I am against waking up to feed one self. Mainly for the fact that it takes 45Mins to 2hours depending on the person to enter REM sleep. This is the type of sleep that is healing and rebuilding the majority of Muscle building happens in REM sleep. So say you go to fall asleep at 12am you might not enter REM sleep till 1 am now you wake up at 6 AM to eat then you to back to sleep by 6:30 and enter REM by 7:30 Now you have to wake up and go to school/work by 8:00.
Thats two hours of time that could have been devoted to REM, rebuilding / healing sleep. Not to even mention that the body's digestion of food can interferer with REM sleep. When we do not get the quality sleep we need, REM, we can not hope for Hypertrophy of any large measure.
Of course on the other side of the spectrum you have those who say we might not have enough Building nutrients to successfully heal and rebuild throughout sleep. So Some believe we need to "re-Fuel" around half way through sleep.
