Catfish is a popular, affordable freshwater fish enjoyed fried, grilled, or blackened. While it's an excellent source of protein and healthy fats, many people wonder about its carbohydrate content, especially when following low-carb, keto, or diabetic-friendly diets. This calculator helps you determine the exact grams of carbohydrates in your catfish serving based on the amount you plan to eat.
Simply enter the weight of your catfish (in grams or ounces) and select the preparation method — raw, baked, grilled, or fried. The calculator instantly estimates the total carbs, net carbs, and calories, giving you a clear picture of how catfish fits into your daily macronutrient goals. Whether you're tracking macros, managing blood sugar, or just curious about your meal, this tool provides quick, reliable numbers.
Use the quick-fill buttons for common serving sizes, or input your own values for a personalized result. The breakdown shows carbs from the fish itself plus any added from breading or flour, so you can make informed choices about your meal.

How to Use This Tool
Enter the weight of your catfish in grams or ounces, select the preparation method (raw, baked/grilled, or fried), and click Calculate. The tool instantly shows total carbohydrates, net carbs, calories, protein, and fat for your serving. Use the quick-fill buttons for common portions like 100 g or 4 oz, or type in any custom amount.
For the most accurate results, weigh your catfish before cooking if possible. If you're tracking macros, note that the values are estimates based on standard USDA data and can vary slightly depending on the exact cut, cooking method, and any added ingredients.
How It Works
The calculator uses per-100-gram nutritional values for catfish from the USDA FoodData Central database. Raw catfish contains essentially zero carbohydrates, while baked or grilled catfish also has negligible carbs. Fried catfish, however, gains carbohydrates from the breading or flour coating — typically around 8.5 grams per 100 grams of cooked fish.
The formula is simple: total carbs = (carbs per 100g × weight in grams) / 100. Net carbs are calculated as total carbs minus fiber, but since catfish contains no fiber, net carbs equal total carbs. Calories and other macros are computed similarly using standard values for each preparation method.
Worked Examples
Example 1: You eat a 150 g fillet of baked catfish. Total carbs = (0 × 150) / 100 = 0 g. Calories = (162 × 150) / 100 = 243 kcal.
Example 2: You have a 200 g serving of fried catfish. Total carbs = (8.5 × 200) / 100 = 17 g. Net carbs = 17 g. Calories = (229 × 200) / 100 = 458 kcal.
Tips & Best Practices
- For low-carb or keto diets, choose raw, baked, or grilled catfish to keep carbs at zero.
- If you're frying at home, use almond flour or crushed pork rinds instead of wheat flour to reduce carbs significantly.
- Remember that sauces, marinades, and sides (like hush puppies or fries) add extra carbs — account for them separately.
- Weigh your food after cooking for more accurate tracking, as water loss concentrates nutrients.
Factors Affecting Accuracy
Nutritional values can vary based on the catfish species, farming conditions, and cooking method. The USDA data used here represents averages for farm-raised channel catfish, the most common type in the U.S. Wild catfish may have slightly different fat content. Additionally, the amount of breading on fried catfish can vary widely between restaurants and homemade recipes, so the carb estimate for fried catfish is approximate.
Frequently Asked Questions
Is catfish keto-friendly?
Yes, raw or baked catfish contains zero carbs, making it an excellent choice for ketogenic diets. Even fried catfish can fit into a keto diet if you keep the portion moderate and account for the breading carbs.
Does catfish have any carbs?
Plain catfish (raw, baked, or grilled) has no carbohydrates. Only when breaded and fried does it pick up carbs from the coating.
How many carbs are in a typical fried catfish fillet?
A 150 g fried fillet contains roughly 13 grams of carbs, depending on the thickness of the breading.
Can I use this calculator for other fish?
