Imitation Crab Calories, Every Way You Measure
About 17 per stick, 81 per 3-ounce serving — and the interesting math is in what the crab is dressed in.
Imitation crab is a genuinely low-calorie food: about 81 calories per 3 oz serving, which works out to roughly 17 calories per standard leg-style stick. A whole cup of flaked surimi — more than most recipes use per person — lands around 130 calories. The catch, as with most light ingredients, is that almost nobody eats it plain: mayo, cream cheese, batter, and rice do the heavy caloric lifting in surimi dishes, and the table below shows exactly where the numbers move.
The base numbers
| Amount | Calories | Protein | Carbs |
|---|---|---|---|
| 1 leg-style stick (~2/3 oz) | ~17 | ~1.5 g | ~3 g |
| 3 oz serving (standard) | ~81 | ~6.5 g | ~13 g |
| 1 cup, flaked (~4.75 oz) | ~130 | ~10 g | ~20 g |
| 8 oz package | ~215 | ~17 g | ~34 g |
Calculated from USDA FoodData Central (imitation crab, FDC 174203: 95 kcal, 7.6 g protein, 15 g carbs per 100 g). Stick weights vary by brand.
Brands vary a little with their starch and sugar levels — labels we checked run from about 75 to 120 calories per 3 oz. The carbs deserve their own note: 13 g per serving is a lot for a "seafood," which is why surimi and keto don't get along. The full macro picture, sodium included (about 450 mg per serving in USDA data, up to ~700 mg on some labels — the real nutritional watch-item; see imitation crab sodium), is in the nutrition guide.
What dishes actually cost
| Dish | Typical serving | Calories | Where they come from |
|---|---|---|---|
| Kani salad | 1 serving | ~210 | Kewpie mayo is well over half the total |
| Kani cucumber salad | 1 serving | ~115 | The light-dressing alternative (without mayo) |
| California roll | 1 half-sheet roll (8 pcs) | ~255 | Mostly rice and avocado; the crab is ~27 |
| Crab rangoon | 4 pieces | ~260–330 | Cream cheese + wrapper; deep-frying adds the most |
| Crab mac & cheese | 1 serving | ~780 | Pasta and cheese sauce; the crab is ~55 |

The pattern is consistent: in the rich dishes, the crab is a small share of the calories (only light dishes like the cucumber salad are crab-led). Choose dishes by their dressing and carbohydrate base, not their crab content, and the totals follow.
Comparisons worth knowing
Ounce for ounce, imitation crab is about as light as real king crab (~82 calories per 3 oz) — but real crab more than doubles the protein at the same calories, which is the better deal if the budget allows (the full comparison). Against deli meats, surimi wins comfortably on calories if not sodium. If you're tracking seriously, a kitchen scale beats stick-counting — stick sizes vary between brands.
Is it a good weight-loss food?
Mixed. In its favor: the calorie density is genuinely low, and shredded surimi bulks up salads and rice bowls cheaply. Against it: at about 6–7 g of protein per serving it's a mediocre protein source, and protein is what drives satiety per calorie — 81 calories of imitation crab keeps you full for less time than 84 calories of cooked shrimp with about three times the protein (~20 g). A sensible pattern: use surimi for flavor and volume, but anchor the meal's protein elsewhere. The kani cucumber salad is the template — big volume, bright flavor, modest calories — and it's easy to add a boiled egg or edamame alongside.
The bottom line
Count on ~17 per stick, ~81 per serving, ~130 per cup — and put your attention on the mayo, cheese, batter, and rice around it. Surimi itself is one of the cheapest caloric seats at the seafood table.
