How come you don’t gain muscle even when working out if you have a calorie or protein deficit. Maybe my understanding is an oversimplication but I thought muscle growth was from repairing tiny tears you get from working out. If these tears still occur why does growth not occur? Does it occur? Does it just happen but less efficiently?

muscles are made of protein. How do you expect to get larger protein tubes on your arm if you have no protein to put in them?
