IF style eating and protein response from low glycogen levles

    For those that are interested in IF and its partitioning affects i have a question...

    The 8 hour feast is designed to build muscle and minimize fat gain,however, after the fast when you come to workout your glycogen levels will be low..

    Will low glycogen levels affect the magnitude of increase in protein synthesis following your workout?? or affect muscle growth in the next 24 hours??

    Most likely what will happen is that a lot of the carbs you take in post-workout will go to refilling glycogen... which is fine. Personally, I just hope to build enough protein in that period to make up for whatever protein I lost during the fast.

    Doesn't look like it from what I can garner from the LeanGains site and Lyle's site. As I understand it too, working out in a 'fasted' state is a bit of a misnomer because I've routinely seen recommendations to down some BCAAs or whey right before you start working out. Like T says, you'll see glycogen repletion but I don't think there will be any effect on protein synthesis.

    I really don't think you will be all that glycogen depleted prior to the workout anyway unless you are really cutting the calories hard during the 8 hour window that you are eating. 16 hours of fasting with just normal day to day activity isn't going to deplete you. If you've ever done depletions on UD2.0 then you'd know the difference between working out on an empty stomach and working out when glycogen depleted... often during fasted workouts, I felt fine. But if it is a concern then just do as CDB pointed out has been recommended elsewhere - break the fast with some protein, bcaas or whatever prior to the workout.
