Scallops are a lean, high-protein seafood favorite, but their carbohydrate count depends heavily on how they are prepared. A 100 g portion of raw scallops contains about 3.2 g of carbs, while the same weight of steamed or pan-seared scallops contains about 6.3 g because cooking removes water and concentrates nutrients. Breaded and fried scallops are higher still, with roughly 16 g of carbs per 100 g due to the flour coating and oil. This makes scallop portion tracking a genuinely useful step for low-carb and keto meal plans.
This calculator takes the guesswork out of logging scallops. Enter the amount you plan to eat, pick a unit (grams, ounces, pounds, or whole scallops), choose the preparation most similar to your meal, and the tool estimates total carbs, net carbs, protein, fat, and calories using USDA-based reference values.
Whether you are counting macronutrients, managing blood sugar, or simply curious about the nutrition in your seafood dinner, this scallop carb calculator gives you a quick, practical answer in seconds.
🦪 Scallop Carbs Calculator
Estimate the carbohydrate and macro content of fresh, cooked, or breaded scallops.
Quick Start
Enter the amount of scallops you plan to eat in the first field. Choose the unit that matches how you measured it: grams, ounces, pounds, large scallops (about 20 g each), or small scallops (about 10 g each). Next, choose the preparation style that most closely matches your meal: raw, steamed or pan-seared without coating, or breaded and fried. The calculator converts everything to grams, then applies the appropriate 100 g reference value. Press Calculate carbs to see estimated total carbohydrates, net carbohydrates, protein, fat, and calories. The Reset button clears the form so you can start a new entry. The quick-pick buttons are handy starting points: tap “85 g raw,” “4 oz steamed,” or “6 oz breaded,” then adjust the numbers as needed.
This tool is especially useful for keto and low-carb meal planning, diabetic meal prep, or simply logging a seafood dinner accurately. You can quickly compare plain versus breaded scallops before you order or cook.
How the Calculation Works
These estimates are based on the USDA FoodData Central reference values for scallops (mixed species). For each nutrient, the formula is: nutrient per 100 g × (weight in grams ÷ 100). For carbohydrates specifically: (carbs per 100 g) × weight grams / 100. For example, if a food contains 6.26 g carbs per 100 g and you eat 113.4 g, the math is 6.26 × 1.134 = 7.1 g.
Scallops contain negligible dietary fiber, so net carbs are effectively the same as total carbs. The tool also calculates protein, fat, and calories using the same proportion. That gives you a complete macro snapshot without switching tools. Values from the USDA are averages across mixed species; individual scallops can vary by season, harvest location, and cooking time, but the estimate is close enough for daily tracking.
Reference Nutrition Values
The table below lists the reference values used by this calculator, per 100 g of edible portion.
| Preparation | Carbs (g) | Protein (g) | Fat (g) | Calories |
|---|---|---|---|---|
| Raw scallops | 3.18 | 16.78 | 0.76 | 88 |
| Steamed / pan-seared (no coating) | 6.26 | 24.14 | 1.19 | 137 |
| Breaded and fried | 16.35 | 17.70 | 11.00 | 212 |
Raw and cooked values differ mainly because cooking removes water and concentrates the nutrients. Breaded and fried scallops contain wheat flour breading and frying oil, which raises both carbohydrates and fat. Choose the row that matches your meal as closely as possible.
Worked Examples
The following examples show how to use the same math in real portions:
Common Mistakes to Avoid
- Choosing the wrong preparation. Using raw values for a breaded serving will undercount carbs by roughly 13 g per 100 g. Always select the closest cooked method.
- Mixing raw and cooked weights. If you weighed raw scallops, choose raw; if you weighed after cooking, choose cooked. Cooking removes water, so the same cooked weight represents more original scallop meat.
- Ignoring added sauces. Garlic butter, cream sauce, and citrus glazes add carbs and calories. The estimates cover the scallops alone.
- Treating scallops as a zero-carb food. They are low in carbs, but not carb-free. A large restaurant portion of cooked scallops can easily supply 10–15 g of carbs before any sides.
- Forgetting that scallop sizes vary. The “large” and “small” options are approximations. If you have a food scale, weighing in grams is the most reliable method.
Frequently Asked Questions
Are scallops keto-friendly?
Plain scallops can be keto-friendly in moderate servings. An 85 g raw portion provides roughly 2.7 g of carbs, and a 100 g cooked portion provides about 6.3 g. Breaded and fried scallops are harder to fit into a strict keto plan because the coating adds roughly 10 g extra carbs per 100 g.
Do scallops contain sugar?
Scallops contain only negligible amounts of naturally occurring sugar and no added sugar. The carbohydrate in scallops is mostly glycogen, an animal storage carbohydrate, which is digested and tracked like other carbs.
Why do cooked scallops show more carbs per 100 g than raw?
Because cooking removes water and concentrates the remaining nutrients. The same number of scallops weighs less after cooking, so 100 g of cooked scallops contains more actual scallop meat than 100 g of raw scallops.
How accurate is this calculator?
The values are averages from the USDA FoodData Central and are suitable for meal planning, but individual scallops will vary by species, season, and cooking method. For closer tracking, weigh the scallops exactly and choose the preparation carefully.
