hmmmmm....
eat protein, lift weights, adjust calories according to goal.
^^ theres your basic set up.
now experiment and find what works best for you. amount of carbs, amount of fat, amount of protein, meal frequency, food choices, total calories, training intensity, training volume, training frequency, rest between sets, rep range, days off, cardio type/intensity/duration/frequency..
same goes for one you step up to the juice level.. experiment with all the different types, start low, work your way up if need be, try combining different types if necessary, etc.
only way to really get the best results is through personal trial and error and consistent effort.
forget all the shit youve read about science, nutrition, physiology, endocrinology, bodybuilders, etc etc..
okay.. im done preaching now
