just my .02. as important as quantity and quality of food is, it is equally important to eat at regular intervals, especially if you sleep for seven or eight hours per night (which i dont). when i have a solid breakfast and eat every three hours or so, training imporves, no mood swings (probably related to stable blood sugar?) and have more energy and mental acuity. if you rise in the morning and have a sammy davis breakfast, i.e. two black coffees, a danish and a few marlboros, forget about making any gains. proper nutrition and feeding frequency requires as much discipline as whatever traing methodology you are following.
