Of course I love everyone . Jesus commands me to , and I ' ve never interfered in anyone ' s life . That ' s not what Christ teaches . <| sep |> I don ' t think there ' s enough research to say it 100 % doesn ' t matter . I found this post to be an interesting read . You ' ll see that MPS lasts 12 days after a workout , so with that in mind you just need to ingest protein in the next 12 days . However , you also have increased MPB during and after exercise . It ' s not clear how bad this is for gains , but since eating food or just taking protein helps stop MPB , eating post workout definitely has some potential benefit . The authors warn that by not providing the muscle with AAs and insulin , the following will happenacute increases in MPS after exercise in the absence of EAA nutrition provide a more prolonged rise in MPB such that the net effect is negative muscle protein balance Biolo et al . 1995 . If such EAA deficiency persisted throughout training , this would lead to maladaptation you can ' t build or remodel muscle without amino acids ! It follows that increasing dietary EAA availability after exercise enhances both the magnitude and duration of the increase in MPS Pennings et al . 2011 . Therefore , in essence , exercise is able to precondition muscle to delay the muscle full ' setpoint ' Still , it ' s mostly theoretical . Who knows , you might be able to make great progress without any post workout nutrition .
