nutrition is the chief factor controlling muscle loss/gain. Overtraining really is secondary. In fact, if you were to find a program and deliberately overtrain while juicing and eating a lot -- you'd make great gains. Especially because you'd have to train with more volume or frequency to overtrain, and both of those build muscle faster.
Of course if you want to gain more it's easier just to up the dose than try and manipulate training variables
