Calories by Type

Queen crab tends to be higher in calories than any other type of crab meat. You'll get nearly 100 calories from 3 ounces of steamed queen crab. If you prefer the decadent flavor of Alaska king crab, you'll save a few calories. A 3-ounce of cooked Alaska king crab yields closer to 80 calories. Steamed Dungeness crab is on the higher end, offering almost 95 calories from 3 ounces. If you're really counting calories and trying to limit your intake, opt for blue crab. A 3-ounce serving of either steamed or canned blue crab gives you around 70 calories, 30 percent less than the same amount of queen crab.
