Its something I've read in other peoples journals, and generally at the level that most people train at, 3 quality meals that cover your diet requirements for the day is better than 6-7 'small' meals that may not match the same nutritional value. I used to try and eat the 6-7 meals per day, but have moved away from it as I felt I gained nothing, and it was a little inconvenient. I probably came across a little heavy in saying its a myth, but it is a common thing to hear people say that eating less more often is the key to losing weight. Think about it like this. If you eat/drink badly for a week, and then have one day where you eat well, is that going to improve your ability to workout? I would think not, and it works the other way around, if you eat well for a week and have one bad day it feels the same. I'm only going on my personal experience and the experience of others that are exceptional bodybuilders, but if someone has some science to back up the claim I'd be glad to hear it.
