Good to Know
A 3 oz portion gives you 16.5 g of protein for just 82 calories, which makes king crab one of the leanest proteins on the menu. Watch for imitation crab (often labeled surimi or krab), since brands like Louis Kemp and Trans-Ocean bind it with starch and sugar and can run 12 to 14 g of carbs per serving. Buy legs sold as plain frozen or steamed, and skip the breaded crab cakes and the sweet cocktail sauce, which both sneak carbs onto an otherwise zero-carb plate.
