If there is a need to synthesize new muscle tissue from trauma from weightraining, I dont udnersatnd how at the end of the day total caloric intake is going to determine whether you grow. If a 250lb male competitive bber eats 400 grams of protein per day and only eats 2000 cals cant they still grow as fast as someone eating 4000 cals as long as glycogen levels are not at zero?
