Therefore, the amount of protein in muscle is determined in large part by the balance between a positive nitrogen balance, which promotes protein anabolism (growth or build-up), and a negative nitrogen balance, which promotes catabolism.
In this situation, the body is forced into a negative nitrogen balance, which means a greater amount of protein is lost than what is replaced because of less protein/energy intake.
Negative nitrogen balance means more nitrogen is being excreted than consumed, and thus muscle is breaking down.
