I would take issue with the claim made above about “knowing people who only eat 3-4 times a day and do just as well”. Just as well as what? As well as others who eat 6-7 times a day? Doesn’t prove anything, really, since everyone’s individual genetics are different.
My experience has been that I know a LOT of people who went from 3 meals a day to a higher number and made better gains. (In fact, for a lot of them, it’s no exaggeration to say that they started making gains once they did this.) In these cases, there was a definite improvement with more frequent feedings.
I can’t name even one individual (not to say that there aren’t any out there) who has tried 6-7 meals a day and gained less that way. I don’t even know anyone who tried 6-7 and then voluntarily went back to 3 (although I do know people who have been forced into it by work schedules, etc.).
So that (coupled with my own personal experience, of course) is why I think that 6-7 is better. But trying to compare one person who does things one way to another who does them a different way doesn’t demonstrate anything.
