About 74% of the calories in spiny lobster come from protein, which makes it extremely protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Weight for weight, spiny lobster has 13.6 g of protein for each gram of fat (26.4 g against 1.94 g per 100 g).
Set against chum salmon, another seafood entry in the database, a serving carries about 0.5 g more protein (chum salmon has 21.9 g per 3 oz cooked).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 85 g, and it covers about 45% of the 50 g FDA Daily Value for protein.
