mineral foods are hard to find in everyday food. What’s more, crawfish provide much-needed minerals such as iron, potassium, and niacin.

Besides having no carbs, these crustaceans also have low calories and are great for people who want to fill their stomachs and still cut down weight. Eating a regular serving of crawfish will provide anyone on a diet with a healthy dose of protein without adding in too many calories.

Even so, it’s not all fun and games when eating crawfish.

First, crawfish can have bacteria that make one sick, causing harmful side effects such as chest pain, weight loss, cough, fever, night sweats, and dyspnea.⁴ Second, eating crawfish can lead to paragonimiasis, an infection affecting organs like the lungs, the skin, and the brain.

Finally, the benefits of eating crawfish depend on how it’s cooked and what accompanies the delicacy. For example, a Cajun crawfish boil contains a lot of sodium which may not be very healthy.

Anyone who decides to fry them will increase the amount of saturated fat and cholesterol, which are enemies of weight loss.

Non-Keto Ingredients & Additives to Avoid In a Cajun Louisiana Crawfish Boil

In such a meal, is crawfish Keto? This meal often contains a variety of ingredients that should not be included in a plate of anyone who is included in a Keto diet.

These ingredients include:

Potatoes: The most common potatoes used with this dish are red potatoes, and they are packed with carbs. Their carbohydrate content is 23g per 5 ounces, (high glycemic index) so they should be avoided altogether.

Corn: This is a starchy grain not recommended in a Keto diet and sometimes comes as “baby corn”. It has a carb content of 27g per 5 ounces (high glycemic index).

Smoked sausage: While smoked sausage is Keto friendly, it contains a low amount of carbs; as such, anyone on a Keto diet should be wary about including it on their plate when they have a Cajun Louisiana crawfish boil.

Is Crawfish Bisque Keto Approved?

A Crawfish Bisque has the following nutritional profile per serving:

• Carbohydrates: 25-37g
• Fat: 0g
• Fiber: 1g
• Protein: 2g
• Sodium: 25mg

Based on the profile above, one serving of crawfish Bisque is within the Keto limits. Moreover, the carbs can be reduced to 8 grams per serving by removing the corn and replacing it with mushrooms.

One serving is enough if a person’s dietary carb requirement is under 25g.

Before eating this meal, a person on the Keto diet should consider whether they will eat more food later as they can’t have more carbs for that day. This meal’s daily value percentage for sodium is tiny.

According to the FDA’s guidelines for sodium intake, this meal should be supplemented with another sodium-rich meal before the end of the day.
