To determine if he ingested his recommended allowance of protein, we need to first calculate his recommended daily amount of protein. According to the National Academy of Medicine, the recommended daily allowance (RDA) of protein for a sedentary male weighing 154 pounds is 56 grams.

Since this man only consumed 45 grams of protein a day, he did not reach the RDA. However, as two-thirds of his protein intake comes from animal sources, we can estimate that he consumed roughly 30 grams of animal-based protein. This means he consumed 15 grams of plant-based protein.

To meet his recommended daily allowance of protein of 56 grams, he needs an additional 56 - 45 = 11 grams of protein. Therefore, the correct answer is C: he needs 11 grams more protein to meet the recommended allowance.
