I used to believe that it was absolutely necessary to eat something post-work out.
It's been two weeks that I began fasting for at least 4 hours (it's because of my schedule) after working out, and I actually don't feel muscle soreness at all! I have even made the weights more intense.
Previously, when eating a can of tuna or a shake(~30 grams of protein both) I would be sore for the next two days.
Why is that? What has my body done? Has it adapted to not getting food after intense training? I don't even think that I am losing muscle.
Btw, I can't find any info on post-workout fasting online...
